Single Can Cooler   (+2, -1)  [vote for, against]
Instantaneous Cooling Machine

A device that cools normal 12 oz aluminum cans instantly. Thermo-conductive metal alloy jaw clamps its fingers around the can. Three segments to the jaw, think really big drill press chuck. Super-chilled liquid is pumped through the thermo-conductive jaw segments removing heat in 5 seconds, on demand, to whatever temperture you dial-in to the machine.

Cold can in 60 seconds, not 5, but economical. http://www.cybercan...20Can%20Cooler.html

I've seen this for chilling a bottle of white wine. No idea how it works without shattering the bottle.

single can coolers already exist. Don't know how they work but they exist already. probably through peltier modules, maybe coupled with super- cooled liquid.
