This phenomenon occurs when sound waves of particular frequencies are played through a metal plate causing it to vibrate. If you place salt or a similar grains on the plate, it accumulates in the places of least displacement (nodes). Nodes and anti-nodes occur due to constructive and destructive interference – when coinciding waves either reinforce each other or cancel each other out.  The amazing thing is, as you adjust the frequency of the sound wave, the interference patterns change drastically – with some pretty cool results. These patterns take their name from Ernst Florens Friedrich Chladni who was was a German physicist and musician. I’m sure you’ll agree that this is nothing short of some  handsome science.
