Dihydrogen monoxide is a chemical found widely in tap water in the western u.s due to water treatment failure. Dihydrogen monoxide is highly harmful if inhaled, aids in greenhouse gasses, and is found EVERYWHERE in the tap water. please be smart and purify your H20.
Just kidding, well sort of.
Dihydrogen Monoxide is highly harmful if inhaled, aids in greenhouse gasses, and is found everywhere in tap water... but guess what? Dihydrogen Monoxide IS water. just an odd name for it. What i just tricked you with was a common scam to do just that. so just in the off chance come across this trick... don't fall for it.
