Fancy yourself as a bit of a scientist? Well, this potato clock kit lets you build a clock powered by two potatoes. Just push the two electrodes that come with the kit into the potatoes, and watch the oxidation reaction produce a low voltage that will power a digital clock. The kit comes with the required digital clock, the electrodes and full instructions, but you'll have to provide the 2 spuds yourself.
