Many of us have played with a hula hoop, and most of us have probably failed. In fact, hula hoops are one of those weird inventions that have been around for centuries. The Greeks used to use hula hoops as a form of exercise. Through the centuries, the hula hoop has gone through many modifications and improvements. The original hula hoops were made of bamboo, wood, and vines. Founders Richard Knerr and Arthur “Spud” Melin, from the Wham-O company, decided to take the hula hoop and trademark it. It was then that they manufactured the toy from plastic tubing and became one of the weird inventions we see today (Wonderopolis).
