Beakman challenge: Hold a ball inside an upside down funnel without touching the ball. Beakman puts the ball inside the funnel as he is running water hose water through it. He uses an animated clip to explain how it's working and that it's Bernouilli's principle.
Beakman's Challenge: Put a ping pong ball in a funnel and try to blow it out of the funnel. When Lester tries to blow from the bottom, it won't work due to Bernouilli's principle. Liza shows him that he has to blow the ball out of the funnel from the top.
Beakman acts as Bernouilli to explain his principle, how it involves air pressure, and how it affects planes. He uses a demo of blowing on a strip of paper to show that it lifts the paper due to changes in air pressure. Then he blows between two balloons, and they press together due to the decrease in air pressure between them. Beakman conducts a demonstration to show how to draw liquid out of a straw by changing the air pressure.
