Aerial Screw!

The Aerial Screw designed by Leonardo da Vinci was a precursor of the modern day helicopter. The device was designed to compress air in order to obtain flight. The device uses a screw-shaped sail to drill in the air just as a screw drills into other materials. It consisted of a platform mounted by a helical screw driven by a rudimentary system similar to rubber band-powered model airplanes.

The scientific genius of Leonardo da Vinci is brought to life through 10 articulated models. The inventions that inspired these snap-together replicas are taken from the pages of da Vinci's priceless and awe-inspiring notebooks. All models are made of plastic and require no special tools. Manuals are very educational and teach how these inventions have evolved into what they are today.
