Dry Ice And Baking Soda? The 127 Latest Answer

In the winter, keeping your driveways and cars ice-free is a difficult task. But you needn’t worry as HomeQuicks presents easy homemade ice melting solutions for your snowy driveway and car problems.

Quick tip

Spread sand, bird seed, or kitty litter on the driveway. The ice will melt, but the sand and seeds will not. They help you get a grip on the slippery and icy ground.

There are hundreds of commercial ice melting products and services on the market today. They can work wonders to clear ice from roads, but they can leave residue, chemically attack concrete, and damage vegetation.

Aside from using professional ice melters, many people believe in removing ice from the driveway the traditional way. Snow accumulations can be scraped off with a snow shovel to clear the path. Like the simple shovel, snow throwers and other machines help to remove the ice. However, such paths require more physical energy, and therefore one cannot repeat the process over and over again.

Now there’s a simple solution to this problem – making homemade snow melt using simple ingredients that are easy to find around your home. They’re light in your pocket and safe around pets.

Homemade solid ice melt

► salt

Salt is the most basic ice melt you can find in your home. Sprinkle the simple salt over the snowy area. Salt spreads through the layer of ice. Ice melts because salt lowers the freezing point of water. It’s a perfect ice melter for your driveway at no extra cost.

► Fertilizer

Like salt, you can also use fertilizer as ice melt. You don’t have to mix it with anything else. Spread the fertilizer on the snow-covered area. Ammonium sulfate, a common ingredient in fertilizers, speeds up the melting process. Using fertilizers while the ice is melting will prove beneficial to your garden areas. However, they may not be a good idea for your driveways as once mixed with melting ice they can flow into the sewers.

► Baking powder

All you have to do is sprinkle baking soda liberally on the snowy path and wait for the ice to start melting. It contains sodium, which lowers the freezing temperature of ice cream. However, you must be careful not to use the soda-sprinkled trail immediately.

Melting liquid ice homemade

► Rock salt + water

You can use rock salt to melt the ice. Pour warm water into a bucket. Add rock salt crystals. Stir occasionally until the salt crystals have completely dissolved. Pour the rock salt and water solution into a sprayer. Spray the solution over the unwanted snow on the driveway. The saturation power of the sprayer penetrates through all layers of snow and melts it.

To prevent ice formation, add calcium chloride to the solution in a 1:3 ratio to the water used in the solution. Mix well until calcium chloride dissolves. Pour the mixture into the sprayer and spray it over the driveway before the next expected snowfall. It prevents any ice formation in the sprayed area.

► White vinegar + water

Add 1 part white vinegar and mix with 1 part water. Stir the solution well and pour into a sprayer. Spray the solution on snow to melt it. However, you can add more vinegar to the solution if the snow is thick or takes a long time to melt. If you don’t want to use the sprayer, you can pour the solution directly onto the snow-covered area. You can also use this ice melter for windshields.

► Wood ash + white vinegar + water

With these ingredients you can create an ice melt that is also good for your plants. Collect 2 cups of wood ash from your fireplace. Pour it into a gallon of water and let it sit overnight. Remove all floating bits and pieces. Pour the mixture into another bucket; However, do not pour the sediment remaining at the bottom of the bucket. Add 2 cups of white vinegar to the mixture and stir well. Pour the mixture into a sprayer and spray onto the snow you want to melt. It will help you de-ice your sidewalks and sidewalks. In addition, it does not allow for new accumulation of snow.

► Rubbing alcohol + water

This one ingredient is found in commercial ice melts and also in our homes. Rubbing alcohol has a lower freezing point than water. You can just pour it on the ice. It will help you dissolve it. However, you can mix it with water and spray it over the ice covered area. The mix is ​​durable, which comes in handy in the event of an ice melting emergency. Spray all over your frosted windshield and car to melt away the ice.

► Rubbing alcohol + liquid dishwashing detergent + water

Here’s a pet-friendly homemade ice cream melter. Take a quart of warm water and add 2-3 drops of dish soap and 1 ounce of rubbing alcohol. Mix the ingredients well and pour the mixture into a sprayer. Spray it on the icy surface and watch the ice melt.

► Isopropyl alcohol + liquid dish detergent

Here is a miraculous windshield ice melter. Get a bottle of isopropyl alcohol that is 70% pure or higher. Add 2-3 drops of liquid dish soap. Spray the mixture on icy windshields to clean them.

What is dry ice?

A copy of the What is Dry Ice? brochure is available in Adobe Portable Document Format (PDF, 145 KB, 2 pages).

Dry ice is solidified carbon dioxide. When dry ice melts, it turns into carbon dioxide gas. Carbon dioxide gas is always present in the environment, but in low concentrations. It is colorless and odorless.

Use Dry Ice Safely Carbon dioxide gas is heavier than air, so it can collect in basements or other low-ceilinged areas. When transporting dry ice, always keep vehicle windows open to let in fresh air. The amount of dry ice used in a regular freezer or refrigerator is unlikely to produce carbon dioxide gas in sufficient quantities to cause a health problem. Dry ice can easily be used to keep food cool in such containers.

