      I expect this post in a couple days: “How do I remove a paper towel that is frozen to my bottle of wine?”

        We used to put warm beer, ice, and salt in a cooler to cool the beer down quickly on Friday after work. It worked great for that.

      Also it’s not only a higher rate of cooling, but the dryness of the freezer makes some of the water evaporate and carry heat away with it!

      The water has to be cooled too, and there’s still air around it though?

      I guess we’re talking about direct contact, not around a container, otherwise the water turned ice may even serve as an insulator?

        The water creates a better way to transfer heat from the container to the freezer because it has direct contact with the container and replaces the air around it. Yes the water needs to be cooled too, but still the process is way faster because air really is a good insulator for heat. This is why insulating materials for houses e.g. always try to maximize air content (foam, glass wool, styrofoam)

          You also get evaporative cooling, as the freezer is a very low humidity environment. This is accelerating the cooling much more than any thermal conductivity the water adds.

          The reverse process is why humid air makes your beverages get warm quickly when the water precipitates on a cold can/glass.

          N.B. maximize air content while minimising air movement and therefore convection. Otherwise you could just have cavities in your walls for maximum air.
