Something in the Air

Here's a fun experiment we did this week you could try at home. All you need is

 • Hair dryer • A Ping pong ball • A polystyrene ball

What to do:
 1. Set the hair dryer to cool, switch it on, and point it at the ceiling.
2. Carefully put the ping-pong ball in the stream of air. Hold the hair dryer very steady and watch as the ping-pong ball floats in the stream of air.
3. Carefully move the hair dryer from left to right and watch how the ball moves as well, staying in the stream of air.
4. Try floating the balloon over your ping-pong ball.
5. Try to float the polystyrene ball in the same air stream as the ping pong ball. How do they behave when there is more than one?
