Likes Repel

Inflate two balloons and hang them from a common point on the ceiling by string. Rub both balloons against your head hair to charge them in like manner. The balloons are charged with like charge as one another. Move away from the balloons and observe the noticeably large repulsions between the two like-charged balloons. This demonstrates the repulsions of two like-charged objects.
