Introduction: How to Demonstrate the Bernoulli Principle While Simultaneously Playing With Your Food!


Here I teach you how to successfully levitate a fruit using just a blueberry, and a lungful of air.  This is a suggested pastime during a nature-trail walk while foraging for huckleberries, or simply during your next mealtime, when sorting through your dinner plate of peas and carrots.

This does not show where Bernoulli actually applies. The centering force is due to the CURVED air flow around the sphere, NOT speed. Fast moving air stream does not have a lower pressure than the surrounding still air. Bernoulli applies at your mouth, because the high pressure in your lungs pushes/accelerates (increases the speed of) the air into the lower atmospheric pressure outside your lips. The pressure drop speeds up the air.

You've changed the way I teach Bernouli's Principle

Thanks Stoeff!

Wonderful :D
