With this more than 40teilig high-quality wooden kit, an arched bridge can be built step by step with the accompanying instructions and this is the sign of Leonardo da Vinci, the ingenious universal scholar.After completion, the bridge reaches a total length of over 1 meter and is surprisingly stable after careful construction. Very quickly one can see that a force exerted from above on the bridge is carried by all components together. In addition, pressure from above increases overall stability. This phenomenon guarantees AHA effects, lasting insights and extends the horizon of knowledge.Convenient:After assembly, the bridge can be easily removed again and the individual parts can then be stowed in the supplied storage box. The storage box is glued together with a little glue and a little skill in just a few minutes. And for those who don't have wood glue at home, we have provided the kit with a wooden glue.This text is machine translated.
