Mr. Ramirez demonstrates that objects can exert forces on each other even when the objects are not touching. He removes two long pieces of clear plastic tape from a tape dispenser. He holds a piece of tape in each hand so that they are hanging down. As he moves his hands closer together, the pieces of tape repel each other. His students then plan an investigation to study the forces exerted by the pieces of tape.
