Description
Make a ball float in mid-air using only your breath!
This simple and fun toy demonstrates the Bernoulli and Coandă effects in an interactive way. Just place the ball in the holder, blow through the mouthpiece and watch it levitate above the nozzle.
Perfect for:
The toy works through a combination of the Bernoulli and Coandă effects. Fast-moving air around the ball creates a lower-pressure region that helps keep it suspended, while the airflow tends to follow the curved surface of the ball, helping stabilize it within the air stream.
Have fun and don't forget to post your make!
