Koontz - The Clock

No one is intimidated by engineering - everyone's impressed with Koontz! Explore the secrets behind simple engineering through nothing but recycled cardboard. Since it does not wind or take batteries it is not an operating clock. Twenty-one heavy duty cardboard pieces build easily into a real clock through a few simple steps. Follow along with the included building guide and you'll realize exactly how clocks work; how the gears make everything move together; and how correct timing depends on the simple factors of size and speed. Then check out the activity guide to learn even more cool stuff about clocks. Once you start building with the Koontz Clock kit, you'll never look at cardboard or clocks the same way again.
