What is annihilated?

Imagine you have two special kinds of blocks, one red and one blue. When they meet, poof! They disappear together. That’s what annihilation means, when things vanish because they’re matched up perfectly.

What are the "things" being annihilated?

Think about your toy box. If you put a red block in it and then take out a red block, nothing changes. But if you have a red block and a blue block, and they're meant to be together, when they meet, poof! Both of them are gone.

Why does this happen?

It's like having two friends who really don’t get along. If one friend comes to visit, and the other shows up too, they both decide to go home together, leaving nothing behind. In the world of tiny particles, annihilation happens when a particle and its opposite meet up, just like those mismatched blocks.

So next time you see something disappear, think about that red and blue block story, it might be annihilation at work! Imagine you have two special kinds of blocks, one red and one blue.
