Bernoulli Effect Display

This video was taken, in HD, by J. Nayes, during the Engineering Expo '09 at University of Wisconsin - Madison. It shows the Bernoulli Effect using a fire hose and a basketball. The fire hose was mounted on a homemade wooden stand and pointed straight up. The basketball was placed onto a wide stream from atop a ladder. The stream was then adjusted finer and finer so that the ball would levitate higher. I estimate the max height of the ball to be ~18 feet high.

This demonstration was put together by the research group led by Ryan J. Kershner, Ph.D.. It was an addition to another exhibit that was put on by Daniel N. Hawk called Micro-Pong, which used holographic optical tweezing to allow people to play the smallest live-action game ever.
