英语百科

Super Ball

A Super Ball containing particles of glitter, resting on a base. The rubber has yellowed with age.
A branded Wham-O Super Ball from 2001

A Super Ball (a.k.a. SuperBall) is a toy based on a type of synthetic rubber invented in 1964 by chemist Norman Stingley. It is an extremely elastic ball made of Zectron which contains the synthetic polymer polybutadiene as well as hydrated silica, zinc oxide, stearic acid, and other ingredients. This compound is vulcanized with sulfur at a temperature of 165 degrees Celsius and formed at a pressure of 3,500psi. The resulting Super Ball has a very high coefficient of restitution, and dropped from shoulder level, a Super Ball snaps nearly all the way back; thrown down by an average adult, it can leap over a three-story building.
