Although South Americans have created rubber from the sap of hevea trees for generations, the growth of the automobile industry in the early 20th century greatly increased the international demand for the product by the 1930s. This video shows the traditional method of generating rubber. First the worker carves diagonal grooves into the bark of the hevea tree. Then she harvests the sap that runs down the grooves. Finally she hardens the rubber over a fire, pouring the sap over the growing ball of solid rubber.
