Beer Can Decompression Chamber
It happens to me fairly often that I want to cool down a can of beer quickly and put it in the freezer - but then forget about it. Next day, the can is burst open and the beer is frozen - and once your beer melts, it tastes flat and ugly.
I've heard though that it's not the freezing process that causes the beer to go flat, but that the carbonation gets lost during thawing (when the can isn't airtight anymore). If true, a beer (de)compression chamber might be the answer - put the frozen can inside and save your precious beer from ending up in the sink.
