This is an acoustic levitation chamber I 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(600Hertz) sound wave, and by adjusting the amplitude and phase relationship amongst the 3 speakers; I was able to control levitation and movement in all 3 (x,y,z) axis of the ambient space. This research was used to show the effects of micro-gravity conditions that exist in the space shuttle environment in orbit, but done here on Earth in a lab. This is not "anti-gravity." So don't waste time arguing something pointless.

i square to god i thought it was a dream i saw a ufo and it was making that same sound in the beggining then i had a weird felling of i was weighless then got up the next morning just like that
hope you find the time to answer my questions; 1)what is the upper limits of weight you were able to levitate? 2)what role does the closeness of the walls play, and what would happen if the box was 3 feet, would you just need louder sound? 3)what effect if any, would adding another speaker to the fourth wall have? 4) what is your hones opinion of that "african shaman performing levitation" in the related videos in the sidebar?
