In a preceding guided tour, Leonardo da Vinci and his sketches and ideas are the centre of attention, which convey a feeling for him as a universal genius. Additionally, the complexity of his war machines, flight devices, lifting devices and further models is clarified. In the subsequent workshop, the participants face the following challenge: a pile of wood, no nails and also no hammer. But one must cross the river as quickly as possible. How is that supposed to work? The participants must solve this task as a group and rebuild Leonardo’s famous bridge together.
