How long should a fidget spinner spin for?
With a starting angular velocity of 140 rad/s (a little bit faster than the example data above), it would spin for 104 seconds. If you want it to spin even longer, then just spin it faster. Doubling the starting angular speed will double the time.
What’s the longest time a fidget spinner spin?
The accomplishment, a team effort by employees at MinebeaMitsumi Inc., was won by Takayuki Ishikawa. The record-setting time: 24 minutes and 46.34 seconds.
How fast can a fidget spinner spin?
This gives a time of 0.14 seconds per revolution.
How fast is the fastest fidget spinner?
In the end, Takayuki Ishikawa came out on top, managing to keep a specially-designed fidget toy turning for a staggering 24 min 46.34 sec – beating the previous record by almost 20 minutes.
Why does a fidget spinner spin so long?
Fidget spinners are essentially low-friction ball bearings. That’s it. When two objects press against one another, friction prevents them from sliding smoothly. If you try to slide a block of wood across a wooden floor, you’ll find that it eventually stops sliding thanks to the friction between these two objects.

But how do they work and more importantly, how can you make them spin longer and faster? Dive into physics – your high school nightmare and your key to wriggling weirdo nirvana.
What is a fidget spinner?
Fidget spinners are essentially low-friction ball bearings. That’s it.
When two objects press against each other, friction prevents them from sliding smoothly. If you try to slide a block of wood across a wooden floor, you’ll find that it eventually stops sliding thanks to the friction between these two objects. But if you roll a wooden ball across the same floor, even though wood is still hitting wood, the ball will meander along while the friction pauses. This is because rolling friction (a misnomer) is much weaker than ordinary sliding friction, as the contact area between the ball and the ground is relatively insignificant.
Ball bearings use this neat physics trick to create incredibly low-friction surfaces. Jet engine shafts, watch mechanisms and skateboard wheels are all known to have ball bearings of various grades and coefficients of friction.
Most fidget spinners have a ball bearing right in the center of the toy that you hold while spinning. The center consists of several tiny spheres sandwiched between two circular channels called the “inner barrel” and “outer barrel”. Without the balls, the races would only turn against each other for a few moments, until sliding friction declared victory. But thanks to the balls between their surfaces, the races can rotate much longer and are subject only to rolling friction.
How can I make my fidget spinner run longer?
The short answer is: with a friction-free surface. Unfortunately, without super-liquid helium or some nanotech know-how, you’re unlikely to be able to pull this off for your wriggling needs.
This leaves us with strategies to reduce friction within the ball bearing. A simple way is to lubricate the bearing and remove dirt that can increase friction between the races. When designing your own fidget spinner, consider less conventional materials. For example, the friction between ceramic and steel is far lower than with steel on steel. That means two steel races centered around ceramic balls could seriously up your fidget game.
How long can I keep my Fidget Spinner running?
That depends on the angular velocity you started with, writes Rhett Allain, a physics professor at Southeastern Louisiana University, in WIRED. Allain placed his own fidget spinner (no one’s sure) under a laser to calculate the rate of change of angular position over time (similar to figuring out the speed you’re going by calculating how many miles you’re going per hour). As the spinner slows down over time, Allain also had to calculate angular acceleration, or the fairly constant rate at which the fidget spinner slows toward the inevitable.
Angular acceleration (α) can also be calculated by dividing the change in angular velocity (Δ⍵) by the change in time (Δt), which sounds difficult, but it’s essentially the same as telling a driver that he to calculate its acceleration by dividing the current speed of the car by that of a minute ago. A little muscle power and math yields this handy equation:
α = Δ⍵ / Δt
Thanks to Allain’s laser, we now know that a good spin can get us an angular velocity of about 140 radians per second with an angular acceleration of about -1.346 radians per second (the acceleration is negative because the fidget spinner is slowing down, or decelerating). Plug in these numbers and you will find that Δt = 104.011. That’s 104 seconds of glorious spin time.
Admittedly, without a laser, industrial-grade materials, and a physicist, it might be difficult to test any of these ideas yourself. But it’s guaranteed to make you a hit with your kids. Nice angular velocity son, but you have to work on that high negative angular acceleration.
Works every time.

