A Super Ball or Superball is a toy bouncy ball based on a type of synthetic rubber invented in 1964 by chemist Norman Stingley. 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 ]
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.
The two decided to market the bouncing putty by selling it in a clear case. Although it sold well, Fallgatter did not pursue it further. However, Hodgson saw its potential. [1] [5] Already US$12,000 in debt, Hodgson borrowed $147 to buy a batch of the putty to pack 1 oz (28 g) portions into plastic eggs for $1, calling it Silly Putty.

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 ...
