Science Buddies: "Ask an Expert"

I set up my Keego Microbial Fuel Cell and I used sweet peet. I just read that I was not supposed to. What should I do now? Can I remove the dirt and use the right topsoil or will the MFC not still work. If it's going to take longer with sweet peet then I've got a problem. This has to be done by the first week of December.

I looked on the Keego tech site and the MFCs are reusable. I will just start over with the right type of topsoil!
