| Scientists at the University of Chicago and University of Twente in the Netherlands used high speed X-ray cameras to capture a new state of matter. The experiment itself is simple: drop a marble into losely packed sand. This creates a jet of sand grains that behaves like super-cooled, ultra-dense gas. You can even do this experiment yourself with marble and a cup of sugar! http://www.livescience.com/forcesofnature/051206_new_matter.html |
