    You can lose your senses in a second ( KNOCK DOWN : Painless!! ) if you inhale [high concentration hydrogen sulfide GAS] over 1000ppm!!!
    You can't "Knock Down" with "chlorine gas"!

    Strong Acid + Calcium Polysulfides solution(Pesticides) = Hydrogen sulfide (H2Sgas)

    • If in a bathroom or a car, enough with each 2 litters (about half gallon).
    • You can use sulfuric acid of a car battery as strong acid, and you can use a pesticide lime sulfur as calcium polysulfides.

    It reachs a fatal concentration over 1000ppm quickly.
