Dihydrogen monoxide parody story has since been used in science education to encourage critical thinking and discussion of the scientific method. A 1983 April Fools' Day edition of the "Durand Express", a weekly newspaper in Durand, Michigan, reported that "dihydrogen oxide" had been found in the city's water pipes, and warned that it was fatal if inhaled, and could produce blistering vapors. The first appearance of the parody on the Internet was attributed by the "Pittsburgh Post-Gazette" to the so-called "Coalition to Ban Dihydrogen Monoxide", a parody organization at UC Santa Cruz following on-campus postings and newsgroup discussions in 1990.

Dihydrogen bond Dihydrogen bond In chemistry, a dihydrogen bond is a kind of hydrogen bond, an interaction between a metal hydride bond and an OH or NH group or other proton donor. With a van der Waals radius of 1.2 Å, hydrogen atoms do not usually approach other hydrogen atoms closer than 2.4 Å. Close approaches near 1.8 Å, are, however, characteristic of dihydrogen bonding. An early example of this phenomenon is credited to Brown and Heseltine. They observed intense absorptions in the IR bands at 3300 and 3210 cm for a solution of (CH)NHBH. The higher energy band is assigned to
