You're saying that dissolving calcium chloride is endothermic?

No. What he meant was that the calcium chloride would allow the ice to
become liquid at -50F. This would give an icewater bath.

Pure ice at -50F would be solid, and wouldn't conduct nearly as well due
to air pockets around the can.

However, good luck finding a freezer that will give you ice at -50F...

That's what I figured.
