A pint of Guinness isn’t just a pint of Guinness. It’s a playground for thousands of tiny space-age stuntmen, clad in white suits, getting shot gleefully out of cannons and exploding onto enormous black drums. There’s also a large harp inside the pint, along with a bunch of horns and cymbals, so be careful not to choke on them when imbibing. The tagline is, “It’s alive inside.” Which seems ok for a yogurt, but for a beer? UPDATE: David Griner adds: What they’re really illustrating (I think) is the “Guinness cascade,” a strange effect where bubbles on the outside of the glass go down, but bubbles in the middle of the glass go up. It’s somewhat hypnotic, especially on your third Guinness.
