3. Problem What can you do when you are cutting onions.

4. Background info. When you cut an onion you break cells. You release amino acid sulforides which forms sulfuric acids. This produces propanethinied s-oxide it goes towards your eyes and reacts with the water in your eyes. You create tears to get rid of the irritated feeling. You can start crying just 30 seconds after you make the first cut.
