In this demo, a polyethylene strip is charged by rubbing with wool. The strip is then used to test what happens to the flow of charge when the strip is placed in contact with a conductor (iron nail) and the materials are then moved towards a neutral object. An extension to the demo enables students to test what happens when an insulator (eraser) is used in place of the conductor (iron nail).
