well how about this substance, http://www.dhmo.org/facts.html
Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid. Its basis is the unstable radical Hydroxide, the components of which are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol
Some of the known perils of Dihydrogen Monoxide are: Death due to accidental inhalation of DHMO, even in small quantities.
Prolonged exposure to solid DHMO causes severe tissue damage.
Excessive ingestion produces a number of unpleasant though not typically life-threatening side-effects.
DHMO is a major component of acid rain.
Gaseous DHMO can cause severe burns.
Contributes to soil erosion.
Leads to corrosion and oxidation of many metals.
Contamination of electrical systems often causes short-circuits.
Exposure decreases effectiveness of automobile brakes.
Found in biopsies of pre-cancerous tumors and lesions.
Often associated with killer cyclones in the U.S. Midwest and elsewhere.
Thermal variations in DHMO are a suspected contributor to the El Nino weather effect.
and if you didnt know DHMO is water.. its easy to shock people by accurate facts, its how those facts are said.. i have had some friends want to ban DHMO, even some politicians wanted to ban it.. but kids are toxic, they smells, and noise, they produce the worst pollution

The leg-pull got so far as a vote having been scheduled for the City Council on a proposed law that would have banned the use of foam containers at city-sponsored events because (among other things) they were made with DHMO, a substance that could "threaten human health and safety
