This book is a collection of 28 experiments that are not meant to have any practical purpose. Each experiment, however, illustrates a scientific principle and enables students to discover how scientific facts and theories apply to seemingly useless experiments. Each experiment includes a list of materials, a series of steps, an explanation of the scientific principle demonstrated, and a section that offers additional scientific facts and information on each topic. Experiments include: Hockey Night in Canada; Gulliver's Eggs; Slam-Dancing Spaghetti; Pumping Aluminum; Make it Snappy; Rope Roundup; Iron-Poor Foods; Genie in a Bottle; Spongesaurus; Balloons at the Beach; Where's the Beef; Titanic; Less Filling; Glub; Sand Puzzle; Cave-In; A-Maze-Ing Potato; Buttered Up; Electric Pencil; Shake a Leg; Static Fireflies; The Crying Game; A Delicate Balance; Fast Money; Foiled Again; A Very Dry Cell; Smoke Gets in Your Ivy; and Coffee to Go.
