A precursor of the modern day helicopter, the Aerial Screw designed by Leonardo da Vinci was designed to compress air in order to obtain flight. Now you can build this model straight from da Vinci's musings and marvel at how ahead of his time he truly was. Snap together assembly, no glue required.
Recommended ages 8 and up.
Made of plastic, the assembled model measures approx. 5" H and 7" W.
Leonardo da Vinci first sketched the predecessor to the modern helicopter in the late 15th century. Dubbed the “aerial screw,” this simple machine was designed to compress air to obtain flight through its unique shape. When originally designed, da Vinci’s helicopter measured more than 15 feet in diameter and was made from reed, linen and wire. The four men depicted on this model represent the original four men in the sketches who stood on a central platform, turning cranks to rotate the shaft. However, due to weight constraints, this model would never have been able to take flight.
A true Renaissance man, da Vinci was everything from a sculptor to a mathematician to an anatomist. He is credited with designing many original prototypes of modern inventions.
