But no worries, reason prevails: Fidget spinners banned from schools for making too much noise. For the uninitiated, a fidget spinner is a “palm-sized spinner containing ball bearings which can be flicked and spun around.” And why do they exist (other than to torment us)? Actually, they were designed to help students with ADHD and autism and it’s thought that they help with concentration, but they became “a fad after YouTube bloggers gathered millions of views by performing tricks with them.” So students who were playing with fidget spinners for fun and not to help them concentrate were interfering with students trying to concentrate. While the linked story was about a ban at a UK school, you’ll be glad to know that fidget spinners are also banned in 32% of the largest high schools in the U.S. So far.
