You've no doubt seen a kid or two playing with the hottest new toy craze, the fidget spinner. It's basically a little triangular piece of plastic with a couple of bearings in it that you hold in your hand and spin on your finger. It's made for people who can't stop fidgeting. Pretty smart of someone to cash in on this, right? Well, the woman who invented the fidget spinner is not cashing in at all. In fact, she hasn't made a dime off of her invention!
