Summary:Here's a quick, simple, and inexpensive demonstration of an induced static charge. Everyone has probably demonstrated static induction by first rubbing a balloon across his or her hair or animal fur and then sticking it on a wall, whiteboard, or chalkboard. Now you can add a humorous twist to that golden oldie. You will need two balloons (the type clowns use to make animal shapes), an animal fur friction pad or your hair, and a marking pen. Inflate both balloons to their full length and tie off the openings. Along the center of one balloon, in large letters write the word “Rover.” Allow the ink to dry and you are ready for the demonstration.
