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.
