Okay, so to join us for part two, now that we have our completed oil, is a student from our sustainability and renewable energy systems major. Hello, I'm David Sabaki. And he's going to walk us through the trans-estrification process. So we have some methanol here, methanol, and of course what else do we need? Our catalyst, so our catalyst is methanol and potassium hydroxide. And here we have our oil and what are we going to do? We're going to mix these two together, separate those triglycerides. So take the oil and pour it into here. And then we have to vigorously shake it for about ten minutes. So it looks a little bubbly and the oil hasn't really mixed yet, but once you shake it, you see that immediate reaction happen. And then we're going to shake that for about ten minutes and it's going to result in this mixture here. And then once we let this mixture wait for a while, some people can choose to let it wait for a couple hours or overnight, in our case, we have something that looks a little bit like this. So what we have here, we've got two layers here, that first layer that we have, this is our methyl esters, these are our mix of fatty esters or fatty methyl esters, and it's cold. And right there at that bottom, that slightly darker layer, that is our other product. So what was the other product that we made when we were doing trans-estrification? It was glycerol. So this is the glycerol at the bottom. And when we go to process this biodiesel now, because actually this part right here, is methyl esters, this is what we used to make diesel. This will get filtered out and we'll see in step three, some things that we can do to it to clean it up. And this glycerol will be tapped out of the bottom and then used to go in manufacturing of cosmetics and soaps and a whole other products.
