Chemical hazard Memes

Chemistry's most devious molecule just pulled the ultimate prank! H₂S (hydrogen sulfide) initially smells like rotten eggs—gross but harmless, right? WRONG. The truly terrifying part is when that smell suddenly disappears. That's not your nose getting used to it—it's the gas literally paralyzing your olfactory nerves before potentially killing you at higher concentrations. It's basically the serial killer of gases: "I'll make sure you can't smell me coming for you." No wonder chemists treat this stuff with more caution than experimental compounds on a Friday afternoon before a holiday weekend!
