It is due to breathing through your nose and the associated odor of the onion. By breathing through your mouth (or gnaw on a toothpick?) you should be able to control the weepy eyes and nose. According to the food channel, it's because when you cut the onion, you pierce the cells which releases a chemical which irritates the pink tissue of the eyes & nose. Which are proximate to the source when looking down to slice & dice. Wanna real treat? Cut up some horseradish, it's guaranteed to run you out of the kitchen right fast!

∙ 13y agoThe reason you "cry" when chopping onions is because onions contain a lot of Sulfur. when you cut into the onion it releases Sulfate gas, which when it reaches the moist membranes of your eyes combines with water (H2O) and creates Sulfuric acid (H2SO4), which is why it stings. Your body then secretes tears to try and dilute the acid which leads to the "crying".

∙ 13y agoTry running the sink faucet next to where you're cutting the onion, and make sure the onion is closer to the running water than it is to your eyes. The sting in onions always travels to the nearest water source (usually your eyes) as soon as you cut it open, so if you have a different water source closer to the onion, your eyes are likely not to sting.

How do you make your eyes stop burning when your cutting onions?
breath through you're mouth.Another AnswerOne thing that helps is to score the first layer and peel it off before you cut and chop the onions. For some reason, this first layer seems to contain the most fumes that make your eyes water. You can also rinse the onion in cold water before you start to cut. It won't make the onion soggy, in fact it seems to make the onion crisper. Good luck. Also, try chewing gum while you chop the onions.
What part of a onion makes you cry?
All onions make you cry, because when you cut them, the enzymes inside combine to make a gas that wafts up from the onion. When the gas touches the water in your eyes, it forms sulfuric acid, which is what makes your eyes cry in order to wash the irritant away. You can avoid this by cutting the onion under water, or chilling it.

Why do purple onions make us cry?
It's not just purple onions. There is a chemical inside of onions that, when you slice an onion, are released into the air. This causes a slight chemical reaction in your eyes, causing a burning sensation. To combat the burning, your eyes tear, causing you to "cry."
