A fidget spinner is a toy that consists of a ball bearing in the center of a multi-lobed (typically three) flat structure made from metal or plastic designed to spin along its axis with pressure. Fidget spinners became trending toys in 2017, although similar devices had been invented as early as 1993.[1]

The toy has been promoted as helping people who have trouble focusing or those who may need to fidget to relieve nervous energy, anxiety, or psychological stress. There are claims that a fidget spinner can help calm down people who have anxiety or neurodivergences, such as ADHD and autism,[2] though peer reviewed studies for this notion are lacking.[3][4][5]
A spinner consists of a round, flat central bearing (usually a ball bearing) that allows the arms connected to it to rotate; around this central axis, there are usually three weighted arms, but their number varies depending on the model. They can be rotated for up to several minutes, depending on the model
