We have observed a clear distinction between quantum turbulence and classical turbulence, which may be explained by the reconnection of quantized vortices. Our recent paper describing the observations has been highlighted as an Editors' Suggestion in the October 10, 2008 issue of Physical Review Letters. The work has been further spotlighted in an accompanying Viewpoint article by J. J. Niemela. The movie to the right shows hydrogen ice particles, trapped on quantized vortices, as they reconnect. Circles have been put to highlight these events. This is the first observation of these events since their prediction by Feynman in 1955. Notice the evident elasticity of the vortices.

Vital statistics: you can read a quick construction summary of our three meter experiment in the “Extreme Machines” section of the September 2008 Popular Mechanics.

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. See our photos! And don't forget the science: these vortex cannons demonstrate many of the principles at work in our studies of superfluid vortices.

We've added a new section to our site, Interesting Data, for sharing past experimental data that may be of interest to the scientific community. A few data sets are posted already and more will come soon. Feel free to take a look—we welcome collaboration.
