The Physics of Beer
I’m sure I don’t need to explain why college students would be interested in any video about beer but here’s a new way to think about your Friday-night brew
Take a look at the physics of a pint of Guinness, including the formation of foam, the circulation of bubbles, and the importance of nitrogen and surfactants. The Physics of Fluids paper the host refers to is available here. (And, yes, I will admit to debating the physics occurring in my pint glass while in a pub.) # (via Martin)
