Why Do Onions Make You Cry?
"Why do my eyes water when cutting onions?"
๐ก Simple Explanation
Onions are chemical tricksters! When you cut an onion, you break open tiny pockets filled with a special chemical. This chemical floats up into the air and reaches your eyes. When it touches your eyes, it turns into a mild acid! Your eyes don't like that, so they make tears to wash it away. The onion developed this as a defense against animals trying to eat it. Chilling onions before cutting can help because cold slows down the flying chemicals!
๐ Fun Fact!
Scientists created a tearless onion by turning off the gene that makes the crying chemical!
