No I know that much. What I'm saying is, if you happened to keep it warm till you reached the top what do you think would happen if you opened it?
Yay internet! So the adverage coke can has a pressure of 60 psi and can withstand up to 90 psi. The atmospheric pressure at sea level is roughly 14.7 psi whereas the atmospheric pressure at the top of Everest is about 4.89 psi. Bringing a can of coke to the top would increase the pressure in the can to about 70 psi, louder but not explodey. However you have the cold to deal with as well, as the drink freezes the water inside takes up more space therefore increasing the pressure within. To what who knows, but there is one kid in China that had to get 38 stitches on his face after trying to open a can he got out of the freezer. It makes me want to know what the actual pressure is inside the OP 's cans.
You can put a can in a freezer, for a few minutes to make it cool really quick but it's better not to forget it there. And even worse thing can happen with a bottle of champagne. When liquid freezes it expands, turning a bottle into a hand grenade. Which will damage your freezer. Of course it won't explode like every time, in most cases it will simply crack somewhere. But it can, so it's better be careful. Same with overheating. Remember why those pressure cookers are so dangerous when you forget to clean valves? Soda can in a fire makes quite a bang too.
Just one coupon, major corporation could've done more for you honestly. Like when I got food poisoning from McDonalds. All they sent me was a $10 voucher. Told them to shove it, and never returned to that store.
This is how it has been like for as far as I remember. My family had an issue with something being found in a can of Cambell's soup. They sent a well mannered guy in a suit and all we were offered was a small booklet of coupons. Much of which didn't even give a free product, just a cost reduction. Seriously, WTF?
Yup, if the big companies are not required to do something by law they don't give a shit. Not pretty but I guess that's how it works.
