Academy da Vinci Series Arch Bridge Edukit Scaled Plastic Model Kit

Da Vinci's Arch Bridge becomes stronger the more weight it carries. However, if one key component is removed it will collapse. It was originally intended as a bridge that could be quickly built for military use — removing a single piece of wood while the enemy was crossing could cause the bridge to collapse, drowning the enemy forces.

Build the mechanical inventions of Leonardo da Vinci! Leonardo3 recreates the original designs to produce a scale model that is accessible to all kit builders, from beginner to advanced, and requires no extra tools to construct the finished model.
