All you need is very rudimentary fluid dynamics, some vague idea of attack angle, and the conservation of momentum with a compressed column of air under the plane. I think most theoretical physicists could come up with that. The siphon one is funny because many people will start with air pressure, which is wrong. I'm wondering if you have some experience asking people these questions?
