Suspending Particles in 3D With Nothing But Sound!

Remember these words....Acoustic Levitation.

From the Hack A Day blog:
  • Using a series of standing ultrasound waves, it is possible to suspend small particles at the sound pressure nodes. The acoustic axis of the ultrasound beam is parallel to gravity, which also allows the objects to be manipulated along the fixed axis by varying the phase or frequencies of the sound. By adding a second ultrasound beam perpendicular to the first it is possible to localize the pressure node, or focal point, and levitate small objects around a 2D plane.

Here is the Youtube video that will blow your mind!
