Hydrogen sulfide (H2S), as it turns out is fairly easy to make. The following production method can be made with commonly available chemicals,
ZnS + 2HCl = H2S +ZnCl2,
which is 1-part Zinc Sulfide and 2-parts Hydrogen Chloride (really Hydrochloric acid), when mixed, produces Hydrogen Sulfide and Zinc Chloride.
Zinc Sulfide is a phosphorescent solid, usually a white to yellowish powder, that is commonly used glow-in-the-dark toys, TV screens, and CRT monitors. Though, in these uses, it is usually mixed with copper in order to make the glow effect last longer.
[Note: This is different from glow sticks which involve chemiluminescence. The inner vial contains hydrogen peroxide and the outer tube contains Cyalume and a fluorophor dye.]
Hydrogen Chloride is technically a gas, so what is really used here is hydrochloric acid, which is a liquid (also known as muriatic acid). Hydrochloric acid is typically found in toilet bowl cleaners in order to clean hard water stains caused by calcium carbonate.
Zinc Chloride as a product here, presents itself in liquid form. This chemical has the ability to dissolve starch and is used in Febreeze to dissolve the active ingredient cyclodextrin.
Hydrogen Sulfide is then the highly toxic gas produced. This gas is added in small quantities to natural gas, in order to give it that rotten egg smell (at concentrations probably around 0.01 ppm). Concentrations of 800ppm is the LC50, the leathal concentration that kills 50% of humans exposed for 5 minutes. At concentrations over 1000ppm, a single breath will cause one to collapse and lose consciousness, and even if no longer exposed to hydrogen sulfide, death is imminent.
How one extracts the key ingredient, ZnS, from a suitable source, shall be my little secret. Needless to say, not much is going to happen if you dump glow-in-the-dark plastic into hydrochloric acid (though the plastic might melt, hah). If you are lucky, you might hear about how I did it in the news.
