Bernoulli Blower

♥ Sponsored by Santa Rosa Soroptimists

A ball floats, bobbing up and down, above a tube in this exhibit. When you get up close, you find out that the ball is floating on a stream of air (generated by a large fan). If you slowly try to pull the ball out of the airstream, you can feel it being pulled back in. Tilt the tube in different directions, and the ball will be suspended in space off to the side of the blower as if held there by magic. Named after the Swiss scientist, Daniel Bernoulli, this fun and creative exhibit teaches children about the Bernoulli principle and how airplanes stay aloft.
