Yes absolutely salt dissolved into water, is endothermic you can reverse this ...

Thanks.
And so I suspect that salt flats that dry out and then fill up during rain storms will cool off to some extent when getting wet, then reverse as they dry out.
Has anyone measured this? Can we benefit from it somehow?
A simple test of this process occurs daily in hot climates.
Hang a canvas bag off the front end of your ATV. Fill the bag with beer, first soaking the bag with water (urine also works, but it has a distinctive aftertaste).By the time you get to your destination, the bag will be dry and the beer cold.
