How It Is Used
Switch on the fan and gently place the ball above the airflow, where it floats in the air stream. Tilting the airflow slightly shows that the ball stays held in the moving air, which leads into a discussion of air pressure, lift and Bernoulli’s principle.
Frequently Asked Questions
What does the Floating Fan Model demonstrate?
It demonstrates Bernoulli’s principle and the effect of air pressure: a light ball placed in the fan’s air stream stays suspended against gravity.
