dihydrogen monoxide

water, H2O

dihydrogen monoxide: It's more commonly known as water. You know, the substance that every single living being relies on to survive? The origins of this item are multifold, from flyers circulated at the University of California at Santa Cruz in 1989 (so 20th century!) to a junior high school student who surveyed 50 classmates in 1997 and got 43 of them to sign his petition to ban the chemical. He then won a prize at his science fair for his project, called "How Gullible Are We?" Several Web pages touting the chemical's dangers are still live. Don't feel too bad if you've ever fallen victim to this hoax; even a government official in New Zealand took the bait last year.

Dihydrogen monoxide

Dihydrogen monoxide (DHMO) is a combination of 2 hydrogen and 1 oxygen (di = 2, mon = 1), which creates H2O. It is a completely safe element, but a hoax that was created in the 1990's as an April Fools joke got popular that said that DHMO was a chemical that was a substance that was contained in things such as acid rain, nuclear power plants, etc.

John: "Have you heard about the chemical Dihydrogen monoxide? I read that it was really dangerous and it's even in our water and food!"

Steve: "No, that is just water. Do more research and don't believe everything you read online."
