The Science of Static Electricity

Rubbing a balloon on your head creates an invisible force. Seriously. When you do it,

the balloon becomes negatively charged, and your hair becomes positively charged. It's a basic rule

of physics: opposites attract. That's why your hair literally reaches out and sticks to

the balloon. But here's the twist. If you charge a second balloon on your hair,

the two balloons will push each other away. That's because things with the same charge

repel. So that crazy hat hair you get in the winter? It's just your individual

hairs, all positively charged, trying to escape from each other.
