Natural rubber was discovered in the western part of the world in the late 15th and early century in the west indies and central America. We have recently discovered that it had been used by natives from that region from at least 1600 B.C.One of the oldest tribes from the region are the OLMECS witch translates into the rubber people. Rubber Balls were important to the cultural religion of the Mayans it apparently was used in a games that was more like a fight to the death than a sport. The game is known as Mesoamerican ball game witch is still a game played to day. That is how the creation of rubber and balls have an effect in history.
I believe that the ball bounce effect has revolutionized history because with out it we would never have had such glorious devices like the bounce house been created. Many things have been done since the discovery of the bounce effect in 1925. Bungee cords, bounce houses, and all other types of creations that involve the bouncing. A lot of many discoveries have been made since the discovery of bouncing.
Without the discovery of the Mesoamerican rubber a lot of things would have never been invented or maybe not discovered as soon as it was such as rubber stopper or the rubber bottom to shoes even the rubber on the wheels of a car.
In america we have a lot of rubber stuff like erasers pencil and pen grips.
Rubber is pretty important.
