How Do Birds Fly?
If you tried the paper activity from the front of this article, you might have been surprised by what happened. In most cases a person would think the paper would go down and not lift up when they blow air across the top.It may not be what you would expect, but it is what birds and planes do to lift off the ground and fly. Blowing faster-moving air above the sheet paper lowered the air pressure above the paper. Now the air pressure below the paper is higher and creates lift. Lift does exactly what it sounds like; it lifts objects off the ground when everything is just right.We blew air over the top of the sheet of paper to create the lower pressure. You cannot do that for birds and planes. Instead, the wing of both birds and planes are shaped so that air passing over the top has to travel a longer distance and so it has to speed up as it goes over the top of the wing. This creates the difference in pressure above and below the wing.
