The Magic School Bus meets The Way Things Work in this kid-friendly guide to understanding the physics of sound, perfect for budding engineers.

The Invention Hunters travel the globe in their flying museum collecting the world's greatest inventions! This time, they've landed at a music store, and these silly scientists think they've collected incredible specimens of trampolines, birdhouses, eyeballs, and even a unicorn horn. But what they really discover--with a kid as their guide--is how musical instruments, microphones, and records produce sound.

Using simple explanations and diagrams, and a heaping helping of humor, the Invention Hunters make the perfect companions for curious kids who are ready to learn about science, physics, engineering, history, and more.