A three-lobed fidget spinner with Canada maple leaf designs
A fidget spinner is a toy consisting of a ball bearing in the center of a multi-lobed (usually two or three) flat metal or plastic structure designed to spin along its axis under pressure. Fidget spinners became a trending toy in 2017, although similar devices were invented back in 1993.[1]
The toy was advertised to help people who have trouble concentrating or those who need to fidget to relieve nervous energy, anxiety or mental stress. There are claims that a fidget spinner can help calm people with anxiety or neurodivergences like ADHD and autism.[2] However, as of May 2017, there is no scientific evidence that they are effective for treating ADHD.[3][4]
Development [edit]
In October 2016,[5] inspired by the Fidget Cube Kickstarter campaign,[6] former Android app developer,[7] Allan Maman[8][9] used his Byram Hills High’s 3D printers School to make Fidget360[10 ] later with Cooper Weiss.[11][12] Her physics teacher was Eric Savino.[13][14] The ceramic ball bearing R188 (1/4 x 1/2 x 3/16 inch) with ceramic balls and ceramic rings had longer turning times.[15]
In an interview that appeared on NPR on May 4, 2017, Scott McCoskery described how he invented a rotating metal device, a torqbar,[16][17] in 2014 to deal with his own fidgeting in IT meetings and conference calls .[18] In response to requests from an online community, he began selling the device online.[18]
Popularity and usage[ edit ]
With the rapid rise in popularity of fidget spinners in 2017, many children and teenagers began using them at school, and some schools also reported students swapping and selling the spinner toys.[19][20][21]
Because of their frequent use by schoolchildren, many school districts have banned the toy.[22][23] Some teachers argued that the crackers distracted students from their schoolwork.[19] According to a survey conducted by Alexi Roy and published in May 2017, 32% of America’s top 200 public and private high schools had banned crackpots on campus.[24]
As fidget spinners rose in popularity in 2017, many publications in the popular press debated the marketing claims made about them for people with ADHD, autism, or anxiety.[4][22][23] However, there is no scientific evidence that fidget spinners are an effective treatment for children with ADHD.[3][4][25] They quickly declined in popularity and sales after peaking in May 2017.[26]
Patent status[ edit ]
As of 2017, the patent status of the various fidget spinners on the market was unclear.[27] Catherine Hettinger, a chemical engineer by training, was originally credited with inventing the fidget spinner by some news outlets, including The Guardian,[22] The New York Times[23] and New York Post.[28] Hettinger filed a patent application for a “spinning toy”[29] in 1993 and a patent was granted, but Hettinger lapsed the patent in 2005 after being unable to find a commercial partner.[27][22] However, a May 2017 Bloomberg News article indicated that Hettinger was not the inventor of the fidget spinner, and Hettinger concurred.[27]

Why is my fidget spinner slowing down?
Dust and grime – Oils from your fingers and plain old dust in the air will eventually make their way into your bearings and start to slow down your spinner. To slow this down, keep your spinner in a case or bag when not in use. You can also clean your spinner by using rubbing alcohol, a toothbrush, and a hairdryer.

How to clean a fidget spinner
Fidget spinners are a fun fidget toy and as with anything in life, care depends on how long the fun lasts. Below I have listed top tips for cleaning fidget spinner bearings and how to clean fidget spinners.
When did fidget spinners come out?
Catherine Hettinger, a chemical engineer by training, is the first person who came up with this spinning toy in 1993. Catherine came up with the idea for this spinning toy to help children cope with their emotions and in turn the “spinning toy” was created.

The history of the fidget spinners
In the 1990s, fidget spinners were made with small bearings and various materials such as copper, brass, stainless steel and even plastic. These small bearings helped the fidget spinner spin in directions fairly quickly and were believed to have a health benefit for children suffering from anxiety or ADHD-like symptoms. Catherine Hettinger, a chemical engineer by training, is the first person to invent this spinning toy in 1993.
Catherine came up with the idea for this spinning toy to help children manage their emotions and that’s how the ‘spinning toy’ was born. While this may have been Catherine’s guiding principle, some say the true vision stemmed from her own health issues, which made it impossible for her to play with her daughter in the traditional way. Originally sold at Florida art fairs and made at her home, Catherine was in fact the first person to make fidget spinners.
While there are some arguments that the history of the Fidget Spinners bears no direct relation to the spinning toy that Catherine Hettinger patented in 1993 for today’s Fidget Spinner, some could argue that she really was the original brains behind this currently popular toy . Since the patent on this type of toy is much debated as the wording of the patent is unclear, there is no doubt that the fidget spinner toy has been around much longer than the average consumer realizes.
This toy is designed to help children and adults who suffer from wriggling symptoms that usually stem from anxiety, autism or ADHD. While some argue that fidget spinners have no proven health benefits, there are parents around the world who firmly believe that these fidget spinners have truly changed the lives of their fidgety kids.

