Richard, a saturated sodium chloride/water solution freezes/melts at 0 F, which is where that constant came from. If you want to freeze it "rock hard" you will need to get your freezer well below that temperature, which is the general temperature that folks shoot for for a home freezer. But sloppily cold ice cream is good, too. And, as another poster said, it is easy to make ice cream. besides the ice cream mix, all one needs is a suitable bucket, salt and ice. I have a one quart hand crank freezer that is ready in fifteen minutes. Even a small bucket with a bail, set inside a larger bucket, will work. I've used an old fashioned syrup bucket for the ice cream, and a water bucket for the ice tub. Set the syrup bucket in the tub, fill 3/4 full with ice cream mix, fill the tub with ice and salt. Twist the syrup bucket back and forth by the bail. In a little while, ice cream. You'll likely need to add ice and salt periodically, and pour off the meltwater.

One tip from the list was to realize that ice cream at 32 F (as in packed in ice) is not the same as ice cream at 0 F (like in the refrigerator at home, which I assume is something like 0 F).

When it starts to thaw, it will be at much less than 32 F. What's needed is a "phase change", going from solid ice to liquid, that's where the energy is.

(If one exists..) Maybe I should just go with chocolate ice cream...who doesn't like a cold and somewhat sloppy chocolate shake in the middle of the desert...doesn't have to be rock hard, right?
