We have a system in our inner ears that keeps track of movement and direction. It does this by sensing the movement of a fluid (called endolymph) that is held inside the ear in three little tubes. Just like water in a glass when the glass is moved quickly, the water will slosh in the glass - just as the endolymph will slosh in your head! The motion is sensed by special little "hair cells" in the tubes. Your nerves send a message to your brain about the motion. When you move around rapidly for a long time, it takes a little while longer for the sloshing to stop. So, even if you've already stopped spinning, the endolymph will keep moving in your head for a few seconds, making you feel like you're still spinning.
