In this mystery story that features interactive puzzles, activities, games, and choose-your-own-adventure scenarios, the reader is led through the steps of writing a book.

“Do It Yourself Bonefishing” is the authoritative guide written for DIY anglers targeting bonefish on the fly. Divided into easy-to-reference sections, this book will help you tackle the why, where, and how of self-guided bonefishing. Informed by twenty years of experience on the flats, Rod Hamilton and Kirk Deeter describe the allure of matching wits with one of fly fishing's most elusive targets and discuss the reasons why more and more fly...

Build your concrete sailboat. Consider the enhanced strength of a concrete shell that has been formed into a curved shape - a feature exploited in many buildings. Then apply basic aerodynamics and vector mechanics to determine how the wind propels a sailboat - sailing with the wind, into the wind, and at right angles to the wind. Try out these points of sail with your model.

Start your project on fixed-wing flight the way the Wright brothers did: by building a wind tunnel. Use it to test different wing shapes at varying angles of attack, exploring the phenomena of lift, drag, and stalling. Your goal is to design a wing appropriate for a low-speed model plane, powered only by a few strands of rubber and flying without remote control.

Put together your model rocket, paying special attention to the engine mount and fins, then giving the completed vehicle a drag-reducing finish. Apply the science of aerodynamics to calculate the required diameter of the parachute. Then check the rocket's stability by determining its center of gravity and center of pressure locations. Your creation is now ready to fly.

Follow the seven steps in the engineering design process to create a golf ball launcher that can hit a target ten feet away. Apply the principle of conservation of energy to select the right steel spring for the job. After building and testing the launcher, consider the joys of do-it-yourself projects and the insights they provide about fundamental engineering concepts.
