i'd say it was just as suitable for human consumption as the best sarin from the major superpowers

Cody made a video about extracting the precious metals from catalytic converters and for the video he got a bag of crushed catalytic converter material from eBay and I'm sure that unlike Cody you see what's coming here the seller had already extracted the metals

He apparently wanted to put out the two videos simultaneously and he did have some catalytic converters he took apart himself but I agree that lately he seems to be having some trouble finding good topics for new videos.

So that 10-3 torr...what's going on there? I know torr is a unit of gas pressure, is it saying that the product is 100 C and has to be produced in a near vacuum?

I’m going to guess it has to be done in the dark, because light angers the reagents or reaction products. The makers don’t seem to be the type to be in the business of blowing up spectrometers

For centuries, a rite of passage for chemists was the preparation of tetralitiomethane. This tiny molecule - starting as carbon tetrachloride, force-fed mercury, then suffocated in a near vacuum - was prepared whole and burned that way, bonds and all, while the apparatus was draped with a linen napkin to preserve the precious aromas and, some believe, to hide from God.

Yeah 10^-3 torr is low pressure. It's not hard to achieve on a benchtop with a vacuum pump you could get from Amazon.

10-3 torr is the kind of pressure that you can get if you clean your stuff real good and let a rotary vacuum pump go at it for a while to let everything outgas. It's such a slight pressure that even for the stuff I do with proportional gas radiation detectors which can have their performance fouled by oxygen gas and outgassing crap, I'm pretty happy if I can achieve it with some stability once I turn off the turbomolecular pump (goes down to 10-6 torr or so). I'm not really sure how tetralitiomethane works but I bet you don't want it in the presence of oxygen either.

What brought me to France in the first place was a story I'd heard about François Mitterrand, the former French president, who two years ago had gorged himself on one last orgiastic feast before he'd died. For his last meal, he'd eaten oysters and foie gras and capon—all in copious quantities—the succulent, tender, sweet tastes flooding his parched mouth. And then there was the meal's ultimate course: a small, yellow-throated songbird that was illegal to eat. Rare and seductive, the bird—ortolan—supposedly represented the French soul. And this old man, this ravenous president, had taken it whole—wings, feet, liver, heart. Swallowed it, bones and all. Consumed it beneath a white cloth so that God Himself couldn't witness the barbaric act. I wondered then what a soul might taste like.

Much the same can be said for tetralithiomethane.

Yes, dark, low pressure, 100C temp. The 80% probably refers to the yield. That means that if you do it as described, it is expected that 80% of the original reactant will be turned into the product. If you get way less you hosed up, if you get way more you get to publish a new paper about what you did differently.

It can take quite a while to figure out what you did differently. IIRC polymerisation wasn't figured out until the british and american teams swapped equipment the british gear leaked and let in oxygen which catalysed the reaction, which is why the americans could never get it to work

An American engineer tells a Rolls-Royce guy they can't work to the specified tolerances. Rolls-Royce guy has a smug chuckle before the American tells them his tolerances are so lovely they can't possibly be a guide for mass production. The Brits just employed lots of people to machine the parts down until they fit in one engine or another, meaning essentially every Merlin was custom built, a neat technique but worthless for  mass production with true interchangeability in parts.

Every part on our car engines has to be interchangeable with the same part on any other engine, and hence all parts have to be made with extreme accuracy, far closer than you use. That is the only way we can achieve mass-production.’” https://www.tested.com/art/makers/492418-packard-merlin-how-detroit-mass-produced-britains-hand-built-powerhouse/
