Humans have developed quite a few inventions throughout the millennia. The wheel was a good one. Electricity is hard to beat. But the light bulb, that was absolutely brilliant! The internet, the iPod, and cell phones are more recent feats of innovation by the mighty human. But how about the hula-hoop? It’s one of the biggest trends ever to hit American teens.
