Cardboard Box Engineering unit:each critical when bonding dissimilar surfacesYoung makers need projects that actually work, not frustrating failures that end up in the recycling bin. This book delivers functional machines, kaleidoscopes that create genuine optical patterns, marble runs with reliable momentum, robotic hands with articulated fingers, all engineered from cardboard using household tools. Jonathan Adolph understands that building teaches more than following instructions; each project introduces fundamental physics
