Water wiggly sprinkler death

Greatness comes in many guises. Some people are born to rule, some make amazing discoveries, some demonstrate extraordinary bravery. For Richard Knerr, who has just died at the age of 82, the path to immortality involved jumping through hoops - thousands of them. To the man who gave us the Hula Hoop, the Frisbee, the SuperBall, the Water Wiggly sprinkler, the Slip N'Slide water slide and Silly String, not to mention the do-it-yourself bomb shelter, I would like to say thank you.
