We keep a ping pong ball on a string near a faucet but not directly under it. When we run the water, the ball moves to the stream and sticks there.
I'm only interested in the moving part not the sticking part (there are lots of explanations for that online).
question1: Why does the ball move toward the water stream?
question 2 If we run the water and get a steady flow first, and then take the ball close to the stream, would it still move toward the water?
