Academy 18157 DaVinci Flying Pendulum Clock

Not your ordinary educational models, the da Vinci kits are based on the early designs of Leonardo da Vinci. The Flying Pendulum Clock needs no glue, paint or battery to finish and operate. Easy to build, it delivers a learning experience during assembly, and serves as entertainment when watching the completed timepiece operate. Da Vinci was fascinated by how timepieces operate. Based on one of his sketches, it uses the laws of motion and a vertical flying pendulum escapement to keep accurate time.
The pendulum's weights, in a bucket suspended from a crane-style arm, act as the clock's power source. The weights propel the pendulum from vertical post to vertical post. As it flies it turns precision gears which in turn keep time. To speed up or slow the clock, adjust the weight-balance of the pendulum by adding or removing weights.

In addition to many iconic works of art and inventions, the restless mind of Leonardo Da Vinci (1452-1519) was frequently occupied with adding to his voluminous notebooks, filled with designs for machines and structures. This model kit reproduces one of those designs -- a flying pendulum clock! The pendulum's weight acts as the clock's power source. This kit assembles without the need for glue, and instructions in English are included.

This is an assembly kit of a space exploration vehicle or other non-fictional mechanism.
