Coca Cola readying self-chilling soft drinks?

And you thought non-stick chewing gum was the heat. Turns out, Coca Cola may be plotting a new version of Sprite that actually chills itself upon opening. Apparently, the drink has to be kept at a specified temperature before being snapped up, and once the oh-so-thirsty consumer pops the top, "a mechanism inside creates ice made from the drink, so it is not diluted." Reportedly, the beverage would sensibly be called Sprite Super Chilled, and if it does indeed hit the UK (and prove successful) by "early next year," the technology could then be passed along to Coke, Diet Coke or even "super cold alcoholic drinks, particularly beers."[Via Tech Digest]
And then someone will claim it causes cancer....
No it will just continue circulating throughout your body till it lowers your core temperature, at which point you die of "brain freeze".
i figure that the increased consumption of Sprite this will cause will give you cancer. Let alone the alcoholics it will create if they can do the same with beer.
True.
"the drink has to be kept at a specified temperature"
What? Why not just avoid all the complication and make that "specific temperature" like 40f?
Oh man, when you filter out all the Apple crap all of a sudden cool news like this one appears. Nice.
@E71
Word.
"What? Why not just avoid all the complication and make that "specific temperature" like 40f?"
Because given standard room temperature, it costs more energy to keep something at 40 degrees than at a higher temperature.
In my fridge at home, If I keep my coke at a certain level, it will become all icey and slushy when i open it up. Before that it's all pure runny and watery. So I have this very situation in my own fridge =)
will be found to cause cancer in 3 years
lol, wow, what are the odds...
I don't even want to know what chemicals they're going to use to accomplish this.
No kidding. Plus- we're finally getting people to recycle. I wonder how this will impact that.
lets just all hope SONY isnt involved otherwise there is gonna be an outbreak of bottles exploding when people go to open the bottle.
CAUSES CANCER!
damn... why am i allways late with these things :(
Looks good though, but i'm guessing that (besides the cancer) there are some other things in there which aren't too good for the enviroment.
A regular bottle of soda will do this today if it is chilled to 32 degrees or so which is what it sounds like this special vending machine will do. The pressure release what the top is opened lowers the temperature a couple more degrees which turns it into a iced slush consistency. Neat idea but not very revolutionary....
But... if the machine keeps it at 32F, then WHY would they need it colder?
that's already a good if not bit low temp for a soda...
I think its COOL
Instantly ice cold beer? Where do I sign?
Word!
Hell might even be worth the cancer.
Gentlemen, the gods of frosty brews have smiled upon us today!
Can you IMAGINE the tailgating possibilities? No more carrying a cooler to the game would be sweet... just snag the case and you are good to go.
Sign me up.
What was that cancer drink by Coke, Dasani water?
So if you gulp it down fast enough after you twist open the bottle, it would freeze your tongue, teeth and everything along the way too?
yes, that would probably kill you...which would probably be good.
As that would mean, all the fat kids who want to drink there sugary goodness and get bigger, will be gone.
Its like a mass cull.
That's incredibly insensitive but it made me laugh.
Wait... if they intend to use a chemical similar to that in freeze packs, isn't that chemical stated to be toxic or non-toxic, but NON-edible? >_>
I hear a lawsuit coming even before the drink is released.
ok... there was obviously not enough information in this article to start saying shit like the chemicals are IN the drink or CANCER or watever. theyve had things liek this before with top ramen type noodles that heat themselves up... the only problem was (as it seems to be in this case) is that unless it was stored at liek room temperature or so, it wouldnt heat up to the right temperature. if it was hot to begin with when the heating started, it would get too hot. if it was too cold to start with, the soup wouldnt get hot enough.
I am glad they are trying it somewhere else first. Cuz if it were here in the states I don't know if I could keep myself from trying it. And I don't wanna die. lol
This will not cause cancer. Likely all they are doing is using thermodynamics to their benifit. This already happens when you through a drink in the freezer, get it close to freezing and then open. The whole drink turns to a slushy. If you control the pressure or the exact temperature, you control the ice formation!
Bingo. It'll be something that uses or enhances the partial vacuum created when you open the bottle. That lowers the temp and "slushes" the top inch or two of Coke. It's awesome when you can get it to happen.
So much for global warming...gotta wait till the earth is at the right temperature...yeah...
If I drop a Menthos into one will it make snow?
I sure hope so :)
wow, snow in the UK...
that would be magic :)
The moment this comes out in the UK, tell us right away and I will personally ship you a pack of Mentos from the state. I can't wait to see you make snow out of this. XD
Surprisingly enough it's possible to find Methos in the UK
But actually, Trebor Soft Mints are just as effective. And more British :D
*Mentos* sorry :p
Actually, if you freeze a sprite or a coke (diet drinks dont work) to a certain temperature just using a freezer, you can make it cold enough that ice wont appear in the drink until you open it and the oxygen hits the drink. It appears as if the drink is freezing right before your eyes and it is totally natural given the temperature of the drink/
@Daniel
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.
Do you honestly think they are sitting around trying to figure out how to give people cancer? There's no way these would go on sale if they weren't safe in the same sense that Coca-Cola is safe.
Well I was making a joke, the joke being that people claim that everything causes cancer.
They're not thinking of ways to cause cancer, they already know this crap can cause it, and THE FDA DOES NOTHING ABOUT IT, ITS ALL ABOUT MAKING MONEY! Same story with the drug companies. They all could care less about our health.
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).
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?
/me kills Chris
8^P
@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.)
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?
Well, if somebody knows the Joule-Thomson coefficient of CO2 at room temperature... (http://en.wikipedia.org/wiki/Joule-Thomson_effect)
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.
