Potato Battery Kit or Lemon Battery Kit with 2 Copper Rods, 2 Zinc Rods, Digital Clock, and Wiring

Make a real galvanic battery from potatoes to power a digital clock Zinc and copper electrodes create an electro chemical reaction to generate voltage and converts the chemical energy stored in the metal strips into electrical energy Learn how to wire up a simple circuit. Experiment with different liquids like salt water, fruit juices or fruit like lemon, orange, or tomatos Mini LCD clock with stand to show the time, month & day 2 buttons on the clock adjust the time Environment friendly and lightweight and easy to use Clock size: 66x32x11mm Cup size: 62x51x51mm How it works 1) The metal strips and potatoes make a simple battery that creates electricity to operate the clock. Each potato works as a device called an electrochemical cell. They convert the chemical energy stored in the metal strips into electrical energy . Two potatoes are enough to make electricity to run the clock. 2) Because of the chemical properties of the metals, tiny particles charged with electricity (called ions) move between the two strips of metal. This flow is an electric current.The potato contains moisture that allow the current to flow and keeps the metals from touching. Electric current also flows along the wires between the zinc and copper strips and the clock. This current provides enough voltage to power the clock.