Do I need to take any special precautions when using dry ice?

When handling dry ice, there are a few important precautions to take:

Dry ice is much colder than regular ice and can burn skin in a manner similar to frostbite. When handling, you should wear insulated gloves. Wear safety goggles and a face shield if you cut or chip it.

Keep dry ice out of the reach of children.

Never eat or swallow dry ice.

Avoid breathing carbon dioxide gas.

Can I actually choke on dry ice?

Dry ice can be a very serious hazard in a small space that is not well ventilated. When dry ice melts, it turns into carbon dioxide gas. This gas can accumulate in a small space. If enough carbon dioxide gas is present, a person can become unconscious and in some cases die.

Can I use dry ice in a walk-in fridge or freezer?

It is very dangerous to use dry ice in a walk-in freezer, cooler, enclosed truck bed, or other small space with poor ventilation. A large amount of dry ice in a walk-in refrigerator or freezer can generate a large amount of carbon dioxide, potentially fatal to anyone entering that space.

What are signs that you are being exposed to too much carbon dioxide?

Symptoms of overexposure to carbon dioxide include headaches and difficulty breathing, and with greater exposure, nausea and vomiting.

What are some tips for using dry ice to keep food cool?

Order dry ice in the shape and size you want it to be used in. Cutting can be difficult and dangerous.

Store dry ice in a container that can leak. If not vented, carbon dioxide gas can build up pressure in a jar or container as dry ice melts.

How much dry ice do I need?

The amount of dry ice you need to maintain the temperature in a freezer or refrigerator varies. Some basic tips for using dry ice to chill food are:

In a refrigerator: A home refrigerator can use about 10 pounds of dry ice per day. Dry ice can freeze items, so place food that could be damaged by freezing as far away from dry ice as possible. Put ice on the bottom of a household appliance. Place newspaper or other materials on glass shelves as insulation to prevent the shelves from breaking. Keep liquids tightly covered so they don’t become aerated as the fridge fills up with carbon dioxide.

In a Freezer: A chest freezer can use 40 to 50 pounds per day of dry ice placed on the food.

In a household style fridge freezer: A bottom freezer unit can use 15 to 25 pounds a day when placed on top of groceries. A unit with the freezer on top can use 20 to 30 pounds a day when placed on and around the groceries. A unit with a side-by-side freezer can use 30 to 40 pounds a day when placed on and around food.

How do I dispose of dry ice?

Crystals form when a substance has atoms or molecules that form in a highly organized, repeating 3D pattern. When we think of crystals, we usually think of well-known gemstones like diamonds or rubies, but there are some very common crystals as well. Sugar, ice, snowflakes, salt… these are all crystals. You can grow your own crystals.

Try it at home! You will need:

2 glasses or glasses

1 plate

1 spoon

2 paperclips

Hot tap water

Piece of yarn or cotton cord, about 6 inches long

baking soda

Fill each glass with water. Add 2 tablespoons of baking soda to each glass. Stir the mixture. When all of the baking soda has dissolved, add a little more baking soda and stir. Add baking soda until the water can no longer dissolve it, the mixture is saturated. This means that the water contains as much baking soda as possible. You can add a few drops of food coloring to each jar to make the crystals colorful. Tie a paper clip to each end of the twine or string. Drop a paperclip into each glass and, without touching the plate, dangle the string between the glasses in the shape of a smile. Watch the string over the next few days to see the crystals forming along the string.

The picture on the right shows you what the soda crystals will look like after a few days. As the days go by and the water in the baking soda solution evaporates, the water level will drop. Make sure the end of the string with the paperclip stays submerged in the baking soda water in the jar.

Science experiment idea

Grow more than one type of Crystal. Use salt, sugar and baking soda. Keep a chart as you watch the crystals grow over the next few weeks. Which one do you think will grow the biggest? Which forms the fastest?

Dry ice is a magical addition to any party. Without them, junior high school proms wouldn’t have been the same, Halloween parties wouldn’t be as spooky, and 1980s music videos wouldn’t have left the indelible mark they did.

How to make dry ice like a pro.

What exactly is dry ice?

Dry ice is often confused with its cold cousin, liquid nitrogen. Actually, dry ice is just cooled and condensed carbon dioxide. It skips the melting process and directly sublimes into carbon dioxide gas when it reaches room temperature and pressure. Dry ice is extremely cold, hovering around -109.3 degrees Fahrenheit.

When not being used for rock concert fogging, it is often used to keep perishables cool during shipping. (Thomas Slate was the first to sell it to railcars in 1924.) It also has a number of other intriguing uses. For example, it is used to rid the New York City subway system of rats. Try attaching it to the underside of a RC car for some really radical Fast and Furious effects.

Naturally occurring dry ice is found in abundance on a number of celestial bodies in our solar system, including Mars and several moons of Uranus and Neptune. Seven years ago, NASA’s Mars Obiter Express detected a dry ice avalanche plummeting down the slopes of Mars.

Store-bought dry ice can be expensive and hard to find. Plus, it’s a lot more fun to make something from scratch (at your own risk, of course). Luckily, Popular Mechanics has a super easy recipe for you to create the spooky vapor yourself.

