ALISO VIEJO, Calif. (AP) - City officials were so concerned about the potentially dangerous properties of dihydrogen monoxide that they considered banning foam cups after they learned the chemical was used in their production.
Then they learned that dihydrogen monoxide - H2O for short - is the scientific term for water.
