DaVinci Aerial Screw Model

This is one of the flying machines that DaVinci invented, though in reality it would require a huge amount of energy to get working. The logic behind it, however, is quite clear in that it essentially ‘burrows’ up into the air in a similar way to how drill bits burrow into objects. A great gift idea for people who admire Leonardo DaVinci.
