Get Your Science On: Soaring Sphere

In this episode, and show us how to make a beach ball levitate in the air! All you need is an air blower and a ball.

What’s Going On

The center of the air stream is moving fast. Bernoulli’s principle tells us that faster moving air has lower pressure, so the ball is stable in a region of relatively low pressure. There are some neat tricks you can do, like increasing the pressure behind the ball with your hand which moves the ball without even touching it!
