Academy Da Vinci Flying Pendulum Clock Kit ACA-18157

Da Vinci was fascinated by how timepieces operate. 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.
