Water balloons, silly preschoolers
Blow up four water balloons with air. Ask your kids to rub the balloon quickly on their hair. Now, most of us know that static electricity will lift your hair if you hold the balloon a small distance away from your head, but a water balloon will "stick" to your hair, your hands, your arm, your tummy and even the walls! You must rub the balloon where you want it to stick to create the static charge.
