Why do onions make you cry?

Onions produce the chemical irritant known as syn-propanethial-S-oxide. Causes tears.

or…

If you don’t cry for them, who will?

I don’t like onions so…

A: Because when I see them in my food it usually mean I won’t enjoy it much, which makes me sad :’(

the only person that I know that onions have no effect on is chuck norris. That might be because his tears can cure cancer.

*falls over with laughter

Onions have no effect on me. But then again I wear contact lenses.

I worked for a chef that told me that older onions have more of that effect, who knows if its true. I’ve also been told that you can put a matchstick in your mouth while cutting to prevent yourself from tearing. This has never worked for me. Goggles work, if you you’re willing to go that far

wearing contacts prevents the “crying”

plastic bag over the head works to. :P

Or fill a bowl with water, and slice them underwater. That should stop the crying also.

Ooh thanks for that ^^
