Fruit and vegetables like bananas are able to conduct electricity, due to being ionic conductors. Ionic conductors are objects that contain both positive and negative charges. In hopes of saving money on this project, we decided to try to find an object that we already had lying around, so we went with a banana. I would say using a banana is a pretty unconventional way of using electricity. With our banana, we stuck the positive part of the circuit into the meat of the banana, while we stuck the other end just in the peel, via the stem. Once powered on, the LED lit up due to the electronic currents traveling through the banana.
