Bernoulli Levitator

Bernoulli LevitatorBernoulli Levitator graphically demonstrates the Bernoulli principle. A large wooden disk suspends itself in space when placed close to a strong downward stream of air. Basically, the air forced down on the disk moves faster than the surrounding air, lowering the air pressure on top of the disk and keeping it aloft. By pulling on the disk itself, visitors can feel the force of the pressure holding up the disk.
