A hundred tear-out sheets, each one printed with its own design and its own fold lines, so a child who cannot yet follow a diagram can still finish a plane that flies. Four models to work through, from fighter planes to space rockets to some distinctly creepy flying bugs, each with its own instructions.

Sam Baer designed the folds; the paper does the rest. Two hundred pages means it lasts through a wet week rather than an afternoon, and the tear-out format means the book does not have to be protected from the child using it. Usborne grades it six years and up.

Two hundred pages, 177.5 by 222.7 mm, published by Usborne.
