    Why Do Bubbles in Guinness Sink?

    When you pour yourself a nice pint of Guinness, there’s only one thing running through your mind, right? As the brew settles, why do the bubbles sink down instead of rising up?!

    Okay, so the “Guinness cascade” may not have been your primary concern, but the gravity-defying bubbles did intrigue a few mathematicians at the University of Limerick, who explored how the shape of the Guinness glass affected the flow of bubbles in an article they posted at the pre-print arXiv.
