So, I don't know that particular video, but I recognize the name unclefester... and I can't recall if he's as bad as the Phrack "cooks" or not. Well, whatever, maybe that works and maybe it doesn't -- as far as I know those materials are no longer possible to obtain legally / unwatched (as in they monitor sales of them very strictly). So it's probably not going to do you a whole lot of good.First of all, I'm certainly not a chemist. I have very little education in the way of chemistry, but amphetamine is one molecule I happen to know a little about; you should still take what I say with a grain of salt though.One of the two easiest/best-known methods is reduction of pseudoephedrine or ephedrine to methamphetamine. This is accomplished by hydrogen iodide, also known as hydroiodic acid. It's a powerful reducing agent that's used in production of various chemicals, but I know fuck all about that industry, so, moving right along. Hyroiodic acid can be generated in the reaction vessel itself by combining red phosphorous, iodine crystals, water, and heating them (heating as in like 100-200 degrees celsius).The hydroiodic acid is combined with red phosphorous. The reason for this is that as the acid reduces the ephedrine molecules to amphetamine molecules, the acid itself is consumed and separates into constituent pieces -- those pieces aren't a powerful reduction agent. By adding the red phosphorous combined with heat and what the acid decomposes into, another chemical reaction is caused and the hydroiodic acid is regenerated and can again reduce ephedrine to amphetamine. So it keeps the process going and helps increase yield (50-75% of the ephedrine ending up as amphetamine is what 50-75% yield means).The entire process is pretty mechanical: you combine the iodine, red phosphorous, and water in your reaction vessel -- which is a glass beaker. Really anything that can take the heat and the strong acid is usable though (like a coffee pot -- get creative). Then you add the heat, and when it looks good, you dump in the ephedrine and fit the container with a condenser, aka reflux condenser. The simplest condenser is a Leibniz (Leipzig?) condenser, which is just a glass tube. They're set up with a chamber that you run water or antifreeze or whatever liquid through.The reason for that is that because you're heating this stuff past the boiling point of H2O, so a lot of stuff starts evaporating into vapor and tries to drift away on its own somewhere. Very rude stuff, that vapor. The condenser and circulating water are at the neck of the beaker so that vapor has to drift through them. As it does, the heat is sucked out of the vapor, which causes it to condense back into drops of liquid that drip back down into the reaction vessel (as if those scum deserve freedom -- hmph!).So you just let this happen for 1-24 hours. It should be watched, especially at larger volumes -- I read that it can get out of hand unexpectedly and very fast, so don't leave it overnight on its own.Then after the cook is all done and you've got your honey (it's often honey colored at this point, hence why meth freebase is called honey), you just need to attach the hydrochloride salt to those amphetamine molecules and then pop those suckers right inside of you. That's just as long a writeup, and I'm not sure I even remember the details properly anymore, so I'm gonna skip it. It's a totally standard process though -- see next paragraph.SO...! What have we all learned today, peoplez?- Well we've learned that generally the process of cooking methamphetamine involves reducing a closely related molecule via a reduction agent such as hydroiodic acid (usually hydrogen iodide is what you call the gaseous form, not the liquid one, but they're the same thing). Ephedrine is such a related molecule.- We learned that a condenser and a steady flow of water are used as cooling agents to prevent our product from drifting away uselessly.- We learned you can use coffee pots instead of high quality borosillicate glass (labware is usually made of borosillicate glass: it's better at withstanding high heat but breaks more easily).- We're now learning that the steps after the cook, as in once you've got your meth freebase and are ready to attach the HCl salt to it (it makes it more stable, otherwise it breaks down or doesn't get absorbed in the body as well upon ingestion), you just follow a process called acid-base extraction followed by titration. Or is it the other way around... well they're like first year chem stuff anyway, very easy to find how-to's online.The actual payoff to this post==================- So why did I bother writing this shit? So that you'd all understand why you don't need a specific "how to cook meth" video. What you NEED is a "redux reaction" video. Not to be confused with redox. Or... whatever the other one is. It's redux, like reduction. - Now you also know what the condenser is for, so look up a video on how to "reflux with a condenser" and you'll get that part taught to you.- So after those two videos are finished, you'd theoretically have your honey. So now you want to look up "acid-base extractions", "titration", and "recrystallization" videos.... and voila!!!! You have meth. Or some disgusting rubbish that nobody's going to want to buy because you fucked it up and didn't actually get any meth out of the whole ordeal. Total failure is common. Yields as low as 20-40% are common. Breaking Bad isn't full of it apparently, I mean 90% yields are extremely rare for clandestine chemists to see. I don't know the theoretical maximum off the top of my head.Oh, some people are selling P2NP on the Road, aren't they. Well that's phenyl-2-nitro-propamine (I think that's right, but w/e) and it used to be a very common precursor for meth production. It's a similar process, but I don't know that one; it also involves an extra step or two to create the meth molecule. It's basically the same thing though, just with an added step or two to convert to amphetamine.You gotta look that up on your own though if you want to learn it.
