ELI5: My kid wants to know exactly why she gets dizzy when she spins in circles?

"Is my brain banging around in there?"

There are little tubes inside of your ear that have water in them. Normally, they help you tell which direction you're turning. Try it! Close your eyes and sit in a chair, and have your parent turn you in a circle. You can tell you're turning, right? Even though your eyes cant see anything, those tubes in your ear with the water sloshing around can tell you that you're turning, all on their own!
When you turn around too much in your chair, the water in the tubes gets a little confused. Even when you stop, the water keeps telling you that you're spinning. Basically, because you were spinning for so long, the water in your ear tubes kept spinning even though you stopped. That's why you get dizzy! Your eyes are telling you that you stopped moving, and your ears are telling you that you're still spinning! You're brain doesn't know who to listen to, and you end up feeling dizzy.
