I thought that the project was gonna be fun but it would be hard! After we researched about biodiesel it seemed a lot easier, because we had more information about it. I am wondering how long does vegetable oil last in a school bus. The project is that our class has to create biodiesel that is safe for a school bus to run on. This is going to be a project over a 5 week period. I think this project is going to be awesome!