How do you make dry ice?

Gordon Chen / Eyeem Getty Images

It’s actually pretty easy, and you can make it with things you probably already have at home.

Ingredients:

Sturdy gloves

Carbon dioxide fire extinguisher (must be marked C02)

garment bag

⚠️ Because dry ice is so cold, you can actually get frostbite. Make sure these durable gloves can take on the snuff.

Instructions:

Place the nozzle of your Co2 fire extinguisher in the cloth bag and seal tightly. fire away! (Or, depending on the type of extinguisher, open the valve.) Close the extinguisher nozzle or valve. Shake this bag like it’s a polaroid picture. Remove newly formed dry ice from the bag and enjoy.

If you want to keep it cooler for longer, place it in a styrofoam cooler and make sure the lid stays slightly open.

But… Isn’t dry ice dangerous?

Peepo Getty Images

It may be! Remember, this stuff is really, really cold. Prolonged exposure to dry ice can actually freeze your skin cells, leaving you with an injury similar to a burn. If you put it in a fancy drink, be careful not to swallow it. And make sure you dispose of it properly, so don’t drop it in the sink or throw it in the trash. To speed up the sublimation, you can pour hot water into the container you are storing it in.

Also, make sure to use it in a ventilated room. Breathing in too much carbon dioxide can be fatal – especially for children, Fido and Fluffy. Finally, storing dry ice in a sealed container (including your freezer) builds up pressure and can cause the container to explode. Please do not accidentally make a dry ice bomb.

That being said, playing with dry ice can be a lot of fun and can add value to any party. Enjoy.

Sodium acetate trihydrate, commonly referred to as “hot ice,” may seem like a dangerous chemical, but in reality it can be made in your kitchen using vinegar and sodium bicarbonate (baking soda) and poses no danger to you. Not to be confused with “dry ice.” ‘ or ‘Cardice’, which will undoubtedly cause severe burns if exposed to skin. Hot ice is derived from sodium acetate, a key ingredient used in heating pads and hand warmers with water.

A video uploaded by NurdRage shows what exactly would happen if you put your hand in a glass of hot ice. In this video, after coating his hand with sodium acetate, the man puts his hand in “a nice tall jar of liquid sodium acetate dehydrate.” In a matter of seconds, the man’s hand is surrounded by crystallized sodium acetate. Although it looks like the hand is frozen in a glass of ice, the man explains that it actually feels warm to the touch and has the consistency of ice cream.

Sodium acetate trihydrate is a solid at room temperature with a melting point of 136 degrees and a boiling point of 252 degrees Fahrenheit. In addition to heating pads and hand warmers, sodium acetate trihydrate is also used in the food industry for pickling, tanning, and as a buffer in laboratory settings.

What is dry ice?

Dry ice is made by liquefying carbon dioxide and injecting it into a storage tank where it is frozen at a temperature of -109°F and pressed into solid ice. Depending on whether it is made in a pelletizer or block press, dry ice can then be processed into pellets or large blocks.

Unlike regular ice, dry ice does not melt into a liquid when heated. Instead, it converts directly back to its gaseous form in a process known as sublimation. At -109°F, dry ice is also significantly colder than the 32°F surface temperature of regular ice.

History of Dry Ice

Dry ice was discovered in the early 1900s and first entered commercial production in the 1920s. The name “dry ice” has been in use since 1925, when a manufacturer first trademarked it. Commonly used in commercial settings, the connection is versatile and provides benefits across a wide range of industries.

For example, the food and agriculture sectors use dry ice to prevent food from spoiling in transit. Due to its low temperature, dry ice inhibits bacterial growth and slows down decomposition, making food crunchier, fresher and tastier for as long as possible.

There are a variety of other uses in commercial settings. For example, the entertainment industry uses dry ice to create a smoky effect without an open flame.

Pest control technicians use it to force gophers out of their holes, allowing the technician to close the burrows without harming wildlife. Dry ice can also lure mosquitoes away from people and clean sensitive electronics without harsh chemical solvents.

dry ice security

Anyone can reap the many benefits of dry ice, but there are some safety techniques to keep in mind:

Wear thick gloves before handling dry ice as it can cause frostbite if touched directly.

While it is safe to use dry ice around food, it should never be ingested as it can cause internal frostbite.

Only use dry ice in well-ventilated areas and do not allow the concentration of carbon dioxide in the air to reach 5% or more.

Frequently asked questions about dry ice

The following guide explains the answers to some frequently asked questions about the safe use of dry ice.

Is dry ice dangerous?

Dry ice is safe to use in areas with air circulation, but can cause carbon dioxide build-up in small, confined spaces. Carbon dioxide displaces oxygen molecules, which over time can lead to suffocation. Some of the early signs of oxygen starvation are:

headache

confusion

disorientation

difficulty breathing

Bluish coloring of the skin

Because dry ice releases carbon dioxide gas, you should also avoid storing the material in an airtight container. Otherwise, gas build-up can pressurize the container and cause it to burst.

