![]() "If you put the ball bearing at the centre of a disk, you must start the spin by pushing on the outer part," Doherty said, referring to the fact that the object's centre of mass would be at the centre. ![]() At the centre, 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, Doherty said.Īnd when it comes to spinning, shape matters. This same principle can be applied to the spinners. That's because friction associated with rolling motion is typically less than so-called sliding friction. "I bet the marble goes farther," Doherty said. ![]() To understand why to try this: Slide a block of wood or other material across the floor. The reason why fidget spinner spin for long is physics.īall bearings are key to this spinning toy. This is the easiest way of making the Fidget spinner at home and the material is quite basic that can be found at an electrical shop and at a sports shop. A basic fidget spinner consists of a bearing in the centre of a design made from any of a variety of materials including brass, stainless steel, titanium, copper, and plastic.
