Bouncy ball

"Rubber ball" redirects here. For the Bobby Vee song, see Rubber Ball.

Various bouncy balls.

A bouncy ball, power ball or super ball is a popular polybutadiene rubber toy ball which rebounds proportionally to the amount of force used when thrown at a hard surface. The first such ball was the proprietary Super Ball. The Sky Ball is an example of another bouncy ball. The Sky Ball has lately been praised for its successful claim to bounce higher than the Super Ball.

In some countries, for example the United States and Denmark, they are often sold from bulk vending machines for 25 cents or more.
