K, some of you need to "chill" with the cancer scares! lol
Here's how they do it: Supersaturate the drink with extra CO2... The same stuff that makes the bubbles in soda/beer. If you put a bunch extra in the drink, it builds pressure. When you open the bottle, the pressure suddenly drops. As pressure drops, the temperature drops as well, cooling the surroundings (in this case, the drink).
1) Temperature is the average random molecular kinetic energy in a substance for a given volume. (Lets say the volume of a liter bottle.)
2) To reduce the temperature, the gas must expand. The measure of temperature now is lower due to the molecular kinetic energy being more spread out. (This is done by twisting off the cap.)
3)Voila, 10 cents of ice cold sprite in a $20 container!
I am going to try to figure out how much CO2 or compressed gas we need to put into 1 liter of sprite (and expand it) to chill it from 75F to 32F. Look for my answer later.
if you read the rest of the press release, the container is made of aircraft grade titanium, retails for $14.95 per bottle or $75 for a six-pack. Also, read the warning label: This will put your eye out.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.

No chemicals, no magic... just physics!
But...doesn't extra carbon dioxide mean it's more likely to spray when opened?
"No chemicals, no magic... just physics!"
Are you sure you don't mean "fizz"-ics?
Yes, I should be pun-ished for that one.
If that's all it is, how come it hasn't been done sooner?

@telp
because the science behind holding such a pressure in has not been there until now.
also, for the original statement, yes that is an excellent idea, and
So lets see...
1) Temperature is the average random molecular kinetic energy in a substance for a given volume. (Lets say the volume of a liter bottle.)
2) To reduce the temperature, the gas must expand. The measure of temperature now is lower due to the molecular kinetic energy being more spread out. (This is done by twisting off the cap.)

Any other thermodynamics hobbyists out there?
Well, if somebody knows the Joule-Thomson coefficient of CO2 at room temperature... (http://en.wikipedia.org/wiki/Joule-Thomson_effect)
