We make ice cream the old way with a ton of ice, some water, and rock salt. Plunging your hand into that ice bath is something everybody should do at least once. You'll get a new appreciation for the survivors of the Titanic at the very least. It's shocking just how stiff it gets, and how fast. The pain is quite severe after only a few seconds as well. It's hard to imagine anybody surviving when their entire body is submerged in something like that.
