I’ve heard of salt water making things colder faster, but not colder for longer, since wouldn’t salt water lose heat (melt/get warmer) at a faster rate than regular water?

You and me both. I never did get the science of how the ice cream maker Ms. Wallace brought in in grade four worked. Might as well have been magic.
