context_page_description: A Super Ball 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 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 °C and formed at a pressure of 3,500 psi. The resulting Super Ball has a very high coefficient of restitution, and if dropped from shoulder level on a hard surface, a Super Ball bounces nearly all the way back; thrown down by an average adult, it can fly over a three-story building.
  Toys similar to Super Balls are more generally known as bouncy balls, a term that covers other balls by different manufacturers with different formulations.
