Something really cool from Georgia Tech.

… a small liquid drop is placed on a thin metal diaphragm that is forced to vibrate by an attached piezoelectric transducer. The vibration induces capillary waves on the free surface of the drop that, upon attaining the critical conditions, begin to eject small droplets from the wave crests.

They call it Vibration-Induced Drop Atomization. If the embedded video below fails, check it out on Youtube.
