Re: SCOTUS Biased Against Basic Mathematical Arguments

Also, you need a lot of salt to get water to freeze at -20C (about 25% in mass), so it's probably not that cost effective unless in bulk. Regarding food, usually you want either to refrigerate (coldest possible without ice crystals forming, breaking tissue and changing the texture) or to freeze (the...
