If, like me, you prefer your booze in its native liquid state DO NOT TRY THIS AT HOME. You will end up with a sad flat bottle of swill.

i hope i'm not wrong, otherwise i'll get run over by the sift bus, but i'm pretty sure the explanation is incorrect. i do this with my Smart Water daily at work, and as far as i know, there's no CO2 in my water, releasing pressure.

the real reason this happens is nucleation. though i don't get why the initial rise of CO2 when the bottle is opened does not provide that nucleation. with water, all that is required is a bubble, and the supercooled water will start to form ice crystals on that seed. in the beer's case, this was the sudden formation of CO2 bubbles at the bottom due to the violation of Man-Law (beer tapping). this formed a seed where nucleation occurs. leaving the bottle closed, and simply giving it a quick shake (as i do with my water) should provide the same results.

The vid's explanation is indeed incorrect. Check my tags, thought, I did put supercooled fluid for that very reason.

And and upvote for the Man-Law vid. Never knew it was even in the queue.
