Have you ever started doing your math homework with a calculator and then suddenly the calculator stopped working? What would happen if this happended and you couldn't find any batteries? Are there any items in your refrigerator or pantry that you can use as a battery?

In this experiment we will test different types of vegetables and fruit to see if we can use them to power our calculator. What do you think - well except that we are crazy of course. Do you think we can use potatos, oranges and/or lemons to power our calculator? Vote below. Once we get 50 votes we will do the experiment. THANK YOU!!!!
