Onion Sting Grenade

I hate cutting onions. They always sting my eyes while cutting. I thought I could avoid the sting by chopping it in my food processor. Worked ok but when I opened it, it was like an onion grenade went off. The vapor had become super duper lethal and stung my eyes worse than cutting it by hand. 

Onion Sting Grenades would be the worst grenade blast to be caught in.
