The Force

The Force

Today at school. I did an experiment that makes a Ping pong ball float in the air. Why. In here it will tell you how to do the experiment and how it works.

What you will need: 

A Hairdryer

3 ping pong balls. 

How to do the experiment

1. Hold your hairdryer in midair turned on. It will need to be on a high setting. 
2. Put a ping pong ball on top of the hairdryer and it will float. 
3. If you will like to you can add on another ball and another

How and Why does it work. 

This works because the air that the dryer is making is pushing it up. Why cant it go high. The invisible force called Gravity is battling against the wind to pull it down. If you add another ball. They will bobble up and down and one of them will fall off. This is because the wind field if not wide enough to hold both balls inside its field.
