This follow-up to “The Boy Mechanic (ISBN) – Popular Mechanics” collection of can-do ingenuity from the early 1900s – features over 200 unique toys and games that anyone with a basic tool kit will want to make. There’s amusement for little kids, including a toy donkey that nods and wags its tail; a child’s playhouse and a miniature windmill; items for the great outdoors, from a homebuilt canoe to a diving tower; plus gizmos and gadgets, “scien-terrific” motors and engines, and objects for an older child to create and play with.
