The Potato Clock reminds me of a fun grade school science project. A simple contraption, it brings a unique way to tell time in the comfort of your own home (or laboratory, which ever you would like to think of it now).
Brought to you by Toysmith, the Potato Clock two sets of wires and conductors that harness energy from two separate potatoes, which then power a digital clock. Priced at an affordable $11.08, it is available online at Amazon. Of course, the potatoes are not included.
