Years ago, I read in a magazine that elliptical motion of atoms resulted in a force. It occurred to me that two synchronized sound sources arranged such that the direction of the sound from each was perpendicular to the other, and with a solid cube placed where the two beams crossed, could generate elliptical motion in the atoms of the solid, if the amplitude of the sound waves was different for each sound source. >When the vertical component of the centrifugal force of the rotating >eccentric load exceeds the weight of the brick, the brick will move off the >ground.
