You can put away the batteries. This clock is powered by nature. A classic 'alternative energy' device that uses potatoes, lemons, and more to power an LCD clock. Experiment to see what other substances will power the clock and you've got a great science fair idea! An educational lesson about batteries, electricity, and voltage. For ages 8+.
