This is an acoustic levitation chamber designed and built in 1987 as a micro-gravity experiment for NASA related subject matter. The 12 inch cubed plexiglas Helmholtz Resonant Cavity has 3 speakers attached to the cube by aluminium acoustic waveguides. By applying a continuous resonant(600 Hertz) sound wave, and by adjusting the amplitude and phase relationship amongst the 3 speakers; it is possible to control levitation and movement in all 3 (x,y,z) axis of the ambient space.
