Why Do Onions Make Us Cry?

What Crafty Clover says in this video

Intro

Hey there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do onions make us cry?

The Big Idea

When you cut an onion, it releases a tiny gas that floats up into the air. The gas pokes your eyes, and your eyes try to protect themselves. That is why tears start to flow. It is a funny way for a vegetable to get attention.

You Cut

Step one: you cut the onion. A grown-up uses the knife, of course. Cutting breaks open the onion's cells and mixes chemicals that were kept apart.

Gas Rises

Step two: the gas rises. The mixed chemicals make a stinging gas that floats up toward your face. You cannot see it, but your eyes can feel it.

Eyes Make Tears

Step three: your eyes make tears. Nerves in your eyes sense the gas and tell your brain, something stings! Your tear glands make extra tears to help.

A Closer Look

Let's take a closer look at how tears protect your eyes. First, the gas lands on the wet surface of your eye. Next, tears try to wash it away, and that is why they pour out. Closing your eye helps protect it, too. Each part of your eye is working together as a team.

Quick Facts

Quick facts! A little fridge time can calm the onion. Cold slows down the gas, so fewer tears come out. Crying from onions is harmless, and it stops soon after. And remember, a grown-up uses the knife. Onions use this stinging gas to keep hungry bugs away.

Think Like a Scientist

Now, think like a scientist! With a grown-up, cut an onion near a fan. Have the grown-up do the cutting, while you watch from a safe spot. Notice whether fewer tears fall. Observe, compare, and discover!
