I checked the internet, and couldn't come up with anything.
I drink a lot of Diet-Rite Cola...sometimes two 12-packs a week. What happens is, I'll stock up my refrigerator with a 12-pack, probably purchased from the supermarket a few days prior...and then, the next day, I'll find that one of the cans in the refrigerator has started to cave in.
Now, there's no leaked soda on the refrigerator shelf or on the lid of the can, and there was no leak in the box when I took it out. All the cans were fine when I put them in the refrigerator. That is, they were firm, so to speak. Then, suddenly, they've caved in!
When I pop the top, it's evident that there's no carbonation at all in the can. The soda's totally flat.
This is baffling me. Why was the can "firm" with pressure one day, and soft/caved-in the next? If there was some leak in the pop-top, why did I not hear carbonation being released? Why does it always happen a day or two after I put the soda in the refrigerator? That is, if there was no carbonation in the can to begin with, it should've been caved-in in the box already.
I dunno. This is baffling me. The most recent 12-pack had two cans like this.
Any ideas?

Maybe so.
I'd like to blame my critters, but they can't reach the refrigerator door.
Maybe it's Obama.

From what I've been able to find out, when you rapidly cool a warmed can, the higher pressure of the cold air on the outside of the can vs. the lower air pressure of the warm air inside, causes the can to collapse.
Were the cans fairly warm when you put them in the fridge?
Is your fridge really cold?

Thanks for the 'science lesson', ol'Mule...I was certain some San Franfreako soda distribuitor was messin' with Thor's head and had made a couple of 'cans' out of paper mache.

Yeah, they go from room temperature to the top shelf of the fridge, which is cold enough to sometimes slightly freeze soda (open sodas only). So maybe that has something to do with it.
But still, where would the carbonation have gone? If somehow, the collapsing of the can forced the carbonation out, you'd think that there must be some small rupture in the can's weakest spot, the seam of the pop-top, from which the carbonation could have escaped. I guess it's possible that there's a hole small enough to allow gas to escape, but too small to allow liquid to escape, in which case, it seems that I would've heard some hissing at some point.
Maybe it's just magic.

Hey, wait---re the above theory, it seems odd that a warm beverage going into a cold refrigerator would make a closed container collapse since a warm beverage going into an actual freezer makes it swell and, theoretically, burst. I understand the the formation of ice would make the can expand, but shouldn't it make the can collapse first?
Oh, I dunno. I may just go with the magic/Jesus theory.

Here's another one.
I'll put a room-temp bottle (plastic or glass) of soda into the freezer to get it cold. I take it out after awhile when it's gotten cold. The soda inside is fine. Then I open the top, and ice suddenly forms in the liquid (how much depends on how long it's been in the freezer).
Apparently, exposure to warmer air can actually cause liquid to freeze. Well, that's the way it seems, anyway.

From what I can gather, it sounds like the cans that collapsed were probably defective.
They probably had a bad seal.
Most likely where the top is pressed on to the main cylinderical part.
That probably explains the carbonation loss & the temp change probably causes the collapse.

In which case, I should get a refund. But how do you get a refund on 2 cans out of a 12-pack?
Actually, I wrote to the Diet-Rite people already. I just wanted to know why, not get any freebies. Hell, it was only 25 cents per can. I have a feeling I'll get a coupon or something in lieu of an actual answer, though.

Switch brands of soda.

I'd rather fight than switch. 'Sides, the other brands cost $2 more, so a 50-cent loss doesn't make it worthwhile.
Woe is me.

What about the grocery store brand?
I mean, let's face it.... diet soda is pretty much diet soda.
You probably shouldn't be drinking so much of that stuff anyway.

The contents being warm means they are already expanded. As they cool they contract, creating a vacuum within the can. 15psi does the rest, crushing the can. (Have had 2-liter bottles on the counter expand'n contract like that when the temp changes in the kitchen. The sudden popping noise can get annoying at times....)
It's called hyper-freezing (also flash freezing: http://answers.yahoo.com/question/index?qid=20090417202134AA1fBoX ) It can happen to beer, too. (If a beer company can figure out how to make room-temperature beer turn cold when opened, it'll be the best sales gimmick since bikini models.... ) |
