Break Down! a National Geographic kids book

In this episode of Cool Science Radio Mara Grunbaum who has just written Break Down! which is a NatGeo kids book joins Lynn and John. The book explores how things break down, crack, explode, crumple, and shatter.
Break Down! explores the world through the lens of what it takes for things to, well, not work. You peer through the smoke and rubble of controlled demolitions to discover the properties of building materials. It shows the inner workings of a cracked cell phone screen, mega-avalanches and sinkholes and it travels back in time to explore the world’s most famous failures.
