The $60 Cooper Cooler Rapid Beverage Chiller chills a beer down to 43 Â°F in sixty seconds. So, at the moderate drinking rate of one beer per 45 seconds, you only have 15 seconds of down time until the next beer is ready. Not too shabby. You just fill the P.O.S. with ice and water, and presto: it rotates your can, all the while hosing the aluminum bastard down with cold water. Of course, if you're looking for something a little more powerful -- something that can cool a beer instantly -- I've got two words for you: witch titties.
