I found a really cool article on fidget spinners I wanted to share, I have added some of the story but i would recommend checking out the original from Live Science

Fidget spinners ― kids spin them and spin them ― and while parents may not “get” why the boomerang-shaped toys have caught on with such force, there’s real physics to explain how the distracting devices work.

“I was introduced to fidget spinners a few months ago by professor Kenneth Brecher from BU [Boston University],” said Paul Doherty, a physicist at the Exploratorium in San Francisco. “He makes his own spinning toys and handed me a fidget spinner and asked me to guess what it was. I described what it did but had no idea why someone would buy one ;-),” Doherty told Live Science in an email.


For Doherty, the spinners are interesting for another reason: “To me, these show the coolness of ball bearings that reduce friction and allow things to rotate freely for a long time.” (On a basic level, friction is the resistance to motion that occurs when one object moves relative to another.)
