Ever wondered how an airplane is able to fly?Here's how! Hold a piece of paper by one end, and let the other end hang down. | |
Hold the paper near your mouth, but a little bit below your mouth.Take a deep breath and blow hard over the top of the paper. See how the paper rises into the air? When a strong wind blows over the paper, it creates a vacuum above the paper which sucks the paper into the air. In the same way, a strong wind blowing over an airplane wing creates a vacuum over the wing which sucks the airplane up into the air! |
