The magnus effect, the one that bends the trayectory of a football ball (the round ones, not the other ones, those are rugby) when a football player kicks it in the side, ia used to explain how lift can exist, but you can live without that didactic trick and know what lift is.

Bernouilli is a traditional explanation of lift, and totally unsatisfactory. Newton, however, explains it much better. If the wing pushes the air downwards, the air will push the wing upwards. That's it.
