To demonstrate the principle electrochemical cells. This digital clock runs on potatoes, oranges, plants, soda etc. The acid in the material reacts with the electrodes to produce low voltage current. You can experiment with different items to observe what happens. Color of the body may vary.
Clock that runs on two lemons instead of batteries.
The electrodes are made of different materials and together with the citric acid from the lemon, they generate a small voltage that is enough to make the clock work.
Clean the electrodes well after each use, otherwise the clock will work less and less.
Supplied without lemons