Be aware of the types of materials that interact with dry ice. Glass, ceramic, stoneware, plastic and other surfaces can crack due to the dramatic temperature difference when exposed to dry ice. It’s common to use Styrofoam coolers to transport and store dry ice because it won’t crack, is insulating, and can safely disperse carbon dioxide.

Touching dry ice without protective gear can cause frostbite. Always wear gloves when handling the material and consider moving the parts with pliers rather than touching them directly.

What is the dry ice formula?

Dry ice has only one ingredient: carbon dioxide. Technicians make dry ice by pumping liquid carbon dioxide into storage tanks, lowering the temperature to -109°F and pressurizing the substance into solid blocks or pellets.

What is the difference between dry ice and liquid nitrogen?

Liquid nitrogen is much colder than dry ice — typically between -346°F and -320.44°F — which also makes it more dangerous to handle. Because it is a liquid rather than a solid, it is also more difficult to work with in many environments and can be difficult to contain.

Liquid nitrogen is commonly used as a refrigerant due to its very low temperature, food freezing, biologics storage in dedicated freezers, and thermal grain processing in metallurgy are typical, however it is most commonly used as an efficient method of storing or transporting gaseous nitrogen used.

Although dry ice isn’t nearly as cold, it serves as a shipping method for frozen goods as it can stay cold for up to 7 days in special shipping boxes.

Dry ice is also used in the food industry to prevent spoilage during large-scale mixing or milling processes such as hamburger making. Dry ice pellets are added directly to the grinding process to keep the temperature of the ground material below the temperature range for bacterial growth, liquid nitrogen is usually too cold for these applications.

Without a doubt, dry ice makes the coolest cocktails. At minus 109 degrees Fahrenheit, the extremely cold temperatures can make it dangerous if you don’t know how to handle it. I’ve always been afraid of using dry ice, but I did a lot of research before my Haunted Mansion-themed Halloween party and I can now confidently use dry ice in cocktails for years. I was frustrated that it took me so many years to figure out how easy it is to use and manage, so I’ve put together everything I wish I knew for you. This article was updated on 01/10/21 with additional photos and information.

Can I safely use dry ice in drinks? Absolutely! Dry ice will sink to the bottom of drinks and won’t harm your drink at all. In fact, you have the most chilled cocktail of your life. What you don’t want to do is consume the dry ice in its solid form. Thankfully it sinks and stays out of the way and once it’s done smoking it’s completely gone. I still wouldn’t serve it to children who could tip a glass too far and let the solid shape touch their lips. If you want to serve dry ice to kids, there are some cool containers online that you can use to store the dry ice until it evaporates. You’re telling me I absolutely can put dry ice chunks straight into drinks? Yes you absolutely can.

How does dry ice work? Dry ice skips the liquid phase of melting and goes straight from solid to gas, as soon as it meets liquid of any kind the solid chunks of ice turn to smoke. After smoking, the dry ice has completely evaporated.

Which drinks work best? Juice-based drinks and cocktails work best. I tried dry ice in an iced coffee with milk and it looked like a science experiment, so avoid milk drinks and cocktails. I successfully put it in pure orange juice for a Halloween breakfast and it worked perfectly! I haven’t tried carbonated dry ice, but I think we should avoid it. Here are two of my dry ice cocktails featured here: Foolish Mortal, All Hallow’s Eve Martini. I really loved how the dry ice looked as it poured out of the martini glass!

Where can I buy dry ice? Many grocery stores carry dry ice. I got mine at my local Kroger. It is in a special storage case. You should pick it up by the top of the bag so you don’t touch the ice. Alternatively, you can wear latex gloves to be on the safe side.

How far in advance should I buy it? Dry ice completely evaporates within 24 hours, so it’s best to buy it as close to the party as possible. My mom kindly picked up dry ice for me two hours before my Haunted Mansion party.

How should I store it? DO NOT put it in the fridge or freezer. I know this is counterintuitive because it’s ice, but dry ice is so cold it doesn’t need (and shouldn’t) be refrigerated in any way. Dry ice releases carbon dioxide and should not be stored in an airtight container. It might explode! It is best to place in an empty ice chest (no additional ice needed) with the lid open or ajar, out of the reach of children and pets. Keep the bag sealed until just before serving. I keep the leftover dry ice pack back in the ice chest and leave it in the garage overnight. It will last longer if you just break off what you need and leave a big chunk overnight. If you have some left over the next day, add it to your morning juice! I mean honestly why not?

How should I transfer it? If your drive from the store to your house takes more than ten minutes, open your car windows. You don’t want dry ice to be in a small, enclosed space.

What supplies do I need to have on hand for my party? Make sure you have latex gloves, a hammer, pliers and a towel. Put on the gloves before working with dry ice, just to be safe. Lift the bag by the top plastic part, place it on half a towel, tear open the bag a few inches, place the other half of the towel on top, and gently break the dry ice into pieces with a hammer. I like fairly large pieces, about 2-3 inches in diameter. Tear open the bag and use tongs to place dry in your cocktail.