How small is the world’s smallest fidget spinner?
Measuring at just 5.09 mm (0.20 in) long, MinebeaMitsumi Inc. from Minato, Tokyo, has built the world’s Smallest fidget spinner – and it will easily fit on your fingertip.
How fast does a fidget spinner spin? – Damien Kee
However, a company in Japan has developed one that is much smaller than the average fidget spinner you see in stores.
At just 5.09mm (0.20 inches) long, MinebeaMitsumi Inc. of Minato, Tokyo built the world’s smallest fidget spinner – and it fits easily on your fingertip.
Yes
The spinner was built using MinebeaMitsumi Inc’s existing record-breaking product, the smallest commercially available steel ball bearing, itself measuring just 1.499mm, and weighs a featherweight 0.027g (0.00095oz).
“Toy finger spinners are not yet perfect from a professional’s point of view. We can feel the quality when we touch it,” said project leader Shigeru None.
“We wanted to make a super high quality product that has ‘the smallest, the longest spin and the smoothest’ features. We wanted to prove the precision of our bearing by developing a fidget spinner that spins the longest.”
A team of eight worked on the tiny spinner for two months.
The radius from the center of the spinner to the edge of a lobe is 3.03 mm (0.11 in), while the thickness, including the knob, is 1.70 mm (0.06 in) and 0.63 mm (0.02 inches) without amounts and helps to present the company’s attitude to customers.
MinebeaMitsumi Inc. also set a new record for longest time spinning a fidget spinner on a finger, with employee Takayuki Ishikawa clocking a time of 24 minutes and 46.34 seconds.
Mitsubishi Precision Co. Ltd employees put together the Fidget Spinner, based on MinebeaMitsumi Inc. ball bearings, with a heavier design on the outside and a lighter center section – with 50 people spending six months developing and perfecting it .
Yes
The Fidget Spinner can be bought but will cost you 49,800 yen (that’s $450.19 or £324.70).
“By integrating technologies used for space satellites, we were able to realize smoothness and mind-blowing rotation time that we have never seen before. We have also applied technologies to manufacture bearings used for aircraft and wheels and rings. We use materials with the highest strength among aluminum alloys and the highest quality brass, so wheels and rings are consistently thinner and lighter than conventional ones” – Shigeru None.
For the record, the aluminum and brass device could only be rotated once to trigger it early in the attempt – but Takayuki managed to keep it going and beat the previous record by more than 20 minutes.
“We hope that from this spinner you can feel the smooth feel of rotating precision devices quietly spinning through your fingertips in space,” added Mr. None.
“Even component manufacturers like us have proven that they can set the record. It’s really a pleasure.”
“I hope that young engineers, salespeople and sales technicians will be proud to be involved in the precision machining of machine parts. you can reach the top.”

There are many fidget spinners on the market, ranging from cheap plastic toys that are primarily used as a distraction, to expensive ones with real moving parts. In this article, we compile the top 10 most expensive fidget spinners in the world.
What is Fidget Spinner?
Once upon a time there was no fidget spinner, but some inventor had a brilliant idea. He took a ball bearing, chopped off its axle and attached a fidget spinner to the end. And it was good. Or so they say. But lately people have realized that the fidget spinner is a junk item so they started making them out of more durable materials like metal. Today, the most expensive fidget spinners can sell for many hundreds of dollars and are often made by companies that also make expensive products.
The Fidget Spinner is a simple toy that has become an unusual sensation. The toy consists of a small body with a bearing in the middle. The bearing is then spun around and around in a circle, causing the body to rotate in place. Once a certain speed is reached, the bearing is stopped and the body continues to be rotated by the centrifugal force of the bearing.
How does a fidget spinner work?
Fidget spinners are incredibly popular. But many people still don’t understand how they work or how to use them.
The Fidget Spinner is a toy consisting of a two or three pronged design that can be spun between the user’s fingers. Made of metal or plastic, the toy is designed to spin indefinitely with little effort and has been compared to a stress-relieving toy resembling a stress ball.

