Get the facts on Dihydrogen Monoxide.

If you haven’t familiarized yourself with DHMO.org yet, please do: it’s a invaluable website that gives you the facts about a silent threat.  From the FAQ:

Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid. Its basis is the highly reactive hydroxyl radical, a species shown to mutate DNA, denature proteins, disrupt cell membranes, and chemically alter critical neurotransmitters. The atomic components of DHMO are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol.

To give you an idea of just how widespread this problem is, consider this: when Charles Sullenberger landed his plane safely, his primary concern afterwards was making sure that all of the people in his charge had as little exposure to DHMO as possible – and that plane was positively dripping with the stuff, thanks to the crash knocking things around.

Yes.  It’s that much of a threat to us all.
