Finally, a chance to play with your food! -- Learn about electricity and chemical reactions in an innovative way. -- The Two Potato Clock allows you to generate enough electricity to run a digital clock - using potatoes! Just push the zinc and copper electrodes into the potatoes causing an oxidation/reduction reaction that is converted to low voltage. -- You can also try other fruits, vegetables and beverages to see what works like: -- Apples -- Avocadoes -- Bananas -- Cucumbers -- Lemons -- Lines -- Oranges -- Salt Water -- Soda -- Tomatoes -- Powers a ½" high LED clock. 5 ½" x 9" x 2 ½".
Not your standard garden-variety timepiece, this unusual digital clock harnesses the power of potatoes. Safe and easy to operate, the Two Potato Clock works by capturing electricity created by a chemical reaction inside of the potato. Sure to turn heads at the office, and a great conversation starter at home, the clock never requires any batteries--only a fresh set of tubers (any variety will do) once in a while. In the event of a potato famine, substitute a number of other common household fruits and vegetables, including apples, bananas, or avocados. Instructions for assembly and clock operation are included. --Chris Burns
