Bernoulli explains the pressure distribution around a wing well. However classic Bernoulli doesn't suggest that air is accelerated - a requirement if you want to achieve lift.
The 'how it really flies' link above is a good treatment of the subject. If you want to get into circulation, rotation, the theory of Kutta etc buy 'Theory of flight' by von Mises.
Back to that teaspoon: have a look how the water deflects the opposite way to the teaspoon...
No flight training program I've seen adequately explains lift.

Reality is that which, when you stop believing in it, doesn't go away.
