Using nothing more than a container of loosely packed sand and a falling marble, a research team led by University of Chicago physicist Heinrich Jaeger has discovered a new state of fluid matter.

Why doesn’t air pressure just blow the sand grains apart? “One of the biggest questions that we have still not solved is why this jet is so sharply delineated,” says Jaeger. “Why are there these beautiful boundaries?”
