Maryland Day 2008

Fun with fluids at Maryland Day 2008! We built two large vortex cannons, ordered some theatrical smoke machines, and set it all up in the sun for a few thousand of our closest friends. Smoke rings rolled across the Physics Building lawn and a good time was had by all. And don't forget the science: these vortex cannons demonstrate many of the principles at work in our studies of superfluid vortices.
