    Factoid: The soil is not powering the clock: the two electrodes are – the soil is acting as an electrolyte.
    This is the same situation with lemon-powered and potato-powered clocks.
    You might remember the phrases “Potential Difference” from school – well between any two metals there is a difference in their properties which allows a current to be drawn.
    Please feel free to bore your friends with these exciting facts!

  2. Thanks for setting us design junkies straight!

  3. Not boring at all – fascinating! And I DO remember something about potato radios!

  4. You could say the same thing about a battery. The electrolyte and electrodes together make up a battery. Neither does anything by itself as far as powering anything.

  5. This clock is great. A true scientific experiment. This is a must gift for someone.
