Bah. If you're going for the "fastest" way to chill something like your boil pot, or a six pack, is to use a dry ice/acetone bath.
Mythbusters is pretty sloppy in my view. When they started out they were great, but now they are just acting silly and blowing stuff up. It's not very fun any more. I remember when they said it was "impossible" to create a gunpowder-driven engine. I can prove, with almost no constructing anything, that this is blatantly false. Take a fully automatic machine gun/assault rifle, attach an arm to the bolt, and use the arm to turn a turbine. Voila. As long as you have ammunition and you hold down the trigger, you will generate power via a self-sustaining gunpowder-powered engine.
