Across the Internet, people are discovering a new and deviously simple device that helps those with attention disorders (or really anybody that likes to keep their hands busy when doing work or trying to focus).

Known as "Hand Spinners" or "Fidget Spinners", they’re becoming incredibly popular and even have their own trending subreddit dedicated to them.

They’re available in a stunning array of designs, colors, and materials but their core principle is all the same
