When ice cream is made the old-fashioned way, rock salt (big chunks of salt crystals) is mixed with ice. Only a little water melts before some of the dissolved salt lowers its freezing point. Now when the ice wants to melt, it can absorb lots of heat from the water to do it, and the water still will not freeze.
