Drop Everything

Remember how, once upon a time, you were taught that there are three phases of matter (solid, liquid, and gas)? Check out this video of an iron ball falling into dry sand. Worth going to full-screen mode (second button, lower right corner).

While of course this makes me realize, once again, that nature is more complicated than my first couple of science classes indicated, it also makes me think it is simpler, somehow, at some deep fundamental level.

Another way cool vid, short discussion, and links over at Cosmic Variance.
