A superball or power ball is a bouncy ball composed of a type of synthetic rubber (originally a hard elastomer polybutadiene alloy named Zectron) invented in 1964, which has a higher coefficient of restitution (0.92) than older balls such as the Spaldeen so that when dropped from a moderate height onto a level hard surface, it will bounce nearly all the way back up.

It is an extremely elastic ball made of Zectron, [ 1 ] which contains the synthetic polymer polybutadiene as well as hydrated silica , zinc oxide , stearic acid , and other ingredients. [ 2 ]
The bounce of an oval-shaped ball (such as those used in gridiron football or rugby football) is in general much less predictable than the bounce of a spherical ball. Depending on the ball's alignment at impact, the normal force can act ahead or behind the centre of mass of the ball, and friction from the ground will depend on the alignment of ...

The space hopper is a heavy rubber ball about 60–70 centimetres (24–28 in) in diameter, with two rubber handles protruding from the top. A valve at the top allows the ball to be inflated by a bicycle pump or car tire pump. A child can sit on top, holding the two handles, and bounce up and down until the ball leaves the ground.

To cork a bat, a hole 1 ⁄ 2 inch (13 mm) in diameter is drilled down through the thick end of the bat roughly 6 inches (150 mm) deep. Crushed cork, bouncy balls, sawdust, or other similar material is compacted into the hole and the end is typically patched up with glue and sawdust.
