What is the inner ear?

Have you ever spun around super fast on a tire swing, stopped, and felt like the whole room was still twirling? Join Mira and Finn as they shrink down and travel deep into the weird, wet world inside your skull to find out why! You won't believe it, but you actually have tiny tubes of secret fluid and thousands of microscopic crystals hiding inside your ears! These amazing 'ear rocks' and sloshing liquids act like a 3D navigation computer to keep you balanced and tell your brain which way is up. Find out what happens when that fluid gets confused, how lightning-fast electrical signals shoot to your brain at 250 miles per hour, and why spinning ice skaters don't fall over on the ice! Plus, discover what happens to brave astronauts when they float in zero gravity and their ear crystals stop working completely! Put your balance to the test, learn some mind-blowing human biology, and find out exactly why we get dizzy. It is going to be a totally spin-tastic adventure!
