18 What is Rubber?

Rubber is extracted from trees in nature. This rubber is further treated by heating it with "sulphur" to make it hard and durable. This process is called "vulcanization". Vulcanization is invented by a scientist named "Goodyear". This rubber is then used to make tires which are essential for transportation.
