A fidget spinner or hand spinner is a fidget toy composed of a central ball bearing and two or more weighted lobes that rotate around the central axis when spun. Typically made of plastic or metal, the toy operates on basic mechanical principles such as angular momentum and low-friction motion, allowing it to spin smoothly and for extended periods. The toy rose to widespread popularity in 2017, and was marketed as a variety of uses, including stress relief and support for individuals with attention-related conditions. Although some proponents claimed therapeutic benefits for conditions such as attention deficit hyperactivity disorder (ADHD) and autism, empirical studies have not substantiated these claims. Reception was mixed, with reports of both positive user experiences and criticism regarding classroom disruptions and safety concerns.
