Ping Pong Ball or any very light ball
1. Turn on your hair dryer and point it upwards. So the air is blowing at the ceiling.
2. Put the ping pong ball into the air stream.
3. If you’re careful the ping-pong ball should stay in the air stream suspended in midair!
4. You can even tilt the hair dryer a bit and the ball will stay in the stream.
5. You can sometimes get two and even three balls or balloons into the stream at the same time!
