Description:A beach ball can be floated in the air stream provided by an air blower or vacuum cleaner. The ball remains in the air stream even when the air stream is significantly tilted. As the air flows past the ball, the air flow curves around the surface of the ball, due to the Coanda effect. The reaction force on the ball levitates the ball in the airstream.
