NARRATIVE
            Standing waves are set up on a vibrating plate which is clamped. Sprinkle a light, uniform layer of white sand on the plate. Apply rosin to the bow and while holding an edge of the plate, draw the bow across another edge. The sand will collect at the nodes of the standing waves set up on the plate. Varying the place where the hand holds the plate will vary the position and shape of the node patterns.
