Quick Answer:The Floating Ball Model keeps a lightweight ball suspended in an upward air stream from a nozzle. It demonstrates Bernoulli’s principle: faster-moving air has lower pressure, which holds the ball steady in the stream.

Key Features
Air is blown upward through a nozzle under a lightweight ball.
Ball floats steadily in the air stream.
Shows the relationship between air speed and pressure.
Ball stays in place even when the stream is tilted slightly.

How It Is Used
Set the blower or nozzle on a flat surface, place the ball above the outlet and start the air flow. The class watches the ball hover, and tilting the stream a little shows how it stays in place. Keep the outlet clear and use the blower carefully.
Frequently Asked Questions
Why does the ball stay in the air on the Floating Ball Model?
The upward air stream supports it, and the faster-moving air has lower pressure, so the ball is held steady in the stream, as Bernoulli’s principle explains.
