Bernoulli Blaster Experiment

This experiment awesome way to demonstrate the unexpected effects of low air pressure with an leaf blower. A fast stream of air across the top of this clear tube lowers the air pressure in the tube. As a result, high air pressure below the tube propels the ping-pong balls upward in the tube, in apparent defiance of gravity! The balls are pushed up the tube right into the stream of the leaf blower and off they go.
