The Chemical Truth Behind Onion Tears
The chemical formula C 3 H 6 OS isn't just random letters and numbers—it's the molecular structure of syn-propanethial-S-oxide, the notorious tear-jerking compound released when you cut an onion! The cartoon perfectly captures that moment of scientific hubris when you think you're immune to basic biochemistry, only to be betrayed by your own lachrymatory glands. What happens is that when you slice an onion, you damage its cells, releasing enzymes that convert amino acid sulfoxides into sulfenic acids. These unstable compounds then rearrange to form this volatile gas that diffuses through the air, reaches your eyes, and forms sulfuric acid on your moist eyeball surface. Your body's natural defense? Tears to dilute the irritant. Chemistry: 1, Human confidence: 0.
