ELI5: Why does your vision continue to spin even after you stop spinning?

You know, you get in a swivel chair and spin around really fast and then stop but you're vision still seems to "spin"? Is my brain catching up or something?

Our sense of balance, motion, and direction come from what's called the vestibular system, which is located in our inner ears. Part of this system is 3 small tubules filled with fluid. When when move or spin or change directions, this fluid moves as well, and our brain interprets those signals to determine our orientation and acceleration, sort of like a gyroscope.

When we spin real fast, that fluid in the tubules spins too, and when we stop suddenly, it takes a few seconds for the fluid to stop. Think of it like stirring a cup of coffee. Even after you stop stirring, it takes a few seconds for the coffee to stop swirling and come to a stop. The same thing happens in our vestibular system. Our eyes see us motionless, but our vestibular system tells us we're still spinning, so it causes momentary dizziness until balance in restored.
