With the Novel DIY Green Science Potato Digital Clock Timepiece you can make a real galvanic battery from potatoes to power a digital clock. Zinc and copper electrodes create an electrochemical reaction to generate voltage. The metal strips and potato make a simple battery that creates electricity to operate to operate the clock. Each potato works as a device called a electrochemical cell. It converts the chemical energy stored in the metal strips intoelectrucal energy. Two potatoes are needed to make electricity strong enough to run the clock. It has a mini LCD clock with stand to show the time, month & day, with 2 buttons on the clock to adjust the time. It is
environment friendly, lightweight and easy to use.
