With this high-quality wooden construction kit, consisting of more than 40 parts, you can build an arch bridge step by step using the included instructions, all in the spirit of Leonardo da Vinci, the brilliant polymath. Once completed, the bridge reaches a total length of over 1 meter and is remarkably stable after careful assembly. It quickly becomes evident that any force applied from above is supported collectively by all the components. Moreover, pressure from above even enhances the overall stability. This phenomenon guarantees "Aha" moments, lasting insights, and broadens the knowledge horizon. Practical: The bridge can be easily disassembled after construction, and the individual parts can be stored in the provided storage box. The storage box can be assembled in just a few minutes with some glue and a little skill. And for those who don't have wood glue at home, we have included wood glue with the kit.
