And this is why we love Mountain Dew

However, to the main topic; http://www.snopes.com/medical/potables/m...wmouse.asp

I meant "Don't drink the coke with the coin diluted in it". You'd be surprised how strong the acids in your stomach can be, and you produce them yourself.

Coke is fine by itself. But I wouldn't drink a coin.

And about the coin, one hour can clean it if it's filthy. After that, it'd start eating it. And I'd try it myself, but the coins that worked for sure had a lot of stain I think, and were made like 20 years ago... So it's quite a collectors coin nowadays, kinda, not so much some time ago. And it was actually hard to find now, because somehow, the metal value of the coin became more valuable than the coin value itself, so some people decided to melt them and sell the metal in bulk.
