I have just recently seen Episoe 29 conserning the activities to cool beer. The night before i saw the episode I was a a friends party and we actually ran into the promblem of the beer being warm. However, my friend just grabbed a arosol can of compressed air, the kind used to blow dust and debris off of your keyboard. He sprayed the can on the bottom quickly and it seemed to cool the can. I thought I would just let you guys know my findings.

Also, placing a beer can in ice water and spinning it as it floats is a good method as well.

Bottled liquid/gas fuel like butane or propane - sprayed - gets super cold as it evaporates and would chill that beer real fast. Very flammable tho. Makes me wonder if they had doused it with gasiline and let it evaporate rather than lighting it ...... but the result with salt and ice is quite cool and safe enough for people who may have already drank several beers already.

I saw that episode too and thought that perhaps they missed something in the setup of the experiment. They said that it was a Vietnam era myth and that the beer was set into sand. I don't think there are any deserts in Vietnam - so it is likely that the sand was at a beach. That means that the beer could be buried in wet sand with gasoline on top. Then the burning gas may force evaporation of the water - thereby cooling the beer. It would also help keep the fuel off the cans since as a less dense liquid it would stay above the wet sand. Maybe this should go to myths revisited.