What can I expect when adding dry ice to a cocktail or beverage? Get the camera ready because she’ll start smoking right away! It looks best for the first 3-5 minutes or so, but will continue to fizz and smoke lightly for up to ten minutes. You can drink it while it’s still smoking and fizzing. You can see the piece of dry ice at the bottom of your glass. Out of ten cocktails, one of my friends turned to mud at the bottom of the glass. To be on the safe side, I poured water over it and threw it in the cooler to get rid of the mud. It smoked and evaporated. Remember: you don’t want to consume a solid form of dry ice.

Here’s a short video on dry ice safety: I hope you found this information helpful! With a few safe handling tips, dry ice can be a fun and fabulous addition to your party.

dry ice

background

Dry ice is frozen carbon dioxide that goes from a solid to a gaseous state without going through the liquid phase. So when used to cool food and drinks, it doesn’t leave water behind like regular ice. Dry ice can cause skin burns, should never be swallowed, and care must be taken in transportation and storage.

Security Concern Recommendations:

Dry ice can cause skin burns and should never be eaten

Dry ice can cause containers or surfaces in which it is stored to crack

Dry ice can cause an explosion if stored in a sealed container

Dry ice can cause suffocation

Storage and transport of dry ice:

Dry ice must be stored in well-ventilated locations and placed in insulated and ventilated storage areas, insulated coolers, or special coolers designed for dry ice storage. [Shortcut]

Due to the thermal expansion of dry ice (one pound of dry ice produces about 250 liters of gaseous carbon dioxide), enough gaseous carbon dioxide can be released in a sealed container to cause a pressure explosion. Dry ice should never be stored in tightly sealed equipment such as ultra-low freezers or plastic/glass containers. [Shortcut]

If transporting dry ice in a vehicle, be sure to ventilate the vehicle by keeping windows open to avoid excess carbon dioxide fumes that can cause asphyxiation. Several bartenders have reported dizziness when transporting dry ice in a closed vehicle. In at least one incident [link] people transporting dry ice died due to lack of ventilation.

Use of dry ice:

Dry ice can cause burns or frostbite. Avoid skin contact with dry ice and consider handling it with cloth or leather gloves, towels, etc.

Dry ice should never be consumed. Not only can it burn internally, but it releases gas as it transitions from a solid to a gas.

In a bar setting, dry ice will bubble and create fog when immersed in warmer liquids. However, if a customer is served a drink containing dry ice, there is a chance that the customer could swallow it. Do not serve dry ice to customers (or yourself).

Store dry ice in a well-ventilated area to minimize carbon dioxide build-up. The sublimated carbon dioxide gas sinks to low levels, replacing oxygen-rich air. This can cause suffocation if inhaled solely. Be careful when storing dry ice in a freezer and don’t stick your head in an ice chest to obtain dry ice.

Do not store dry ice in a tightly sealed container. Gas can accumulate and cause an explosion.

Ventilation is important to prevent carbon dioxide build-up. Do not store dry ice in an enclosed area such as a B. in walk-in refrigerators, refrigerators, freezers or vehicles.

Do not dispose of dry ice down a sink, toilet, or other drain.

Due to its extremely low temperature, dry ice can crack solid countertops or tiled surfaces.

