In this third book by Ben Hillman, young readers will learn and see just how fast something is. By comparing objects such as the Thrust SSC (that's a Thrust-powered Super Sonic Car), an ostrich (don't underestimate the ostrich, my friend!), the human brain, and bamboo,wildly different objects are taken out of normal context and placed next to one another to allow for new and exciting perspectives. So just how fast is an ostrich? An ostrich would beat a top-notch professional cyclist in a ten-mile (sixteen km) race, hands down! While the best cyclists can race at blistering speeds of twenty-five miles per hour, the ostrich can run at forty-five miles per hour!
