A spring is made of some material wound around a cylinder shape. If a spring is going to be useful it needs to be made of stiff material that will keep its shape. Springs are useful because once they are made into a shape, they want to stay in that shape. They are usually made of metal, but they can sometimes be made of very strong plastic as well. Find out all about this simple machine in this title.