Frequently Asked Questions What is dry ice? Dry ice is solid carbon dioxide (CO₂). It has the unusual property of “sublimating”, that is, going from a solid to a gas without going through a liquid phase, and hence it has earned the name dry ice. The product can only exist at -79°C and maintains this temperature through sublimation. In the UK, the CO₂ in dry ice is from a recycled source, so it doesn’t contribute to global warming. How is dry ice made? Liquid carbon dioxide (CO₂) is the source of all dry ice products. The liquid is stored at 20 bar and around -20 °C. It is released through a nozzle to 1 bar, at which point dry ice “snow” is created. This snow is compressed at approximately 1500 psi and extruded to form pellets, discs and blocks of dry ice. The CO₂ used is food safe and non-toxic, it’s the same chemical that gives drinks their fizz. Dry ice has a density of around 1.6 g/cm3, but the bulk density is around 1 g/cm3, just like water. The molecular weight of dry ice is 44.01. How do I store dry ice? Store dry ice in an insulated container – the better the insulation, the slower the rate of sublimation into CO₂ gas. The best container is the styrofoam box that the dry ice was shipped in. Do not store dry ice in an airtight or glass container. The sublimation of dry ice into CO₂ gas will cause an airtight container to expand, crack or burst. The CO₂ gas takes up about 800 times the volume of dry ice! CO₂ gas is heavier than air and sinks to lower levels, displacing air. In high concentrations, CO₂ can be deadly as a suffocating agent. For this reason, always store dry ice in a well-ventilated area—avoid unventilated spaces like basements, boat rooms, and walk-in freezers. Note: You can store dry ice in home (non-walk-in) freezers as long as the dry ice is kept in the styrofoam packaging. The dry ice releases CO₂ gas in the freezer, but there is no risk of suffocation. The freezer reduces heat transfer into the box and extends the life of the ice. However, do not store dry ice in walk-in freezers due to the risk of CO₂ build-up, which can lead to suffocation if the freezer is not used regularly. Some surfaces that remain in direct contact with dry ice can be damaged by the extreme cold. Adhesives can become brittle and break. Therefore, please do not bring dry ice into contact with kitchen tiles or other cold-sensitive surfaces. Is dry ice safe? Provided safety guidelines are followed, dry ice is safe – we ask our customers to comply with BCGA guidelines as a condition of sale. Please read our dry ice safety and guidelines for more information. What is dry ice fog? When dry ice is added to warm water, a dense white fog is created immediately. The white mist is an aerosol of tiny water droplets, just like naturally generated mist. What happens is that the very cold dry ice sublimates from the solid to the gaseous phase and bubbles through the water. In the process, the CO₂ gas leaves the water tank, above which there is a considerable amount of humid air. The cold CO₂ gas condenses water molecules in the air above the container, resulting in the formation of tiny water droplets so small that they remain suspended with the gas. The only difference between natural fog and dry ice fog is the presence of gaseous CO₂ interspersed with the water droplets. CO₂ gas is heavier than air, so it tends to carry the white mist towards the ground, creating cool effects! The mist covers the ground, rolling down stairs and swirling as you walk through it. It does not rise in beams of light like glycol-type foggers, and does not create a fine mist in the air like haze fog. Dry ice fog has no odor, contains no chemicals and leaves no oily residue. How do I make dry ice fog? Consider using a fog generator – the next question “How is a dry ice fogger operated?” If you want to cover a large area like a dance floor you will need 20kg of dry ice which will last 8-10 minutes. Put dry ice in a container with hot water (50 °C) and the fog effect will start immediately. The mist effect can be stopped if too much dry ice has been added to the water, cooling (and ultimately freezing) the water and reducing the humidity level above the container. To maximize the mist effect you must use warm/hot water. If you want the mist effect to last for a longer period of time, consider adding a heat source to keep the water warm – the container could be a rice cooker or a slow cooker on the lowest heat setting. Be careful – if you use the heater on a high setting, thermal currents will send the mist airborne and spoil the effect. Candles won’t work as the CO₂ will put out the flame, after all CO₂ is used in fire extinguishers! How is a dry ice fogger operated? The fog machine is filled with water and heated with its built-in heating elements. When the water has reached operating temperature (two to three hours), the ice chamber in the machine is loaded, when fog is needed, the pump is turned on and hot water is pumped into the ice chamber, creating fog immediately. The fan is switched on and the fog is blown onto the stage via an exhaust air hose. How do I order dry ice? You can order dry ice packs online by clicking on the buy dry ice pellets link. Our standard delivery days are Tuesday to Friday. We deliver on Mondays and Saturdays for £10. Saturday options are available online. Monday deliveries are by special arrangement – please email [email protected] or call 020 3432 9412 with your request and we will process your order for you. How long does dry ice last? It depends on! 10kg can be consumed in minutes when added to sufficient hot water for large scale effects. However, for smaller, more subtle effects, the dry ice can last for hours. We ship dry ice in thick styrofoam boxes and the ice will last 3-4 days depending on how you store the ice. We recommend keeping the ice cream unopened in the packaging until needed and storing the box in a safe, cold place. Once ice has been used, place the lid on the remaining product and store in a cold place. Can we put dry ice in drinks? Dry ice should never be put in the mouth or swallowed. Therefore, as a general rule, dry ice should never be added to beverages to avoid such a risk. We have developed a product called Chillistick that allows dry ice to be added to drinks to create a safety barrier between the drinker and the dry ice, allowing for great smoky effects while you enjoy a drink safely. When dry ice is loaded into the Chillistick, much of the gas bubbles up to the surface, creating the much-loved mist. A small amount of gas will dissolve in the liquid to create carbon dioxide and effectively carbonate the drink, but not enough to cause fizz. The slight carbonation effect is enough to tingle on the tongue and produce a slightly bitter taste like that found in popular sodas. Ironically, dry ice doesn’t mix well with carbonated soft drinks or beer. The powerful effervescent action essentially does not decarbonate the beverage, leaving the beverage “flat”. Chillisticks are therefore best used with non-carbonated cocktails and fruit drinks, punch etc. Dry ice cools beverages and does not dilute beverages because it sublimates like traditional water ice. It’s cold enough to chill drinks without ice. Therefore, dry ice will not water down or dilute beverages. The fog effect varies depending on the temperature of the drink. The colder the liquid, the slower the dry ice will dissolve, see our fogging section. A hot drink can produce spectacular results as the dry ice dissolves quickly. Typically, the fog effect can last 3 to 5 minutes. How much dry ice do I need? Our small 4 kg pack is ideal for presenting small items such as cakes, food and drinks. Please note that when you are looking for a subtle effect to enhance a food/wine presentation, less is definitely more! If you want to create some big smoke effects for your guests then you will need the 10kg pack and if you have a lot of space and want to create something special then multiples of these are worth considering. As a rough guide, 20kg of dry ice can create fog for between eight and 10 minutes, creating a dense blanket of fog. Where do you ship dry ice to? We can ship dry ice nationwide next day to get to you Tuesday through Friday. We can also arrange Saturday services and timed arrivals by special arrangement. What kind of ice cream do you supply? We supply 9mm food grade pellets. Do you ship frozen goods? Yes, we offer a full service for frozen or refrigerated shipping including collection, document creation and small-volume shipping nationwide. If you would like any further information please do not hesitate to contact the team on 020 3432 9412. Use of dry ice in the Chillistick The Chillistick allows for the safe use of dry ice in drinks and cocktails. The Chillistick is filled with dry ice and then dipped into beverages when it instantly starts fizzing, creating a dense mist of water that looks cool in every way. The white mist is made up of tiny water droplets – just like mists that form in nature. The mist diffuses the drink’s natural scent, allowing you to smell the drink before you taste it! Please read safety instructions for safe use of dry ice. Open the dry ice box and cut the thick poly bag with scissors or a knife. We recommend wearing gloves when handling dry ice. Using a scoop or gloved hand, scoop out a handful of dry ice and select one or two pellets that are 1/4 inch or longer. If using gloves supplied with the kit, place both gloves on one hand – the air gap between the layers provides insulation. NOTE: You will notice that there are some small pieces of ice and some dry ice dust. This is normal. These smaller pieces keep the larger pieces in good condition. So put that dust back in the box and close the lid. Hold the Chillistick by the base of the handle and, wearing gloves, gently place a piece of dry ice onto the scoop end of the Chillistick. Press the ice with a finger so that the plastic safety valve in the Chillistick opens. Using a stir stick or glass rod, push the ice through the valve and into the body of the Chillistick. NOTE: The valve will be a bit stiff the first time you use the Chillistick, you may find it easier to loosen the valve with a stir stick or pinky finger before filling with ice. To check that the ice is fixed in the Chillistick, the rounded end of the stirrer will engage the valve and it will be possible to hold the entire assembly by the stirrer. Pull out the stir stick and use it. You can prepare Chillisticks up to 45 minutes before serving and in this case store the loaded Chillisticks in the dry ice box. With a little practice it is possible to load the Chillistick in about 5 – 10 seconds. Please watch the Chillistick instruction video. To create spectacular misting effects to enhance the back of the bar area or when serving food, we recommend using a tall vessel to minimize the footprint: fill the vessel with warm to hot water and add about half a cup of dry ice added. The mist flows down the pitcher and over the surrounding area. Placing the jar under a spotlight maximizes the effect, which lasts up to 5 minutes. The warmer the water, the more spectacular the mist effect will be; As the water in the vessel gets colder, the smoke effect decreases. If you’re serving food, you might want to consider adding essential oils to the water that add flavor to the food – vanilla for desserts, for example. Your guests will smell these complimentary flavors, enhancing the experience. Please contact us to discuss bespoke smoke designs.

