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!
