Rubber is the material that's used to make things like bouncy balls, rain boots, and car tires. Most rubber comes partly from rubber trees.
To make rubber, manufacturers harvest latex from rubber trees by tapping them — the process is similar to collecting sap from maple trees. It's then refined and processed, often with other materials, to make things ranging from conveyer belts in factories to balloons and the gloves doctors wear. When rubber first arrived in Europe in the 1700s, it was made into erasers, and the idea of rubbing out mistakes led to the word rubber being coined.
