How Thick Is The Head?
When I first started ordering Guinness in pubs, I noticed the shamrock contour in the head that the bartender would make with the tap.
Someone said that the head on Guinness could actually support a dime. Do you think that's physically possible with any coins, or was it just time for another round?
I don't think the foam could hold one, but maybe a larger, flatter coin. Dang, now I'm going to be dropping money in beer all the time.
I've heard the same rumor, but never tried it. This sounds like a scientific reason to visit the pub.
i heard something similar where the head should support a bottle cap.
