STATIC ELECTRICITY

Stuff you need

1. A balloon
2. A piece of wool

How to do

1. Blow up the balloon
2. Rub the balloon with the wool cloth (in the winter you can usually just rub it on your hair)
3. Stick the balloon on a wall or ceiling if you are tall enough

Result

1. The Balloon will hang where you placed it for a while. The dryer the air is, the longer it will hang.

Why

1. When you rub the balloon, you remove some of the electrons from it. This gives the balloon a positive charge.
2. The molecules that are missing their electrons form a bond with molecules on the wall.

Extra stuff to do

1. Try different sizes and shapes of balloons
2. Rub balloon on different items
