Mythbusters TV show host Adam Savage drops science on how to make a warm can of Coke cold in under 2 minutes over on Ask MetaFilter.

That would be about 20-25 minutes in a freezer. If you put [the can] in a bucket of ice, that would halve that time. If you put water in that ice, it'd be cold (+- 5c) enough to drink in about 4-6 minutes, if you put salt in that water, you'd reduce the chill time to just over 2 minutes. Agitating the can in the water, rolling it around, reduces the chill time even more.



The fastest possible way is to grab a CO2 fire extinguisher and unload that sucker on the can.


While our lawyers tell us not to recommend the fire extinguisher route, salt in an ice water bucket is doable. (And if you haven't seen Mythbusters, you're missing out. That show is a MacGyvering lifehacker's dream come true.)
