History...
In the early 1960s, Norman Stigley, a chemical engineer, combined polybutadiene and sulfur into a compound called Zectron. He offered the product to Melin and Knerr and the SUPERBALL® was created, followed by the Super Gold Ball, Super Baseball and Super Dice.
In one celebrated incident, a giant SUPERBALL, produced as a
promotional item, was accidentally dropped out of a 23rd floor
hotel window in Australia. It shot back up 15 floors, then down
again into a parked convertible car. The car was totaled but the
ball survived the "test" in perfect condition.
During the 1960s, WHAM-O sold some 20 million SUPERBALLs before
it was copied by competitors and WHAM-O bounced the ball from its
product line. If you're one of the countless others who've never
been satisfied with mere copies, the wait is over! WHAM-O has
broughtback the original SUPERBALL!
