What’s it about?

It is often hard to imagine just how an airplane stays in the air, not to mention fly over great distances! Planes stay in the air by using the wind indirectly through ‘Bernoulli’s principle’. Daniel Bernoulli, a Swiss scientist, made the following statement: ‘When any fluid, such as air, flows, its pressure decreases as its speed increases’. In this science experiment we will see how this decrease in air pressure can lift planes off the ground and fly:

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

In this science experiment, the paper plane flies because when the plane’s wings moves through the air, some of the air goes above the wing, and some of the air passes below the wings. The wings of this plane and all other planes are designed so that the top surface of the wing is slightly larger than the bottom surface of the wing. By designing it this way, it forces the air moving over the top surface of the wing to flow slightly faster than the bottom surface. This creates a decrease in air pressure above the wings, allowing ‘lift’ to take place and makes the airplane fly!
