Curious minds are always interested in what's the biggest and the best, and in a status-driven world, this becomes all-important to even the youngest among us! Now That's Big! offers a high-interest introduction to the sizes, speeds, features, and purposes of some of the world's largest vehicles and machines. Each title includes a brief history and forecasts what the future might hold for these unique crafts. At the end, a comparative pictorial diagram sets the machine or vehicle against other objects or animals to illustrate its relative size and proportions.
