A fidget spinner is a small, handheld toy designed to spin around a central bearing. Typically made of plastic or metal, it has three prongs that allow it to be easily held and spun. Fidget spinners became popular in the mid-2010s as a tool for stress relief and focus, especially among children and teenagers. These toys are often used by individuals who experience anxiety or have attention disorders, as they can provide a sensory outlet. While some studies suggest they may help with concentration, others argue that they can be distracting in certain environments, such as classrooms.
