I have had this book since I was about ten years old and it never gets old!! There are so many random facts in here that you can always learn something new. How did Houdini escape? Howcome lightbulbs are so strong? How do they analyze the handwriting of kidnapers? How do people fake UFO sightings? It really is incredible - a must for every inquisitive kid (or adult) on your gift list!

Plain and simple: This book is a must for every human being that can read. Either for rainy Sunday afternoons or for a bathroom book. Get this book!!!

I first saw this book at a friend's house and really enjoyed looking at it. Even children who are not able to read yet can learn lots of things just by looking at the pictures. It tells about everything from the ball in a ball-point pen, to how people figure out what the speed-limit should be for cars on high-ways, etc. I would encourage anyone who likes to learn about different things to pick up this book and give it a try!
