Why Do Onions Make You Cry?
Unless you've avoided cooking, you've probably cut up an onion and experienced the burning and tearing you get from the vapors. When you cut an onion, you break cells, releasing their contents. Amino acid sulfoxides form sulfenic acids. The sulfuric acid burns, stimulating your eyes to release more tears to wash the irritant away.
