How to make Glycerine (Glycerol)

This video was requested by a commenter...I don't remember who, but this video is for you! I went with the method of producing biodiesel, but you could also go with simple saponification (different procedure though).
The process is very slow and long. It is much easier to simply buy glycerol from the store. It would be much faster and much more pure than making it yourself.
Glycerine can be made from triglycerides in vegetable oils. Most bio-fats are stored as triglycerides which are made of 3 fatty acids and a glycerol backbone. This is the same method as making biodiesel from vegetable oil. where glycerine is normally considered a by-product.
