Hold on to your wand, Harry Potter: Science has outdone even your best "Leviosa!" levitation spell.
Researchers report that they have levitated objects with sound waves, and moved those objects around in midair, according to a new study.
Scientists have used sound waves to suspend objects in midair for decades, but the new method, described today (July 15) in the journal Proceedings of the National Academy of Sciences, goes a step further by allowing people to manipulate suspended objects without touching them.
This levitation technique could help create ultrapure chemical mixtures, without contamination, which could be useful for making stem cells or other biological materials.
