Do you know how to describe why things fly?

• 1. Air has pressure. 2. To get things to fly you need differences in air pressure. 3. When you get an angle of attack there is low pressure on top and high pressure on the bottom to create lift.

• 1. Air has no pressure. 2. To get things to fly you need no air pressure. 3. When you get an angle of attack there is low pressure on top and high pressure on the bottom to create lift.
