Warning about DHMO with a "straight face" is just going to scare the OP...
So, because I asked if folks thought that the study was talking about Nalgene bottles, my intelligence is somehow inferior to yours? Just like everything else, one group of "researchers" says something will kill you if you consume it, and another group will say you will die if you don't consume enough of it.
The whole DHMO joke was done many years ago, and the original version I heard was a petition given to people in a mall. This group wanted congress to outlaw all "Dihydrogen Monoxide" because of its dangers. Almost no one got the joke, and tons of people signed the petition. It was done to prove how gullible people can be, and how corny/worthless petitions can be.
