As any good chemistry student knows, Dihydrogen Monoxide is a potentially lethal dangerous odorless colorless liquid.

Each year, Dihydrogen Monoxide is a known causative component in many thousands of deaths and is a major contributor to millions upon millions of dollars in damage to property and the environment. Some of the known perils of Dihydrogen Monoxide are:

• Death due to accidental inhalation of DHMO, even in small quantities.
• Prolonged exposure to solid DHMO causes severe tissue damage.
• Excessive ingestion produces a number of unpleasant though not typically life-threatening side-effects.
• DHMO is a major component of acid rain.
• Gaseous DHMO can cause severe burns.
• Contributes to soil erosion.
• Leads to corrosion and oxidation of many metals.
• Contamination of electrical systems often causes short-circuits.
• Exposure decreases effectiveness of automobile brakes.
• Found in biopsies of pre-cancerous tumors and lesions.
• Given to vicious dogs involved in recent deadly attacks.
• Often associated with killer cyclones in the U.S. Midwest and elsewhere, and in hurricanes including deadly storms in Florida, New Orleans and other areas of the southeastern U.S.
• Thermal variations in DHMO are a suspected contributor to the El Nino weather effect.

It's no wonder Penn and Teller were so concerned.  Watch the video, then read more about it below.

Yea.  Water.  Would you have signed?

Also, and slightly more serious, consider this article and how it applies to the common use of Junk Science today, as well as in media spin.

Dihydrogen Monoxide:  Unrecognized Killer
by James K. Glassman
Copyright 1997 The Washington Post Company 

The chemical compound dihydrogen monoxide (or DHMO) has been implicated in the deaths of thousands of Americans every year, mainly through accidental ingestion. In gaseous form, it can cause severe burns. And, according to a new report, "the dangers of this chemical do not end there."

The chemical is so caustic that it "accelerates the corrosion and rusting of many metals, . . . is a major component of acid rain, [and] . . . has been found in excised tumors of terminal cancer patients." Symptoms of ingestion include "excessive sweating and urination," and "for those who have developed a dependency on DHMO, complete withdrawal means certain death."

Yet the presence of the chemical has been confirmed in every river, stream, lake and reservoir in America.

Judging from these facts, do you think dihydrogen monoxide should be banned?

Seems like an open-and-shut case — until you realize that this chemical compound is plain old water (two hydrogen molecules bonded to one oxygen, or H 2 O, which can drown you, scald you or make you go to the bathroom.

Last spring, Nathan Zohner, an enterprising 14-year-old student at Eagle Rock Junior High School in Idaho Falls, Idaho, conducted his science fair project on just this theme. Nathan distributed a tongue-in-cheek report that had been kicking around the Internet, "Dihydrogen Monoxide: The Unrecognized Killer" (from which the quotes above are drawn), to 50 of his classmates.

These are smart kids who had studied chemistry; many of them, like Nathan, have parents who work at the nearby Idaho Nuclear Engineering and Environmental Laboratory. Nathan simply asked them to read the report (which is completely factual) and decide what, if anything to do about the chemical. They could even ask the teacher what DHMO was, but none did.

In the end, 43 students, or 86 percent of the sample, "voted to ban dihydrogen monoxide because it has caused too many deaths," wrote Nathan in the conclusion to his project, adding that he "was appalled that my peers were so easily misled. . . . I don't feel comfortable with the current level of understanding."

Me neither, and it's not just kids I worry about. Nathan's project, which won the grand prize at the Greater Idaho Falls Science Fair, was titled, "How Gullible Are We?" But ninth-graders aren't the only gullible parties. I'm sure that, if Nathan tried the same experiment on adults, he'd find at least as many would want to ban DHMO.

Says David Murray, research director of the non-profit Statistical Assessment Service in Washington, "The likelihood is high that I could replicate these results with a survey of members of Congress."

Murray, whose organization "looks out for misleading science that's driving public policy over a cliff," ran across the Zohner story a few months ago on the Internet. But he writes, "we thought it sounded like an urban myth — too pat, too neat." He discovered from local press reports that it was indeed true. I confirmed it too, after talking earlier this week with Nathan's mom, Marivene, who says that Nathan wants to be "a scientist in the nuclear field," like his dad.

The implications of Nathan's research are so disturbing that I've decided to coin a term: "Zohnerism," defined as the use of a true fact to lead a scientifically and mathematically ignorant public to a false conclusion.

Environmental hysterics — Vice President Al Gore springs to mind — and ideologues in such fields as race, women's issues and economics are adept at using Zohnerisms, with help from the media, to advance their agendas. A few examples:

The breast-implant mania. Dow Corning was driven into bankruptcy through lawsuits over its silicone implants — even though science doesn't support claims that they're dangerous. Marcia Angell, executive editor of the New England Journal of Medicine, cites the problem jurors "have in thinking in terms of probabilities, or in acknowledging the possibility of coincidence."

Research, she says, has consistently failed to find a link between silicone and disease. Yes, women who have implants get sick, but, in a typical study, "the implant group was no more likely to develop connective tissue disease than the group without implants."

White flight. In the headline above an article Sunday about population growth in rural areas, the New York Times claimed, "Hint of Racial Undercurrents Is Behind Broad Exodus of Whites." Steven A. Holmes, the reporter, wrote that studies by demographer William Frey "show that of the 40 fastest-growing rural counties, virtually all are at least 70 percent white."

Shocking? Well, according to the Bureau of the Census, 83 percent of the U.S. population is white.

Finding Zohnerisms in the press, Congressional Record and speeches of administration officials makes a great parlor game. One place to start is the collected speeches of EPA chief Carol Browner, who has used Zohnerisms masterfully to promote expensive, disruptive new standards for particulate matter and global warming — despite evidence from scientists that is, at best, inconclusive.

That's a shame. In a land where technical ignorance reigns and susceptibility to Zohnerisms is high, it's the duty of politicians, journalists and scientists to present facts responsibly and in context.

After all, think what would happen if the EPA really did ban dihydrogen monoxide.
