Wham-o founders Melin and Knerr, heard of Australian children using a bamboo ring for exercise and immediately turned out...you guessed it...HULA HOOP® toy hoop. They promoted it for months in 1958 on Southern California playgrounds where they would do demonstrations and give away hoops to get the children to learn and play. The hoop is back new and improved, we have a great selection of hooping products.
