Why onions induce tears

Why does cutting onions make you cry? When you cut into an onion, a strong acid sprays into the air. If your eyes are in the way of the spray, which is likely if you are cutting onions, the acid causes your eyes to sting. Immediately, your tear glands go into overdrive, and your eyes start to tear, and tears continue until they have flushed the irritation away. - faqkids.com; science.howstuffworks.com; food-info.net
