This experiment is the Chladni plate experiment. It uses a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First add sand to the plate then begin playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand “falls” into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.
“Cymatics” reveals a strange & beautiful symmetry at work in nature. Inspired by the work of Dr Hans Jenny, the images mirror the symmetries found throughout the natural world, from the hidden shapes buried within snowflakes to the massive hexagonal cloud formations found on Saturn.
