does a propeller screw itself on air or is it just reaction

[winny]

Only Raaaaaaaid would ask if an airscrew screws..

It doesn't, all aircraft are kept moving by magic, everyone knows that.

Oh, and aliens.

Seriously tho raaid, I thought you were doing a degree in something nautical?

And you're asking how a propeller works?!
