Discover the mechanisms that make a wind-up clock work by making one yourself! Complete kit with instructions. You can do it!
Following the detailed instructions, build a transparent clock and see its interior mechanism in action.
When you wind it up the energy transfers to the cogs while the pendulum controls the speed.
