On Friday, we found our biodiesel separated into three layers! The top and bottom layers were impurities, and our actual biodiesel was the middle layer. To test if our biodiesel worked, we filled an empty tea light wick with the biodiesel and lit it. Sure enough, the flame was sustained for quite a bit, indicating that our biodiesel worked great!
Too bad your biodiesel died. Good job though on getting 3 layers. That means you did a good job of cooking the biodiesel! I kinda wished we could have used our own biodiesel in the end.
