60 Second Science: Electric Hair

magnets-930w

Science is fun! Use static electricity to teach your child about positive and negative charges

What you will need:

inflated balloon

wool sock

Rub the wool sock on the inflated balloon or you can rub the balloon on your hair. You will start to hear crackly sounds. Have your child place the balloon on his head.

What happens? The balloon sticks to his hair! Rubbing the balloon with the wool caused negative electrical charges (static) to collect on its surface.   Hair is positively charged, and like a magnet, the balloon is attracted to the hair and sticks.
