Scientific studies demonstrates that every drink contains a colorless and odorless  substance called dihydrogen monoxide.

                                                          

Some characteristic of the dihydrogen monoxide:

• it is the main component of the acid rains; 
• it is present  in the 100% of the cancer cells;
• it is contained in the exhaust fumes;
• it's a very powerful solvent and it contributes to the ground erosion;
• In solid state it can damage biological tissues like the skin, while in gaseous state it can produce scalds.

Dont'you want a sip of  dihydrogen monoxide?

Despite its danger, this substance is not only contained in drinks and foodstuff but also  in common products like shampoos, floor cleaner, laundry detergent, etc... 

Why governments and global associations don't ban the dihydrogen monoxide?

Many petitions has been made during the years to eliminate this substance from products and food but the governments turned them down. why?

let my give you a clue:

... the dihydrogen monoxide is the iupac name of  WATER!  (zan zan zaaan)

The DHMO hoax was invented by Craig Jackson and it appeared for the first time on the Pittsburgh Post-Gazette and immediately became viral. It bases his fame on the chemophobia  (literally "fear of chemistry")  which is caused by a lack of knowledge  and is often fed by the mass media.

A good example of the success of this hoax is given by an experiment of 14 years old student:

Nathan Zhoner based his science fair project on a warning titled "How Gullible Are We?", presenting "the dangers of dihyrogen monoxide" to fifty ninth-grade students and asking them what should be done about the chemical: 

Forty-three students favored banning it, six were undecided, and only one correctly recognized that ‘dihydrogen monoxide’ is actually plain old water. 

What about you, did you know right away  that dihydrogen monoxide is    water?
