Ban Dihydrogen Monoxide!

I first saw the following text in an e-mail back in 1997. For those of you who have not yet read it, or have seen it and may have forgotten about it, I thought that it might be fun to post it here. It’s a good reminder of the fact that there really are no totally harmless substances. Find out more about the origin of this “warning” at Snopes.com:

BAN DIHYDROGEN MONOXIDE! THE INVISIBLE KILLER!

Dihydrogen monoxide is colorless, odorless, tasteless, and kills uncounted thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance. For those who have become dependent, DHMO withdrawal means certain death.

Dihydrogen monoxide:
* is also known as hydric acid, and is the major component of acid rain.
* contributes to the “greenhouse effect.”
* may cause severe burns.
* contributes to the erosion of our natural landscape.
* accelerates corrosion and rusting of many metals.
* may cause electrical failures and decreased effectiveness of automobile brakes.
* has been found in excised tumors of terminal cancer patients.
