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 via dihydrogen bonding. This kind of H−H interaction is distinct from the H−H bonding interaction in transition metal complexes having dihydrogen bound to a metal. So-called hydrogen hydrogen bond interactions have been proposed to occur between two neutral non-bonding hydrogen atoms from Atoms in molecules theory, while similar interactions have been shown to exist experimentally. Many of these types of dihydrogen bonds have been identified in molecular aggregates. 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
