This is a really cool trick I saw on t.v. this morning on the Ellen DeGeneres show. Take a hair dryer and a ping pong ball and you put the ping pong ball in the air right in front of the hair dryer when it is on. It will float in midair. It does this because the pressure from the hair dryer blowing pushes it up in the air and then it goes over the ball to keep it from flying up in the air. My sister and I we able to get two of them floating at once and they knocked into each other and clicked. A hint: if you hold the hair dryer straight it will keep the ball up there. This was so fun, we tried it many times today.
In this picture it looks like the ball is my nose!
