What do you do with a boiled potato?

What do you do with a boiled potato? You slice it, insert it between two electrodes, place an alligator chip, and turn it into a battery. The device has been used to provide LED-powered lighting for 40 days (and at a fraction of the cost of a typical AA battery). The potato battery kit could be used in remote regions and, because spuds are starchy and rich in phosphoric acid, they will last for several months and won’t attract insects.
