How can electrons have half spins?

A teacher told me that electron don’t even really ‘spin’ the way we understand spin. But somehow they can have angular momentum. And what exactly is the concept of half spin?

Imagine you have a toy top that spins around, and you can see it moving in a circle. Now, think about a tiny, tiny marble called an electron. Electrons have something special called “spin,” but it’s not like spinning a top that we can see. Instead, it’s a special way the electron behaves, like a secret trick it can do.

This special trick called spin gives the electron energy and helps it interact with other tiny marbles. Think of it like how magnets stick together or push apart.

Electrons have a special kind of spin called “half spin.” This means they have two special ways they can behave, which we call “spin up” and “spin down.” It’s like having two different moods that the electron can switch between.

So, electron spin is a special trick the tiny marble does, not a spinning motion we can see. This trick gives it energy and two special ways to act.
