This floating ball demo shows Bernoulli’s principle and the Coandă effect in action: fast water flow lowers pressure around the ball, while the water stream “sticks” to it, balancing gravity and stabilizing it in mid-air. | Fadhel Mahdi

The Coanda Effect is cool - it describes how air and water in motion follow curved surfaces. So as the air comes out of the leaf blower, it wraps around the curved sides of the bottle and bulb. When combined with the Bernoulli Principle, we get fun floating objects that stay in the air stream. Try it yourself and be sure to tag me, @sciencebob, so I can check it out! #physicsexperiment #chemistryexperiments #coandaeffect #teachersofinstagram | Science Bob
