A video camera, recording at the same speed as the soundwave, to make the water look like it's not moving BUT
How the sound makes the water stair-step is a mystery http://games.yahoo.com/blogs/plugged-in/......014.html

I suspect the effect is not as amazing without the 24 frames per second camera shots. This is a similar principal to what Edgerton did with the strobe light