Frozen vinegar in baking soda (left) and frozen baking soda in vinegar (right).

Scientific experiment with frozen baking soda / bicarbonate made from baking soda and vinegar

This frozen baking soda/bicarbonate science experiment made from baking soda and vinegar is a fun way for kids to see how temperature affects chemical reactions. When I make this with my kids, I add food coloring (or natural pH indicators) so they can see the colors mix along with the chemical reaction.

Older kids can do several science experiments with baking soda/baking soda and vinegar to compare how freezing vinegar or freezing baking soda changes the reaction. When comparing your reaction, it is recommended that children use the same amount of baking soda and vinegar each time.

What you need

Baking Powder / Baking Soda

Vinegar

ice cube tray(s)

Baking tray / ceramic tray(s)

Using a freezer

measuring cup

To do this, you need to freeze vinegar (optionally mixed with food coloring) in ice cube trays. To freeze baking soda, mix it with some water (and food coloring) and pour it into ice cube trays before freezing them. If you’re doing this as a comparison experiment, be sure to measure out the baking soda and vinegar so that you’re comparing the same amounts each time.

*Above we added frozen vinegar to a bowl of baking soda with a little cabbage juice (natural pH indicator).

Questions to ask

What happens when you mix baking soda and vinegar?

Is there a difference if you freeze vinegar and add it to baking soda? What if you freeze baking soda and add vinegar to it? Why do you think it happened?

How does freezing change the reaction? How does it affect how quickly they respond / how long it takes them to respond?

Which one did you like the most? Why?

Why do you think they do different things?

What did you learn?

In the video above, we placed frozen baking soda mixed with turmeric (a natural pH indicator) in a bowl of vinegar.

In the video above, we placed frozen baking soda mixed with red cabbage (a natural pH indicator) in a bowl of vinegar.

What they get from experimenting with baking soda/baking soda and vinegar

Conducting a science experiment with frozen baking soda/baking soda and vinegar is a fun, hands-on way for kids to compare the reactions of baking soda and vinegar. Research shows that people learn best (at least for long-term memory) when they learn through hands-on experience (Hearns, Miller, & Nelson, 2009; Hillman, 2011; Ferri, BH, Ferri, AA, Majerich, D.M., Madden, A.G., 2016). It is also an opportunity for children to develop scientific thinking. In addition, inquiry-based learning promotes children’s curiosity and desire to learn, which also benefits the learning process (Ambrose et al. 2010; Froyd 2008; Prince & Felder, 2007; Springer, Stanne & Donovan, 1999).

