This is step 2, create static electricity, of the Home Science badge for Brownies.
Balloon Food Coloring Spoon 1 empty paper/plastic cup 1 cup of water thumb tack 1 large bowl
We will be bending water with the power of static electricity!
What Happens: The water bends toward the balloon.
How it works: Your hair has a neutral electrical charge. When you rub the balloon against your head, the balloon takes some of the electrons from your hair, which leaves your hair positively charged and the balloon negatively charged. Your positively charged hair is now attracted to the negatively charged balloon, which is why your hair moves towards it.
Water, also known as H2O, is made up of two hydrogen atoms and one oxygen. The hydrogen atoms have a slightly positive charge. Similar to your positive hair, the hydrogen atoms are attracted and move towards the negative balloon!
