Discover the science behind batteries with this kit. The chemical reactions taking place will not only help you power the clock provided, but also assist you in telling time accurately. With the use of copper and zinc electrodes and chemical reactions, voltage is generated to power the clock. Try replacing the lemon with a grapefruit, potato or a soft drink, and observe what effects they have as a power source. Next time you run out of batteries, try searching your kitchen first for a natural source of power. Put some zing in the old tick tock with a lemon powered clock today!
