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? |
