In a world of dazzling extremes, Smarties Wacky World looks at why our planet is such a beautiful, mysterious and very funny place to live. Did you know? The highest ever wave was over 85m high; The Earth"s core is hotter than the surface of the sun; The largest snow flakes that have ever fallen were 38cm across and 20cm thick; We dig deep underground to see what Earth is really made of, climb the world"s soggiest mountain, where the rain stops for just ten days each year and visit the driest desert, where it hasn"t rained for centuries. We learn about the powerful forces of nature, the highest mountains, the tiniest atoms, the fastest speeds. Then journey into outer space in search of black holes and extraterrestrial life.
