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.
