Assemble your own clock that's driven by gears and springs - no batteries required. Construct-A-Clock is based on the design of the first mechanical clock that was created by the Italian scientist, Danti, in 1350. Learn how gear wheels work, and how clocks operate on the principal of a single pendulum. This unique and interactive project will have your creativity and curiosity ticking!
Construct-A-Clock with easy to follow instructions and colour-coded parts. Parts include: pendulum, gears, springs, bells and buttons. Assembles in approximately 15 minutes with no tools required. The assembled clock runs for more than 8 hours with one winding, no batteries required.
The clock is one of the oldest human inventions used to measure intervals of time shorter than natural units such as the day, lunar month and year! The Pendulum clock in particular was the most accurate method of time-keeping for nearly 300 years until the invention of the Quartz clock in 1927.
