What happens to the balloon and your hair when you rub a balloon on your head? What would happen if I took the balloon and stuck it to the wall?
The balloon takes the electrons from your hair, leaving your hair with positive charge so it sticks up. If you stuck it to the wall, it would stick because the negative charges in the balloon attract to the positive charges in the wall.
