From CNN: LONDON, England (Reuters) -- People celebrating St. Patrick's Day Wednesday can cross one topic of conversation off their lists. Guinness bubbles really do sink. Scientists said Monday they had finally proved that the dark stout's creamy bubbles defy expectations and flow down instead of upwards. "Our group carried out preliminary experiments at a local pub a few years ago, but the results proved inconclusive," said Dr. Andrew Alexander, from the University of Edinburgh's School of Chemistry. They first thought the dark liquid flowing down as a pint was poured gave the illusion the bubbles were going down as well. Rest of story is here... Mmmmmmm..... Guinness....... <homer drool sound>
