This amazing experiment is called the Chladni Plate Experiment, it uses a tone generator, a wave driver (speaker) and a metal plate attached to the speaker that is covered in salt. At certain frequencies the metal plate vibrates in such a way that it creates areas where there is no vibration, where the salt is then trapped, creating these beautiful geometric patterns. As the frequency increases in pitch the patterns become more and more complex. For more interesting science full of design take a look at Brusspup’s Youtube channel. (via Geddem)
