How to float a ping pong ball on air - The Coandă Effect

The video demonstrates an experiment using a ping pong ball and a stream of air to explore the Coanda effect. The ball floats due to the balance of upward air pressure and gravity. The Coanda effect, where air follows a curved surface, is explained as the reason the ball remains stable in the air stream. The video concludes with an invitation to try the experiment at home.

What happens to the ping pong ball when placed in a stream of air?

Explain why the ball does not move side to side in the airstream.

What is the Coanda effect and how does it relate to the behavior of the ball?

Describe the role of low pressure areas in the movement of the ball.

How does blowing on one side of the ball affect its movement?
