Chladni plate
A thin metal plate is attached at the center to the drive post of a transducer of an electromechanical driver. The driver is used to excite vibrations in the plate and is driven by a function generator through an amplifier. Sprinkle fine white sand on the plate. When the signal sent by the generator is one of the resonant frequencies of the plate, the sand forms the nodes in the vibration pattern.
