A Bernoulli Levitator

Can you balance a ball in a vertical stream of water without using the Bernoulli Principle? The video shows how to achieve this with multiple balls and even discs. It describes how the ball remains stable even when off to one side of the...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a little boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll of...

Two versions of this activity are presented for you to choose from when teaching about Bernoulli's principle in your physical science class. One is a hands-on activity, while the other would be best used as a demonstration during...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...
