There’s a use, here. Argonne National Lab knows it. Most people who watch the video below would suspect it. Nobody’s quite sure what that use is, but for now it’s enough to know that it can be done.
By using sound waves, the lab has discovered a way to make solutions containing different pharmaceuticals float in mid air. Dropped from a syringe or even from a spoon, the droplets of liquid remain stationary within the field. As Argonne says on their site, it’s no magic show:
It’s not a magic trick and it’s not sleight of hand – scientists really are using levitation to improve the drug development process, eventually yielding more effective pharmaceuticals with fewer side effects.
