Story

Today with an Arduino, a 3D printer and information found online, its possible to make extroardinary machines.

We built a levitation machine that uses 72 ultrasonic transducers. The transducers work at 40 kHz and can trap objects with a density greater than2.2g/cm3 and a diameter of 4mm.

The levitation of water, paper and styrophoamspheres is possible and shown in this video.
