Magic Floating Balls - Bernoulli's Principle and the Coanda Effect Explained

Factamero_ on Instagram: "At first glance, it looks like magic — a ball floating in mid-air, held only by a stream of water. But what’s happening here is pure physics. Fast-moving water creates an area of lower pressure around the ball, according to Bernoulli’s principle. At the same time, the water stream “sticks” to the surface of the ball due to the Coandă effect. These forces balance gravity and keep the ball stable, even when the flow changes slightly. This same physics is used in aircraft

Coandă disk trial (Bristol 2001): fan feeds rim vents, Director shifts flow. Coandă effect turns small pressure changes into lift + spin torque—no wings, no prop pitch. Just airflow steering the craft. What else could be controlled like this? 14 year old video of Bob Collins
