Elenco® Mechanical Butterfly Kit
The scientific genius of Leonardo da Vinci is brought to life through this articulated model. This snap-together replica is made of plastic and require no special tools. Manuals are very educational and teach how these inventions have evolved into what they are today. It is extremely difficult to create a mechanical replica of the natural movement of an animal. The beating of the four wings is particularly complex and daVinci was well aware of how difficult it would be to create this machine; he himself described it in great detail. It is not simply wings beating up and down; its a jointed motion. Whilst beating down, the wings are "Ã…€œflat" in order to push as much air as possible, whereas when they are raised, they are angled so they create less resistance. Ages 8+.