There are also opportunities for children to develop science skills such as forecasting, observation, recording (including data logging) and sharing/presenting their ideas. Kids can also draw or write to record their observations, which can be good motivation for kids who don’t want to write.

Go on

Allow the children to think of another experiment to try. This will further support inquiry-based learning.

Your freezer can extend the shelf life of your favorite baking ingredients.

Your pantry keeps many of your most important cooking ingredients safe and organized, but when it comes to baking ingredients, there’s another place in your home that can do it: the freezer. Storing baking utensils in your freezer is a great way to extend their shelf life and prevent bugs from getting into your prized ingredients. Here are a few baking supplies you can store in your freezer (and here are a few products to help with freezer storage).

Claire Krieger / Taste of Home

all purpose flour

Duration: Two years

How to store flour: Place in an airtight container and freeze.

Flour is necessary for almost every baking recipe, from brownies to cakes to scones. Unfortunately, we’re not the only ones who find it delicious. All flours are attractive to pantry bugs like mites and moths. Storing your flour in the freezer keeps it away from bugs. Plus, it keeps your flour longer.

butter

Duration: Up to a year

How to store butter: Leave the butter sticks in their original packaging, then place them in the freezer.

Butter contains oils, which means it will go bad faster than many of the other baking ingredients on this list. Luckily, you can extend the shelf life of your butter by putting it in the freezer. Buttersticks should keep frozen for up to a year. Bonus: Freezing your butter gives you a head start when working with pastries.

Fresh fruit

Duration: Up to a year

How to store fresh fruit: Place the berries in a resealable plastic bag and freeze. You can freeze bananas whole.

Fruit can be added to bread, muffins, pastries, whatever. But if you buy your fruit in bulk or want to store fruit beyond the season, you can freeze them in freezer-safe bags for up to a year.

nuts

Duration: Two years

How to store nuts: Store unopened bags in the freezer or transfer opened packages to freezer-safe bags or containers.

Nuts are high in oils, which spoil quickly if left at room temperature for long periods (think several months). Prevent nuts from going rancid and keep them tasting fresh by popping them in the freezer.

Yeast

Duration: Two years

How to store baking soda: keep it in its original packaging and place it in the freezer.

Yeast is one of the most important ingredients if you want to bake your own bread at home. Inactive yeast can lead to flat breads and sad hearts, but storing your yeast in the freezer can extend its shelf life by up to six months.

dried fruit

Duration: 18 months

How to store dried fruit: keep them in their original bags, then place them in the freezer. You can also keep them in the pantry where they will last for about a year.

Like fresh fruit, dried fruit is a great addition to many of your baking staples, from waffles to scones. Place bags of dried fruit in the freezer, seal with a vacuum sealer or a rubber band, and store for up to 18 months.

eggs

How Long They Last: Up to a year

How to store eggs: Do not store eggs in their shells in the freezer. Instead, crack them open, beat them up, and store them in an airtight container.

Believe it or not, you can freeze eggs! Once beaten, you can freeze eggs. Thaw and use as usual. You can freeze individual eggs for easy baking (or if you’re freezing multiple, remember that three tablespoons of beaten eggs equals one egg). Just make sure you use them the same day you thaw them.

baking soda

How long it lasts: Forever

How to store baking soda: keep it in its box and place it in the freezer. Once opened keep in an airtight container and store in the freezer.

Baking soda has so many uses around the house, but if you’re using this ingredient primarily for baking, store it in an airtight container in the freezer so it doesn’t absorb odors from other foods.

almond flour

Duration: Two years

How to Store Almond Flour: Store in an airtight bag or container.

Almond flour is a necessity if you love making macarons at home. Storing almond flour in the freezer keeps it fresh, keeps bugs out, and prevents clumping, which is a nightmare when making macarons.

semolina flour

Duration: Two years

How to Store Semolina Flour: Store in an airtight bag or container.

Do you love the taste of homemade pasta? You need to stock up on semolina flour, a special flour made from durum wheat. It’s perfect for making your own pasta or dusting the outside of homemade pizza dough.

milk

Duration: Six months

How to store milk: Freeze milk in an airtight container that will give it room to expand.

Yes, you can freeze milk! The key to freezing milk is pouring enough to allow the liquid to expand in the freezer. You can transfer to mason jars or airtight containers that allow for expansion, but make sure you leave plenty of room. Our favorite way to freeze milk? Pop it in ice cube trays. This way you only have to defrost what you need instead of a large container full.

whipped cream

Duration: Up to four months

How to Store Whipped Cream: Pour whipped cream into freezer-safe containers and store. Alternatively, you can pour whipped cream into ice cube trays and freeze.

Whipped cream is great for whipped cream and cream-based desserts. You can freeze whipped cream for several months past the expiration date, but make sure you freeze it in a container that will allow for expansion. Don’t keep it in its paper container as it will make a big mess when thawed.

There are some baking ingredients that are better left in the pantry (like baking powder and chocolate), but for the most part, you can extend the shelf life of your favorite baking ingredients by storing them properly in the freezer. Just make sure you thaw them slowly and carefully before use!
