Ever wondered how to tie a cherry stem into a knot in your mouth? Always longed to know how to remove the pit of an avocado, milk a cow or perform a face lift? Wordless Diagrams by Nigel Holmes has simple black-and-white diagrams to guide you through the steps. Some are serious, and some are just for fun (“How to make a horse gallop” directs you to make a flip book of a running horse). The diagrams aren’t labeled, so you’ll have to refer to the index or simply try to puzzle out what you’re learning to do. Warning: Try out “How to practice putting your head into a tiger’s mouth” at your own risk.
