Floating Ball

Need: small balloon or ping pong ball, hair dryer

Get a hair dryer and hold it so the nozzle is facing straight up towards the ceiling.

Turn the hair dryer on.

Take the ball or balloon and place it about 5 inches from the hair dryer in the stream of hot air.

Let go and you should see the ball floating in the air!

Grab the ball with your hand and move it to the side, make sure part of it is still in the stream of hot air.

You should feel the ball trying to get back to the center of the air flow.

Move around the room if you can all the while balancing the ball.

See what parts of the room make the ball go higher in the air (hint - try a corner!).

Then move to the middle of the room. Notice a difference?

Try both a balloon and a ball. Which one seems to stay up in the air longer?

Is one harder than the other to keep afloat? How long does the balloon stay in the air. What about the ball?

Now try BOTH a balloon and a ball. Is the air stream wide enough to keep both afloat?

Does one seem to be floating in the air easier than the other? Is one able to go higher in the air than the other?
