Build Real Mechanics. Learn Real Engineering.
Turn blueprints printed on cardboard into mechanical toys! Five levels of complexity, super high level of fun!
From Flat Cardboard to Moving Machine
1. Cut and Fold the Blueprints
Learn the secrets to transforming two dimensions into three.
2. Assemble the Parts
The design process makes the mechanics magically emerge in your hands.
3. Learn Engineering
Understand mechanics, geometry, physics and design because you built a machine!
