In 1990 many a man started panicking about the fact that an extremely dangerous substance leading to a lethal addiction was released into the atmosphere. The name of the new hazard is dihydrogen monoxide. In fact it was a joke where the IUPAC name of the water commonly unknown to a wide audience is used. The joke is meant to illustrate the fact how the absence of logic and knowledge and the preconceived analysis can lead to mass panic. The people were convinced in the need of a diminishing or even banning the water usage as its negative effects and potentially dangerous characteristics were described during the campaign.
