Did you know that a cheetah and a Porsche can both accelerate from 0 to 70 mph/112 kph in just three seconds? That the moon is only slightly narrower than the width of Australia? That the tallest tree in the world, the giant sequoia, is the same height as a 26-story building? Or that length of a blue whale is the same as 19 humans swimming one behind the other? This exciting picture book for curious kids measures and compares a huge variety of different subjects: the strongest animals, the biggest poopers and eaters, the amount of water in the oceans, the most deadly creatures and disasters, extreme journeys, altitudes and depths, the power of natural forces, dimensions of manmade structures, speeds of the fastest vehicles, and the capabilities of super machines. Absorbing, entertaining, and surprising, you'll never look at the world in the same way again once you've read this book!
