Chewing Gum Prevents You From Getting Tears While Chopping Onions

First the fact why we cry during chopping an onion is that onion while being cut creates a gas which when reacted with water will convert the water into acid.As you have water in your eyes , these water turns into acid and produces irritation to your eyes.Thus tears are produced because of acid secreted from your eyes.

How to prevent it? Will chewing gum really help you out? 

If you are chewing a gum while chopping onions you are most likely away from tears that's because you are breathing through your mouth.This prevents the gas to mix with the water in your eyes.Not only chewing gum helps you to stay away from tears but also there are other few tricks.Let me list them out

1. Chill the onion in freezer for 10 minutes before cutting it.
2. Cut the onion under a ceiling fan.
3. Wear contact lenses while chopping them.
