Dacă ști bine engleză îți dau ce ai nevoie: A simple experiment demonstrating the visualisation of cymatics can be done by sprinkling sand on a metal plate and vibrating the plate, for example by drawing a violin bow along the edge, the sand will then form itself into standing wave patterns such as simple concentric circles. The higher the frequency, the more complex the shapes produced, with certain shapes having similarities to traditional mandala designs.
