Paper is amazing stuff. It's cheap, easy to use, and easy to recycle. It's lightweight and easy to cut or tear--but incredibly strong when folded, layered, or rolled. It can stand stiff as a board, pop up like a spring, or hang softly like a silk scarf. It's disposable, but it can last for centuries. Its surface can be rough, or creamy smooth, or shiny. Sometimes it's so thin you can see through it; other times, it's thick enough to hold globs of paint. But it can also be beautiful, all on its own. The projects in Paper Inventions were inspired by the many different varieties of paper, from fancy artists' watercolor paper to recycled copy paper, and the many different ways it is used. Whether you like to make crafts or play with electronics, there's a project that will challenge you and unleash your creativity. Projects in this book include: DIY flavored edible paper and ink Paper sensors and switches Paper windmill and paper machines 3D designs with paper Origami and other fold and cut designs

'This is a marvellous book. The diversity of possible puzzles that can be given with these very limited resources, which are basically some paper and scissors, is overwhelming, and the challenges are sometimes very tough. Even the two-star problems may be hard for an untrained puzzler. This is medicine against boredom on long rainy days, but be careful not to get addicted or it may suck up your less empty and sunny days as well.'
