I just nominated this for an Ig Nobel Prize.
Reply was: "Thanks! A worthy nominee."
Real Nobel laureates give out the prizes.

finally put this one away, according to three scientists. They claim to
have solved the puzzle of why bubbles in dark beer sink rather than rise,
as common sense, and a cursory grasp of physics, suggest they should.

because they’re trying to go up. But in trying, they create currents
that enable some of them rise only at the expense of other, more clearly
visible ones, which instead drop. The shape of the glass, meanwhile,
plays a key role, said the investigators, who studied perhaps the
best-known brand of stout, Guinness.
