Discover how flowing air follows curved surfaces because of the Coanda effect and principles of fluid mechanics. See the forces that cause ping pong balls to float in a jet stream, and find out how saucer-shaped objects can fly.
Fluid dynamics. Air is like a fluid in its motion. It has to go and be somewhere. The only thing I would like to know about is how semi circle flies. With a smaller propeller on the top but If im right thing then i could see how it would create a suction effect. Instead of a lift.
