I made biodiesel. I used methanol, lye, some sort of vegetable oil, 2 bottles, a glass jar, a funnel, a spoon and a blender/plastic bottle. I worked with my dad at home and my plans didn't change throughout the project. If I were to do this again, I would use all types of oils and use a blender. This was a fun and easy science project over the weekend. It is also a cheap and simple way to save money.
Step 1: Step: Materials
methanol 200mL (ex: heet),
lye (3-5 grams),
type of used vegetable oil (ex: waste vegetable oil or peanut oil),
2 1.5-2 liter bottle,
and an old blender or bottle (do not use after methanol and lye are blended inside blender.)
