What do kids love more than folding paper airplanes? Flying paper airplanes! This book teaches kids why paper airplanes fly the way they do depending on their shape and size. They learn that curling up the back two corners of the wings can make certain airplanes to do loops. They learn that smaller planes can fly straight, far, and fast. This book encourages kids to use their imagination to create their own paper airplane variations based on the models in the book.
