Sooo elemental mercury. Not absorbed well in the GI tract. I had a patient who took time cracking open thermometers from boilers for a while and then attempted to drink it mixed with some coffee to commit suicide. We show up since he called 911 and now wanted to go to the hospital. Call poison control for recommendations for local hospitals since this isn't common and i don't know what hospitals can handle this thing. Poison control cites that it isn't well absorbed, if at all, in the GI tract. I was pretty surprised.
So really you could drink it and find out the taste with very small if any repercussions.
Yeah elemental mercury ain't that bad. It's all those organic compounds of mercury that are the baddies.
And.... you know, shiny poops that hit the bottom of the bowl with a THUNK , that would be something different. You'd literally lose a few pounds every time you went to the toilet.
