Audio Frequencies Create Amazing Sand Patterns (Video)

We already wrote about Brusspup’s incredible anamorphic illusions and his ability to bend running water with audio frequencies. Now the guy is back with even more amazing resonance trick, called the Chladni plate experiment! This time Brusspup attached the tone generator to a black metal plate and poured sand over it. As the sound frequencies from the speaker make the plate vibrate, the sand gravitates to those areas where there are less vibrations, and creates complex sand patterns. These patterns are never random, and get more complex with the higher frequency. Tempted to try it yourself? (via: Colossal)
