When I was little, I used to believe that salt could absorb water (because eating salt always made me thirsty I suppose). So, I decided to do a little experiment. I took a plastic cup and filled it with water and salt. I left it in one of my desk drawers that I didn't use and forgot about it for years! When I moved, I found it and, alas, the water was not gone. To this day, if you open that drawer, you will smell salt!
