SuperBall (originally "Super Ball") is an example of a bouncy ball invented by Norman Stingley, and manufactured by Wham-O in 1965. It is an extremely elastic ball made of Zectron, which contains the synthetic rubber polymer polybutadiene, vulcanized with sulfur at a temperature of 165 degrees Celsius and at a pressure of 80 atmospheres. The Super Ball has an amazingly high coefficient of restitution. Dropped from shoulder level, Super Ball snapped nearly all the way back; thrown down, it could leap over a three-story building.
After watching his kids play with a Super Ball, Lamar Hunt, founder of the American Football League, coined the term Super Bowl.
