The spoon in a stream is more of a surface tension thing and the classic blowing air over a piece of paper is the coanda effect. The total effects of newton's laws and bernoullis law on pressure differences need to. Be combined but the gist is that you create a force difference using the shape and angle of attack of the airfoil. The use of this is really quite neat especially in a printer!
