The easiest way is to take a reel of thread and put it on a rod.
Alternate would be to take a rolling pin ( used to make chapatis) and hold it loosely in your hand.

A pulley is a type of simple machine. It is used to lift a load. This makes it easier for the person lifting the load because it takes some of the weight off them and puts it on the pulley. Making a pulley science project will let the maker study areas in science such as force, work, energy, effort and gravity
