For the final part of our Biodiesel explorations, we went back into lab and made biodiesel that we later used in our boats. After making it in the lab one day, we had to let it sit overnight so it could separate, and we could remove the bodiless from the glycerin and glycerol.
Here is what that looked like:
Then, with this fuel we built a small putt putt boat out of an Altoids tin and fueled it in a candle with the fuel we made. Our boat got the third fastest time, and for that we got extra credit!
Here is what our boat looks like:

Holly, your post was very helpful! Before I read this, I did not know what we were actually taking out of the cup of biosiesel the second day, and now I know that it was bodiless. In addition, the two links you posted about making putt putt boats may be very informational for someone making a boat for the first time.
