    That was cool, they should have kept going though. Would have been interesting once it got past human hearing and it would just suddenly change in silence.

    Wow, that was really interesting! I never really thought about what sound waves looked like, but apparently they are really neat.

    you need a tight strong piece of rubber (attached to a metal holder, similar to a coping saw shape) a flat piece of metal in the shape in the video, and light sand or something similar. then rub the rbbber bit hard up and down on the edge of the metal. voila, there ya go

    this is basically a sheet of metal (?) vibrated by a speaker I believe; basically a more high-tech version of what is suggested by skittler.

    and we`re looking at standing waves made by the sounds; these only happen at specific frequencies.

    the higher a wave frequency, the closer together the crests and troughs are, so that`s why it`s more detailed the higher it gets.

    See the circles it forms? Well, the higher it is, the more condensed the circles and the more there are. Could those be some kind of particle? Like air or something? Maybe its just my imagination. :P

    There was something similar at the old science museum in Birmingham, but that one you had a bow to use on the edge of the plate. There was a square one and one shaped like a violin. Not as cool as this though!

    The waves on the boards are the resonance frequencies of the board in its vibrational modes, not actually of the sound.

    A certain frequency in the sound will excite the board at that frequency causing some portions to vibrate heavily (non-white sections since the salt is vibrated away) and vibrate non (white sections).

    For futhur imagery, if you keep the board vibrating at a certain resonance frequency, the board will eventually crack at the white line locations just like how bending a paper clip back and forth will break it at the bending point.

    On a note akin to what mogman45 was saying... it`s called crystal harmonics... the theory is, that everything matter in our world has a specific frequency and resonance to it that, if you play the sound loud enough, it almost immediately shatters. Sound waves are pretty powerful things.
