NOTE: it is always good to wear safety glasses when doing any science experiment.
PING PONG BALL BALANCING ACT: SUPPLIES: A hair dryer and a ping pong ball and cotton ball. Turn the hair dryer on and hold it so it blows straight up. Gently place the ping pong ball on end and see how long it will float in the air. See how far you can tilt the dryer before it falls off. Now try the cotton ball. What happens? How does the smooth shape of the ball help it stay in place? This experiment explores aerodynamics.
