"Some things are hot like a kettle boiling, or a toasted teacake fresh from the oven. Some are cold like an outdoor swimming pool in autumn. But if you think those things are hot and cold, check out the stuff in this book: more like hotter than a sun flare and colder than a polar bear’s paws. Have you ever wanted to walk inside a volcano’s crater? Or look at Jupiter’s icy moon? Explore both ends of the thermometer with this cool flip book. Double the chance to blow your mind with awesome facts!" -- Publisher's site.
