Experiment: Rub the water pipe with the cloth, then bring the pipe near the can.
Observation: Rub the surface of the water pipe with the cloth for 40 seconds. Then place the can on a flat and smooth surface. Next, hold the water pipe close to the can without touching it and watch as it follows the movement of the pipe.
Explanation: Rubbing the water pipe with the cloth creates static electricity. The pipe, which has gained electrons, becomes negatively charges. Hence the can, which is positively charged, is attracted to it as opposites attract.
