Consists simply of the reversed vacuum cleaner and a lightweight plastic ball.

Demonstrates the Bernoulli Theorem by using a flow of air to levitate a ball.

• Reversed vacuum cleaner
• Plastic Ball

1. Turn the vacuum on and drop the ball above the nozzle.
2. The ball will then remain suspended in air due to the Bernoulli effect.

A plastic cup attached to the side of the vacuum is used to hold a ball specifically for this demo. If it's missing, we should have more.
