"the drink has to be kept at a specified temperature"

What?

The phenomenon you are referring to is called supercooling. Why you don't observe it with diet soft drinks probably has to do more with the change in freezing point caused by the lack of sugar rather than the added sugar alcohols (they're in a very low concentration). The soda freezing before your eyes isn't because of oxygen, but because the liquid is disturbed enough to form an ice nucleus. See http://en.wikipedia.org/wiki/Supercooled for a description or http://f0rked.com/articles/supercooling for some neat videos.]]>Sep 18th 2007 12:32PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/Sep 17th 2007 4:10PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/Sep 17th 2007 4:49PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/Sep 18th 2007 12:55PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/
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).

No chemicals, no magic... just physics!]]>Sep 17th 2007 4:06PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/Sep 17th 2007 4:13PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/

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 ]]>Sep 17th 2007 4:59PMhttp://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/http://www.engadget.com/2007/09/17/coca-cola-readying-self-chilling-soft-drinks/
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.

Any other thermodynamics hobbyists out there?
