Fidget Spinners: What They Are, How They Work and Why the Controversy

This season's hottest toy is marketed as an antidote for Attention Deficit Hyperactivity Disorder (ADHD), anxiety and autism , promises greater concentration for people with those conditions, plus an opportunity to "bring out that creative genius lying deep within you." — but it's also being banned in classrooms across the country.

'Fidget spinners' are small, ball-bearing devices that one can rotate between one's fingers. The momentum of the toy provides a pleasing sensory experience, according to user reviews, while the challenge of tossing, transferring and twirling the spinners has spawned an entire universe of instructional YouTube videos.

Ball bearings are key to this spinning toy. To understand why, try this: Slide a block of wood or other material across the floor. Then do the same with a marble. The marble goes farther because the friction associated with rolling motion is typically less than so-called sliding friction.

This same principle can be applied to the spinners. At the center, and on each of the three "wings" of the spinner, is a bearing race, which is a circular channel around which tiny balls roll with low friction, To get any object to rotate, you need to exert a twisting force, known as torque, on it. In a fidget spinner, you hold the center of one ball bearing, the outer bearing race spins around, and the outer parts of the fidget spin with the outer bearing race. One flick of the fidget with a finger or a rapid twist of the wrist sets the fidget in motion, and it keeps going because of the low friction.

And when it comes to spinning, shape matters. If you put the ball bearing at the center of a disk, you must start the spin by pushing on the outer part, owing to the fact that the object's center of mass would be at the center. (The center of mass is the point at which you can balance an object, like the pivot point of a seesaw.) However, if the object has protrusions so the ball bearing is not at the center of mass, you can start it spinning with a flick of your wrist. 

Think of the ball bearing at one end of a short, thick tongue depressor. Hold the bearing between your thumb and forefinger and let the depressor hang down. Move your hand forward parallel to the floor, then stop suddenly, and the stick will flip around in a circle.

Regardless of their usefulness in keeping kids' distracted brains focused, fidget spinners have sparked a conversation about attention spans in kids and how to help the little ones focus, experts told Live Science. For instance, though there isn't a lot of data supporting the idea that kids have less focus today than in the past, some research does suggest attention spans have decreased as multitasking has increased with the digital age, one expert said. There are various methods for bringing kids' focus back to the lesson at hand, psychologists say, including fidgeting devices, activity breaks and the simple removal of extra distractions. The devices may also teach kids some physics, or at least ball bearings.

There's no doubt that toys that allow kids to fidget can benefit kids with autism. Occupational therapists often use sensory toys like tactile discs, Koosh balls and even putties or clays to soothe kids who have sensory-processing issues. Similarly, research has shown that movement can help kidsw with ADHD to focus. But without studies that specifically look at fidget spinners, it's impossible to say for sure whether the devices could help kids with ADHD.

However, no matter the reports say, there is stil something we and parents can do on their part keeping  kids safe while fidget-spinning.

  1. Shop at reputable stories
  2. Follow tips for light-up spinners (make sure the spinner's battery is locked in the toy)
  3. Check for broken parts (which can be a choking hazard).
