Fidget Spinners Explained

How do Fidget spinners actually work?

let's take a look!


This can be explained by physics and looking into how bearings work to reduce friction. Ball bearings in this case are constructed of an inner and an outer ring.

In between this inner and outer ring sits balls that look to limit the amount of friction between the two rings. A bearing like the one pictured here can be found in the centre of the fidget spinner. Once you combine the physics theory of continued angular momentum with a bearing the limits friction you should get a free spinning fidget spinner. The outer arms of the fidget spinner have weights in order to increase the rotational force or inertia once moving. Now generally it is thought that there is centrifugal force being applied to these weights, but it is not, it is actually a centripetal force!  this forces is is being created by the arms preventing the linear motion of the weights within them.

So what purpose does the fidget spinner have, well it is great for those who suffer from Autism, with some sufferers finding these toys very soothing, also those who find it hard to concentrate can also benefit from fidget spinners.

Sow how can we improve our fidget spinners? This is simple! upgrading the fidget spinners central bearing to a high quality bearing will defiantly improve its spinning speed and the time it spins for.
