Floating  Ping  Pong Ball Experiment

- Ping pong ball - Blow dryer

Materials Needed:

Place a ping pong ball on top of a blow dryer facing up and turned on.

Step 1

Notice how the ball appears to float on top of the hot air even as you move the dryer around.

This is because the dryer produces a column of quick-moving air with lower air pressure and the surrounding air with higher air pressure holds the ball in place.
