I once heard that McDonalds’ coke is better than anyone else’s because they super-cool it. Deciding I wanted to try this at home, I created a super-cooler for beer and canned drinks. It works on the principles of conduction and freezing point depression.
Water freezes at 32F or 0C unless you add a solute (anything dissolved into the liquid). The solute (in this case table salt) disrupts crystal formation, thus making it harder for the water to freeze. With a solution you’ll need a temperature of several degrees lower than 32degrees in order to form those ice crystals.
