Physics Geek links a video that demonstrates how you can quickly cool a can of carbonated beverage by using a can of expensive compressed air that you should really save for cleaning your computer. You'll also need to drill a hole in a tupperware container, use up some electrical tape, and I hope you have a pair of gloves handy.

Feh.

This is a lot cheaper & requires fewer tools. Forgot where I found it, but I've tested it successfully:

Big mixing bowl, enough water to cover the can, lots of ice, lots of ordinary table salt.

Combine & stir for 2 minutes.

Heat transfer rate is greatly increased by increasing the relative velocity of the cooling medium.

By the way, you might want to wait 20 seconds before opening the can.

Why 20 seconds? Because that's all the longer it takes for a can of soda to settle, no matter how vigorously you shake it. I've tested this one, too. (Credit: Penn & Teller's "How to Play in Traffic").

Please note that the 20 second rule does NOT apply to bottled soda.
