How do pianos work?

Brains On! Science podcast for kids

Behind every piano’s polished exterior are thousands of parts. From keys to strings, they work together to produce a sound.

In this episode, we take a field trip to a piano shop, peek behind the walls at a world-famous piano factory and have an EPIC FIGHTING BATTLE to discover how sound travels. And the Moment of Um answers this question: “Can you really hear the ocean in a seashell?”
