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.
