Re: This one is for Acebird
That has to do with the depressurization and the release of gas out of the liquid. I know water has to loose energy at the 32F mark before it will freeze but at -20C I would think that it would freeze if it were as still as being in a bank vault. It also does not look like the water is frozen hard in all the videos because I do not see the bottles expand or break. It looks more like slush what I would expect to see around the 32F degree mark.
