Have you ever wondered what exactly happens when you clap your hands? Where does the noise go, and how does it actually reach your ears? Join Mira and Finn on an exciting journey into the invisible world of sound waves! You will discover that every single sound is really a super-fast wiggle of air traveling at 767 miles per hour—that is as fast as a jet plane!

Get ready to shrink down to a microscopic size and travel deep inside the human body to find out how your ear turns these invisible wiggles into music, voices, and noise. You will meet the amazing eardrum, three microscopic bones (including the smallest bone in your entire body!), and a fluid-filled organ that looks exactly like a tiny snail shell!

Plus, learn the mind-blowing science behind echoes! Find out why thunder always comes after lightning, and discover how incredible animals like bats and dolphins use bouncing sound waves to literally see in the pitch dark! Get ready to explore the coolest, weirdest instrument on Planet Earth: your very own ear!
