Hans Jenny’s Cymatic Soundscapes with Powder

These experiments were performed by Hans Jenny in the 1960s. Here he vibrates Lycopodium,(a fine powder which is actually the spores of a club moss) using audible sound. The powder rises up from the surface of the taut rubber membrane, and creates a variety of amazing phenomena. At certain frequencies, it even assumes a circulatory pattern above the surface of the membrane, both generated and contained by the force field of the sound pulsations.
