A few months back I tried my luck at a potato powered LED but I never got the LED to light up. Tonight with the help of another "science toy" we built a potato powered clock. The product is from the same company that I built the Dynamo Torch from. Its n from the company ToySmith, and its their 4M Green Science projects. I have found the products locally, but I think I need to start getting them on Amazon because they are a lot cheaper.
