About Academy 18157 Da Vinci Series Flying Pendulum Clock

Academy 18157 Da Vinci Series Flying Pendulum Clock Educational Model KitThe 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. Leonardo was revered for his technological ingenuity. He conceptualized, among many others, a helicopter, a tank, a paddleboat, a self-propelling cart, concentrated solar power, a calculator, the double hull and outlined a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime, but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded. As a scientist, he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics, and hydrodynamics.
