The SuperBall, also known as the bouncy ball, was invented in 1965 by Norman Stingley. At the time, Stingley was a chemist living in California. He would take scraps of rubber and pack them together with up to 3500 lbs of pressure per square inch. This made the ball super bouncy. When dropped from shoulder height, it would bounce right back. And if an adult throws it down, it can bounce as high as a three-story house. The SuperBall went through many changes before it was released to the public. At first, the ball would fall apart if it hit a surface with too much force. The toy company Wham-O made it better, and two years later, it hit the shelves. It was an immediate success. To this day, SuperBalls are popular all over the world. 7 Which is the best summary of the article? A. The SuperBall was invented by Norman Stingley in 1965.
