What it is:
A complete science kit for discovering how to power a digital clock using mud.
Why we love it:
Teach your garden to tell time! 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? This kit was designed at Middlesex University - one of the leading universities in the UK. Contains digital clock with leads, flower pots, copper and zinc strips, screw driver, wire, connecting blocks, and detailed instructions.
