Edu Toys presents the da Vinci Aerial Screw Model Kit. 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 this series of 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. For Ages 8 and up.
