Ball and Air Pipe $2.95

Blow into the 6 inch wood pipe and watch the ball begin to float in the blowing air. Why?? Shouldn't it be pushed by the air and fall off to the side? It doesn't fall even if you start to tip the pipe! Now is that really strange - or is it science?

The answer is found in the Bernoulli effect. Moving air has lower pressure than stationary air, so the ball is actually being pushed into the moving air by the non-moving air.

Here is a basic definition of the Bernoulli equation. For a more detailed explanation of the Bernoulli effect, click here.

Includes 2 styrofoam balls.

Not intended for children under three years of age.
