Plastic
From Simple English Wikipedia, the free encyclopedia
A plastic is a material that can change its shape, so many things can be made of plastic. There are many types of plastic. Some can be shaped only when they are freshly made; then they become hard afterwards. Others can be changed by heating them up or even by melting them.
Most plastics are man-made; they do not occur in nature. They are often made from oil that comes out of the ground. The process of making plastics is usually quite complicated.
