Acoustic Levitation: Using Soundwaves to Levitate Liquids

Using two small speakers that generate soundwaves at frequencies "slightly above the audible range -- roughly 22 kilohertz," scientists were able to examine solutions without the risk of them evaporating on contact with the container holding them.

Scientists at Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals. While the connection between levitation and drug development may not be immediately apparent, a special relationship emerges at the molecular level.
