Making a small pulley showcases how a pulley system works and what it can be used for. Constructing a pulley is a way to model a Science lesson or create an after-school project to complete with children. Making a pulley requires simple household items and no more than thirty minutes of your time.

Things you need

  • 8-10 inch length of wire - about the gauge of paper clip wire or smaller

  • Wooden thread spool

  • Needle nose pliers

  • Cabinet handle or wall hook

  • 12- to 15-inch length of string

  • Paper clip

  • Pencil or other small object

Place the wire through the wooden spool. Use a gauge of wire that allows the spool to spin.

Bend the wire into a triangular shape and twist the ends together using needle nose pliers.

Attach the spool to a secure location by hanging the wire on a fixed object such as a cabinet handle or wall hook.

Place the string over the spool. Tie a paper clip to one end of the string and tie the other end around a small object such as a pencil.

Pull the paper clip. The spool should slowly turn, raising the pencil or small object.
