Bernoulli and Coanda Effect Funnel

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.
