I used to carry a little chrome vile of mercury in my pocket when I was kid to shine pennies with. I also used it once to see if it would turn the filling in my teeth a bright silver like it did pennies. Luckily it didn't or I might have kept them polished with it all the time if it did. I was about 12 years old at the time and now I'm a few months from 60 with no ill effects so far unless you call wearing a tin foil hat strange which I don't think there's anything strange about it since all the other little people here at the home with me are wearing them.
