The Mysterious Floating Ball

Students in Room 206 demonstrating Bernoulli's Principle...the mysterious floating ball!






"Bernoulli's Principle is the principle that allows wings to produce lift and planes and helicopters to fly. There are many factors that can effect the lift produced under this principle, but in order to understand how and why things can effect flight one must understand how Bernoulli's principle works."


Bernoulli's principle works on the idea that as a wing passes through the air the its shape make the air travel more over the top of the wing than beneath it. This creates a higher pressure are beneath the wing than above it. The pressure difference cause the wing to push upwards and lift is created.

When the students blew air into the flex straw, the Bernoulli ball mysteriously floated in the air...how? Can you explain?
