Let students explore the principles of physics and chemistry by building their own cola clock. Works without batteries! Everything they need is in this handy kit, including step-by-step instructions. Parts are color-coded and easy-to-identify. Use your favorite soft drink and watch it go to work with the see-through case.

Students not only learn how a clock works, but how liquids conduct electricity. A great science project! Ideal for unit studies, as a supplement for any science curriculum, or as a stand-alone science program for hands-on learners.
