In doing my research on this project I found that a potato that has the right elements can produce a small electrical charge. I attempted to look at different chemical reactions from different metals could produce enough energy to turn on a plain low voltage calculator. as a result of testing this project I was successful. The project worked. The following websites were very helpful in explaining and assisting me in my project.
