Impact craters in granular media

We have studied impact craters formed by dropping a steel ball into a
container of small, loosely packed glass beads. Both the diameter and depth
of the craters scale with the 1/4 power of the impact energy, as expected if
gravity dominates the energetics of the crater formation process. We observe
a progression of crater morphologies analogous to that seen in impact craters
on the moon.
