DAN'S chemistry

According to the webpage that i found, onions contain amino sulfoxide which can irritate our eyes and make it tear. The one that causes our eyes to tear is the lachrymal glands above our eyelids that regulate the release of tears. Ity also triggers our nerve of crying to our brain which will then make our eyes cry. One of the ways to prevent our eyes from tearing is by covering it with a safety goggle. :) another way told by a guy was: NO more tears? try chilling your onion.
