Fidget spinners are small, handheld devices designed to spin around a central bearing. They typically consist of a plastic or metal body with three prongs, each containing a bearing. Users can hold the center and flick the prongs to make the spinner rotate. Originally marketed as a tool for reducing stress and improving focus, they gained immense popularity among children and adults alike. These toys became a cultural phenomenon in the mid-2010s, often seen in schools and offices. While some people find them helpful for concentration, others argue that they can be distracting. Fidget spinners are part of a broader category of fidget toys aimed at providing sensory stimulation.
