Why do onions make you cry?
Cutting through the cells in an onion allows previously separated enzymes and amino acids in the onion to come into contact with each other, triggering a cascade of chemical reactions. It results in the formation of something called syn-propanethial-S-oxide, a chemical which easily vaporizes and irritates the eyes. The only sure-fire way to prevent onion tears is to wear swimming  !
