This clock is powered entirely by dirt. I'm clueless to how this works.This exciting project provides all materials necessary to create a mud clock. No batteries are required to power this digital clock using dirt from your own backyard. Plant your favorite flowers in the included pots and attach the clock components. Soon after, the time is accurately displayed without the need for additional power sources. Experiment with what substances will power the clock - do tulips or lillies work better?
It is selling at $19.95.
