Engineer Tammy Enz illustrates seven projects with photos and step-by-step instructions. One project is “water shoes.” Leonardo da Vinci came up with designs for lots of things, she writes, including shoes for walking on water. Water-shoe inventors need to have a passing acquaintance with the principle of buoyancy, which describes why objects float. And they’ve got to think about ways to spread out their weight. This is a great guide for kids who want to get their “engineering” feet wet.
