presence of dihydrogen monoxide creates havoc in small town "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." thys chemical has known to cause death on inhilatation, depositing itself in lung tissue, causing a sensation similar to drowning... too much of it in rivers can cause water to swell (increase in volume), and in turn flood the nearby areas. and frankly, it has a dangerous sounding name. that aside, it has potential in the sense that it helps in the generation of hydro-electricity, and is vital for life. they say 70% of a human body is made up of dihydrogen monoxide. erm!!! but if the human body is 70% water, and 70% dihydrogen monoxide, that would be 140% in all.... no wonder the average american is obese. sheesh!
