Self-cooling beer cans

No, it's not just to cool yourself. Our friends over at Engadget recently posted about the new Instant Cool Can from Tempra, a can with a built in cooling system that can drop the temperature of a beverage by 30º F in only a few minutes. The obvious application is beer, and according to Engadget, Miller will be the first to use the cans. The base of the can contains a drying agent that, when activated, causes a gel in the base to draw heat from the can into a heat sink. There's a lot is going on in the bottom half of this can, which explains why it looks like a 16 ounce can but only holds about 10.5 ounces. Obviously these cans will be more expensive, and for only 10.5 ounces of beer, it seems like smaller "pony" bottles are still the way to go if you want your cold one to stay that way until the end. Besides, I don't think anyone really cares what temperature "the champagne of beers" is served at anyway.
