History of Rubber
Untill recently many people thought rubber was invented in 19th centuary Europe, but on July 14, 1999 Professor Dorthy Hoseler, Assistant Proffessor Sandra Burkett and an under graduate named Michael Takanian learned that the Myan people invented rubber as long as 1600 BCE.

To make rubber Mayan people used Latex. Latex is the sap of various plants, usually the rubber tree. Whenn exposed to the air the rubber hardens into springy mass. Mayans mixed the rubber sap with the juice from morning glory vines so that it became more durable, elastic, and did'nt get quite as brittle.

Later in 1776 several roles of rubber were sent to France. Next in 1791, an Englishman named Samuel Peal discovered a waterproofing cloth by mixing rubber with turpentine. Joseph Priestly got some rubber and discovered it could be used to erase pencil markings. Charles Goodyear an American also userd rubber to make the tire.

Today about three quarts of the rubber is mad
