Yes! It is possible to make a /very/ small battery using a potato. (You can also do this using a lemon.) You can find the details on how to do it and why it works under the "Electricity and Magnets: Circuits" section of our answers list. The one thing that that answer doesn’t point out is that if you can’t get the bulb to light with only one potato, you should try using several. You may need as many as 4 potatoes to light a single bulb because they put out such a small amount of electricity.
