Re: Is it safe to open and consume bloated coke cans?

Additionally check the bottom of the can for the use by date as well just to make sure. Most of the new flimsy thin cans have a use by date stamped on the bottom of the can.

Re: Is it safe to open and consume bloated coke cans?

Aside from them being coke, blech, normally if one drops a crate of cokes on a flat surface from about waist height, a fair number of them will be bloated as the shock will cause the carbolic acid (bubbles) to come out of solution (similar to the shock when you drop ice cubes into a warm glass of fresh coke it will over flow. So dropshock will cause the same effect. the resulting pressure will cause them to bloat the can due to the increased pressure. I sure there is a proper explanation but my chemistry is non-existent so cannot help there. Somebody here will give you a correct scientific explanation I'm sure (I hope).

fwiw, I've seen some of the replies to SG immigration topics on reddit and they are.. way off. I started browsing here years ago because this forum proved to have more accurate info. Also I'm not scared of curmudgeons.

Precisely..I've seen very odd answers there before. Can't quite trust those sources. I mean the demographics of users here have better life experience and are well-educated.
