The Amazing pulley
By Justin O.
What is a Pulley?
A pulley is made out of rope with a type of leather that is stretchy and it is used to carry big heavy things like metal poles. They can be attached to big cranes and the cranes have big chain pulleys. Sometimes pulleys have wheel and axels on them like a wishing well. Without the pulley you would have to dive into the wishing well to get the bucket. But with the pulley you can just pull up the bucket and fill it with water. Pulleys can be used to lift up flags too. Imagine life without the pulley.

The U.S.A flag
Imagine trying to lift a flag without the pulley? You would have to climb up the pole. Try doing that! Go break a leg.
