A Selection of the Scientific American Book Club   Want to add more excitement to your life?   This daring combination of science, history, and DIY projects will show you how. Written for smart risk takers, it explores why danger is good for you and details the art of living dangerously.   Risk takers are more successful, more interesting individuals who lead more fulfilling lives. Unlike watching an action movie or playing a video game, real-life experience changes a person, and Gurstelle will help you discover the true thrill of making black powder along with dozens of other edgy activities.   All of the projects—from throwing knives, drinking absinthe, and eating fugu to cracking a bull whip, learning bartitsu, and building a flamethrower—have short learning curves, are hands-on and affordable, and demonstrate true but reasonable risk.   With a strong emphasis on safety, each potentially life-altering project includes step-by-step directions, photographs, and illustrations along with troubleshooting tips from experts in the field.
