The Dihydrogen Monoxide (DHMO) hoax is a classic scientific parody that describes water using intimidating chemical terminology to highlight how easily scientific facts can be misrepresented. Originating in the late 1980s and popularized by Eric Lechner and Nathan Zohner in the 90s, the prank lists 'dangerous' properties of DHMO—such as being a major component of acid rain or causing excessive sweating—to trick people into supporting a ban on H2O. Today, the meme serves as a humorous commentary on chemophobia, media literacy, and the importance of critical thinking when presented with scary-sounding technical data.
