Why was the fidget spinner made?

The fidget spinner was originally invented in the 1990s by Catherine Hettinger as a stress-relief toy for children and adults with attention disorders or anxiety. It gained massive popularity in 2017 as a tool for helping individuals focus and manage anxiety through repetitive motion. Its design allows users to spin it between their fingers, providing a tactile experience that can be soothing. The toy became a cultural phenomenon, often marketed as a way to improve concentration and reduce boredom.
