THIS BOOK IS FULL OF HOLES

When you think of holes, what comes to mind? Maybe the irritating hole in your sock or the gap on the shelf where you took out this book. A hole can be surprising, like a sudden sinkhole, or useful, like the openings in airplane windows. They can even save lives, like a seal’s breathing hole in the ice. Investigated by scientists, used by artists, and designed by engineers, holes are essential to our lives, whether natural or human-made, big or small. Explore the fascinating world of holes in this book — take a peek inside!
