Destin from Smarter Every Day shows us experiments in acoustic levitation.
Acoustic pressure waves are generated to cancel each other out, forming standing waves that create columns with the power to levitate objects whose weights are within the parameters of the frequencies of the pressure waves. There’s a lot of awesome eye candy, here.
One is reminded of course of the alternative theories that a similar technology was used to create the megalithic structures and temple complexes of the ancient world, including the Pyramids of Giza.
