This
experiment consists of a funnel and hose connected to high air pressure
in order to trap a ping pong ball inside the air stream. The ball is placed
inside the funnel as the air rushes out of the funnel and pressure differences
created by the Bernoulli and Coanda Effects keep the ball from being blown out of the
funnel. See these links for more information:
