The fidgety spinner is a toy consisting of bearings in the center of a multi flap flat structure made of metal or plastic designed to rotate easily along its axis.

Although similar devices were invented as early as 1993, the gadget spinner became a popular toy in 2017. This kind of toy is very popular among schoolchildren, so some schools prohibit the distractor, while others allow the toy to be used cautiously.

The toy is advertised to help people with attention or restlessness by relieving nerve energy or psychological stress. As of May 2017, there is no scientific evidence that they can effectively treat autism or ADHD.

The gadget spinner is a useless machine designed to rotate easily. The basic annoying spinner consists of a two pronged or three pronged design with a bearing in the center of the circular pad. As the toy spins, one person holds the center mat. They are made of various materials, including brass, stainless steel, titanium, copper, aluminum and plastic. Bearings are usually ceramic, metal (stainless steel or chromium alloy), and some are hybrid bearings, such as ceramic balls with stainless steel raceways and cages. Each fidgety person also has two or more weights on the outside to spin faster and maintain balance. Bearings can be varied to accommodate the design's rotational time, vibration and noise, resulting in unique sensory feedback.
