Rubber Band Engineer: Build Guerrilla Gadgets from Household Hardware

Handheld Shooters

Bow and Arrow: Branches, sticks, string, rubber bands, pens, rulers, and bamboo skewers can all be used to craft a bow and arrow. This design is one way to do it, and it illustrates the important principles. Like all the projects in this book, it’s built to be as fun and effective as it looks.

Mini Siege Engines

Da Vinci Catapult: This type of catapult derives its name from the extraordinary inventor Leonardo da Vinci. He sketched an innovative catapult design that winds rope around a central drum and stores energy in flexing bows. Although aesthetically pleasing, many model da Vinci catapults have failed to impress—until now. This take on the Da Vinci catapult maximizes the amount of flexing in the bows to deliver a stellar launch while still maintaining the unique double-bow look.

Hydraulic+ Pneumatic Power

Hydraulic Fighting Robots: Yes, it’s just what it sounds like. Here we will design, build, and customize our own hydraulic-powered battling robots! Each robot begins with a basic foundation, but after that it’s up to you to decide how to build to win. Flip opponents over, push them off the table, or devise another wickedly clever way to dominate the battlefield.


Rubber Band Helicopter: We all know those balsa wood wind up aircraft kits. Wind up the propeller, place it on the ground and watch it take off and crash! Taped repairs can only go so far before the plane is retired to a forgotten place. But now, the rubber band helicopter can breathe new life into those dilapidated aircraft parts. Salvage the propeller, some balsa wood, and a couple of rubber bands to create a new aircraft that can fly upwards of 20’ (6 m)!
