So for our science fair project, me and Keri are using the whole potato battery thing for our basis. The only thing is that, I can not get it to work. If anyone knows how to make one work, I'd really appreciate the help. Science fair is this Friday, and we haven't even started on our project. Well actually, I've been trying to make it work the past three days, but no luck. So yeah, right now I'll really freaking out and I don't want to fail.
