(SNIFF!) Oh, Phil... such devotion to real science is so heartwarming!
I toast you!!!
- Seriously, I witnessed the research that went into an actual paper explaining the behavior of foam when pouring a guinness beer...
There was actually a lot of physics in that ummm 'study', (also a few hangovers....).... Hmm this gets me thinking.... My laser uses about 30 gallons of 190 proof ethanol... maybe there is a paper in that... ;) (or at least a wild keg party!)
