Subject: Why does putting salt on a napkin prevent a wet glass from sticking to it.

The question came up at a bar as to why a bartender puts salt on the napkin to 
prevent the beer glass from sticking to it.  All they do is sprinkle some on 
the napkin and the cold sweating beer glass will not stick to the napkin.  If 
you have never seen this before I suggest doing some research this weekend :)
