Funnel Challenge

Try this fun challenge to learn more about air pressure!

You Will Need:
- A clean funnel
- A ping pong ball

Try This:

• Place the ping pong ball into the funnel
• Hold the funnel upright and blow through the bottom to try to blow the ball out of the funnel.

What's the Science?
This is another example of Bernoulli's principle at work (see explanation). When you blow through the funnel, the air below and around the ball is moving very fast and so has very low pressure. In comparison, the still air on top of the ball has more pressure, and pushes the ball down into the funnel. The harder you blow, the harder the ball is pushed back into the funnel!

When you're at the California Science Center, be sure to visit the Air Pressure Cart in the Disney Court.
