I was helping my mom in the kitchen today, and when I started chopping onions, my eyes started stinging and tearing up. But then I realized something weird – when we eat onions in our food, they don’t make us cry at all!Can someone explain why onions make us cry when we cut them

When you cut an onion with a knife that isn’t very sharp… you’re more like crushing it than cutting it.
The crushing makes the onion juice come out like a spray that fills the air, and then it gets in your eyes that way.
A very sharp knife will cut down on eye burning by a lot.
Onions just sitting there, or being chewed don’t have that happening.. especially if it’s contained within your mouth.
