Optical rotation

Optical rotation is a big word that explains what happens when we put certain things in water.

Let’s say you have a straw that is made of sugar. You know that sugar is sweet when you put it in your mouth, but did you know that it can also do something funny when you mix it with water?

When you put the sugar straw into water, it will dissolve and mix into the water. As it does, the water will start to twist.

Think of water as a big pool, and the sugar straw as a stick that you put into the pool. If you stir the water with the stick, it will start to spin around.

That spinning is called optical rotation. It's like a really strange dance that water does when it meets certain things, like sugar.

Scientists can use optical rotation to help them figure out what type of things are in the water. They can also use it to make sure that medicines are made correctly, or to see if certain materials are pure or not.

So, optical rotation is like a water dance that happens when certain things are mixed together, and it helps people figure out what’s in the mixture.
