levitation is one of those conveniences that sci-fi has long promised
us but has yet to deliver, other than magnetically levitating trains.
But at Argonne National Laboratory in Illinois, physicist Chris Benmore
and his colleagues are levitating objects with an unlikely tool: sound.
It's called acoustic levitation, and after breaking your brain with
what seems to be an optical illusion, it's poised to deliver advances in
pharmacology, chemistry more broadly, and even robotics....
