Why do onions watery Status?

When you cut the knife through the onion slices, it will tear across the cells, releasing the contents. These chemicals will react with each other to create an eye-irritating gas.

This gas comes in contact with the water covering the eye, creating sulfuric acid, an irritating substance. And to get rid of those intruders, your tear glands go live.

If you do not like to slump when cooking, avoid the face away from the onions, so the gas will evaporate before reaching your eyes.
