The Aerial Screw—referred to as the first ''helicopter'' design by many—was based on Da Vinci's reasoning that, since air had mass, you could screw up into it, much like we woodworkers drive a screw into a piece of wood. Indeed, the same concept eventually led to the development of rotors. This model is made of natural pine and untreated plywood, and has cool meshed bevel gears that are actually based on Da Vinci's drawings. An engaging kit that would be a great activity for parents and kids, or grandparents and kids to make together. Includes clear instructions and historical information, as well as some theory about how aerodynamics and lift works.

Features:

  • All pieces pre-cut and ready to go
  • Pieces are pegged for strength and accuracy
  • Easy enough (but not too easy!) to make in a few hours

  • Comes with glue, a cotton canopy, and clamps to hold it in place while the glue dries
  • Canopy and support structure are removable
  • Historically accurate (but a bit smaller)
  • Completed model is 14'' x 9'' x 9''