Explanation A:
(* The word “pair” is synonymous with the words “torque” and “moment” – I like the word “pair” because it conjures up the idea of two forces as shown in the picture. A pair is simple any pair of equal and nearly opposite forces acting to turn something around.)
gyro effect:
11. More precisely, “the angular momentum changes in the direction of the adjacent pair”. Angular momentum is a measure of how fast the rotor is spinning. Referring to the diagram, the spin axis (angular momentum) is the black arrow and responds to the applied pair (green arrow) by changing in that direction (red arrow) to get a new spin axis (blue) and that change in Direction is called “precession” (orange).
These “arrows” are called “vectors,” but that doesn’t matter. To find out that the arrow refers to the direction of rotation, just point along the arrow and then move your finger clockwise. All of this has an important result – you get slower precession when the spin is fast or when the pair is small. Because the smaller the pair or the larger the spin (angular momentum), the smaller the change in spin direction (red arrow).
see animations.
[Note: This is exactly analogous to the way velocity changes in circular motion: a force in the direction of motion causes an object to speed up or slow down, while a force at right angles to the direction of motion changes the direction of travel. The moon, for example, moves around the earth at a constant speed, but its direction of movement is constantly changing due to the earth’s gravity.]There’s a pretty nice video here showing how a top always points in a constant direction. More gyro links can be found here.
Statement B (less technical):
The minimum spin speed (in revolutions per second) for a typical stable gyroscope is approximately equal to √g/a, where g=9.81 m/s2 and a is the radius of the gyroscope. That’s about 10 revolutions per second for a typical “inflatable” toy top, like the one shown in the image at the top of the page.

What is the purpose of fidget spinners?
Fidget spinners are advertised to increase concentration and attention to academic tasks. Past research suggests that hyperactive movements, such as fidgeting, improve performance on attention tasks in children with attention-deficit/hyperactivity disorder (ADHD).
How fast does a fidget spinner spin? – Damien Kee
In just a few short months, fidget spinners have captured the attention of millions of children, parents, educators and pediatricians. Fidget spinners, handheld toys designed to spin freely in your hand, have become a source of entertainment for consumers of all ages. Despite a lack of scientific evidence, toy marketers have touted the benefits of fidget spinners for children with attention-deficit/hyperactivity disorder and other disorders (e.g., autism, anxiety, sensory issues). Parents are encouraged by these purported benefits to buy fidget spinners to improve their child’s concentration and reduce stress.
Current Findings
While fidget spinners are a recent phenomenon, existing therapy toys (eg, sensory playdough) have been used by occupational therapists for similar reasons, with comparatively little research supporting these claims. The purpose of this review is to search the literature on sensory toys and examine educator/professional reported concerns and medical side effects of using fidget spinners.
summary
Due to the recent surge in popularity, fidget spinners and other self-adjusting occupational therapy toys have yet to undergo rigorous scientific research. Therefore, their purported benefits remain scientifically unfounded. Pediatricians should be aware of the potential choking hazards with this new fad and inform parents that peer-reviewed studies do not support the beneficial claims.

