Still making Biodiesel

For the past few days, the students of the Key West High School Alternative Energy Center have been learning how to make biodiesel by making some of it themsevles. Each student brought a 2 liter bottle and followed the process to each make thier own batch of roughly 1 liter of biodiesel. After having made thier own, the students have to clean thier biodiesel using a spray bottle. When the water that has gone through the fuel is completely clear, then entire process is finished.
