1, cut onions in running water. Cutting onions in running water can control the volatilization of gas in onions, but although it does not irritate eyes, it is a waste of water. This trick is not recommended.

2. Put the onion in the refrigerator and refrigerate it. Before cutting the onion, put it in the refrigerator, take it out after 5- 10 minutes, and then cut it, the pungent smell will evaporate less, and there will be no tears when cutting it again.

3. Chew gum. There is a small hole in the lower eyelid near the bridge of the nose, which communicates with the bridge of the nose and throat to discharge excess tears. When cutting onions, the pungent gas stimulates the eyes, and the tears secreted by lacrimal glands increase. When chewing gum, the upper and lower jaws keep opening and closing, which will form negative pressure inside and suck tears into the mouth through this small hole. So there are no extra tears in your eyes, so you won't cry.

4. Bite chopsticks. When cutting onions, put chopsticks horizontally in your mouth, so that tears will not flow out, because the mouth with chopsticks will become dry and saliva will be secreted in your body. Compared with the tears flowing out when cutting onions, saliva will flow out first, so it has the effect of restraining tears.

5. Soak the onion in cold water. If you don't go into the refrigerator, remove the onion head and tail, cut it in half and soak it in cold water for 10 minute.

6, microwave heating for 20 seconds. Put the onion in the microwave oven for 20 seconds before cutting it. Please wrap the onion in plastic wrap and heat it. It is said that heating can spoil the irritating ingredients in the onion.