Want to Know How Long a Fidget Spinner Spins? Get a Laser and Some Physics
Fidget spinners are the new Rubik’s Cube. Or maybe the new Tamagotchi. Or…I don’t know. Choose your fad. You see these toys, ostensibly designed to help children focus fidgets, everywhere now. Serious. Everywhere, everywhere, everywhere. A fidget spinner is basically a small bearing mounted in a piece of plastic or other material. You hold it and turn it. I think it’s kind of amusing.
Now to my question: how much longer will it spin? This of course depends on the initial angular velocity. Now to find angular velocity… oh wait. Perhaps I should discuss basic rotational kinematics first. Suppose I have some rotating object. Like a bicycle wheel for example. I can determine the angular position at any point. I will call this θ.
If the object continues to rotate so that θ changes, I can describe the rate of that change in terms of angular velocity with the symbol ω. I define the average angular velocity as:
Yes, that looks a lot like the definition of linear velocity. But what if that spinning object slows down (or speeds up)? The change in angular velocity can be described by the angular acceleration with the symbol α.
Knowing the starting angular velocity and assuming a ending angular velocity of zero radians per second, I can calculate the spin time:
All I need is the angular acceleration – assuming it stays constant as the spinner slows down. I could calculate angular acceleration from the change in angular velocity, but that’s not that easy to measure. The spinner is moving too fast to get a good video of its movement, so I’m going to use a laser in a rig I’m building to measure the change in angular velocity.
Basically, the laser shines on a light sensor. As the spinner spins, it will occasionally block the sensor and interrupt the laser. By measuring the values from the light sensor, I determine the spin rate. But that creates a few problems. First, the rate of light change and the rate of rotation are different because the three “lobes” in the spinner create multiple orifices with each rotation. Second, the spinner spins for a considerable amount of time, so it would be difficult to analyze everything at once.
This is what some of this light data looks like.
Content This content may also be displayed on the website from which it originated.
Now for the fun trick. Instead of looking at a giant light-time plot (the full data is over 2 minutes long), I’m going to graph the Fourier transform of this data. What does that even mean? Suppose this data consists of many different trigonometry functions (like sine and cosine) with different frequencies (which is essentially the case). These trigger functions have different amplitudes. So the Fourier transform shows the amplitude of different frequencies, allowing you to determine the vibration frequency.
If I select a small portion of the laser data at the beginning of the run, I get the following Fourier transform:
The longest fidget spinner spin ever + the world’s smallest fidget spinner
A wheel-shaped fidget spinner specially made by 50 Mitsubishi employees over the course of six months set a Guinness World Record for the longest time it takes to spin a fidget spinner with one hand. The achievement, a team effort by MinebeaMitsumi Inc. employees, was won by Takayuki Ishikawa. The record time: 24 minutes and 46.34 seconds. From project leader Shigeru None on Guinness:
“By integrating technologies used for space satellites, we were able to realize smoothness and mind-blowing rotation time that we have never seen before. We have also applied technologies to manufacture bearings used for aircraft and wheels and rings. We use materials with the highest strength among aluminum alloys and the highest quality brass, so wheels and rings are significantly thinner and lighter than conventional ones.”
MinebeaMitsumi manufactures motors, sensors, and other products, including the ball bearings used in fidget spinners. The price of the custom-made: $450.19 or 49,800 yen.
Eight employees from MinebeaMitsumi also spent two months developing The World’s Smallest Fidget Spinner. It is 5.09 millimeters (0.2 inches) wide.

How fast does a fidget spinner spin? – Damien Kee
In this tutorial I will show you how to use the data logging features of LEGO MINDSTORMS EV3 to measure how fast a fidget spinner is spinning.
I use a color sensor in reflected light mode positioned over one of the spinner’s lobes. Pointing the sensor directly at the table will give a strong reflected light reading. However, when one of the spinner’s lobes passes under the color sensor, the reflected light readings change. By measuring the time between each lobe passing the sensor (and considering that there are three lobes), the spinner RPM can be calculated.
I set the experiment to run for 10 seconds and take 1000 samples per second. The spinner is moving pretty fast, so we want to collect as much data as possible.
After running the experiment, we upload the data and get the following:
If we zoom in on the data, we can clearly see the spinner’s lobes as they pass under the color sensor.
The first part is before we get the spinner spinning. By zooming in on some data, we can clearly see how the spinner reflects different amounts of light depending on what’s directly under the color sensor. I was surprised how clearly you can see the different parts of the spinner. You can clearly see the silver parts of the bearing sandwiched between the black molded plastic.

By measuring the time between any two common positions on the chart, you can calculate how fast a lobe of the spinner will pass. Considering that my spinner has 3 lobes, you can calculate the RPM of the spinner at different times.
Using the analysis tool, we can measure how long it takes the spinner to spin. You’ll notice that I took the first “high” part of the chart where the spinner sees the white table, and then again the fourth “high” part. This is because there are 3 lobes of the spinner.
You can see that the beginning of my segment crosses the x-axis at 2.16 seconds and ends at 2.30 seconds. This gives a time of 0.14 seconds per revolution.
To convert to revolutions per minute (rpm), divide 60 by the time it takes for 1 revolution. 60/ 0.14 = 428 rpm.
I calculated the speed at the start and again about 8 seconds after it started spinning. My spinner went from 428 rpm to 215 rpm during this time.
This would be a great experiment in class as it would be possible to see the relative slowdown between different types of spinners.
