A spinner, often referred to as a fidget spinner, is a small, handheld toy designed to be spun between the fingers. Typically made of plastic or metal, it features a central bearing that allows it to rotate smoothly. Fidget spinners gained popularity in the mid-2010s as a tool for stress relief and focus enhancement, particularly among children and adults with attention-related challenges. These toys come in various shapes, sizes, and colors, appealing to a wide audience. While some users find them helpful for managing anxiety or improving concentration, others view them as mere novelties. Despite the debate over their effectiveness, fidget spinners remain a common sight in schools and workplaces.
