title: Ball on Air Jet
aka: Bernouli or Venturi effects

Description:
    Moving air, from a hair dryer or a nozzle attached to lab air, supports a ball in air.
The effect is more pronounced when the jet of air is not vertical, and this tends to make the ball spin.

 
Questions:
   Why does the ball not get pushed out of the air stream?
    Why does the ball spin when the jet is not vertical?
