Gross. What is that in the toilet? But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair project, you will make a microbial fuel cell to collect the electrons that the bacteria in a benthic water sample create - only, you'll be using mud, which is much safer to handle. If you would like to learn how to reuse and recycle an unlikely substance, this is the science fair project for you.
