How Do Aero planes Fly?

We’ve all heard that air is the reason that aero planes fly. Let’s know how?.

Here’s what happens:
The airplane’s wing is teardrop-shaped. Air that flows over the top of the wing has to travel a longer distance than the air that flows below the wing, so the air above has to move faster.
This pulls air molecules away from each other, which means they put less air pressure on the top of the wing than the bottom.

        But planes are very heavy, right?

       So here’s a secret, try this out!

  • Sometimes it’s hard to believe that quick-moving air can lift a big plane in the sky.  But this can be easily seen using just a piece of paper and your mouth. By blowing over the top of a strip of paper you can see how.
  • The special shapes of planes help them to fly.

What’s happening?

When you blow fast-moving air over the top of the strip of paper, the air pressure decreases above the paper. The air pressure below the strip is a little bit higher and it pushes the paper upward.

To do this, blow over the top of a strip of paper held loosely from one end. Hold the paper strip with both hands and then blow lightly but steadily. Blowing quickly or strongly will make the paper flap.
