Actually, I think they just proved that when it looks like the bubbles in a Guinness are going down instead of up... they really ARE going down instead of up.

Of course this has something to do with the fact that they are going up even faster in the middle of the glass and so the flow of fluid pushes down on the bubbles next to the wall of the glass.
