Bottle 1474 - Leonardo da Vinci Crossbow in a Bottle

"Leonardo da Vinci Project" - The model is made in a 1.5 liter container and rests on a suitably shaped rummy base. For the realization of the model I used walnut wood, aluminum foils for the arches as well as small stones fixed to the base and small brass rods for the arrows. The greatest difficulty is given by the insertion and fixing of the 16 arches that surround the central wheel which of course must be rotatable, I would also like to emphasize the difficulty of the side wheels and the space occupied in length and height.
