Super Ball
A Super Ball (aka 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.

List of The Price Is Right pricing games
Pricing games are featured on the current version of the American game show The Price Is Right. The contestant from Contestants' Row who bids closest to the price of a prize without going over wins the prize and has the chance to win additional prizes or cash in an onstage game. After the pricing game ends, a new contestant is selected for Contestants' Row and the process is repeated. Six pricing games are played on each hour-long episode. Prior to expanding to one hour in length, three games per episode were played during the half-hour format. With the exception of a single game from early in the show's history, only one contestant at a time is involved in a pricing game.
