Does anyone know the significance of nitrobenzen, the compound indicated? Per Wikipedia " The production of nitrobenzene is one of the most dangerous processes conducted in the chemical industry because of the exothermicity of the reaction (ΔH = −117 kJ/mol)" but I wonder if there's something else too.

: It's almost certainly the exothermic (read: potentially explosive) reaction that he's going for. [[Special:Contributions/172.70.110.207|172.70.110.207]] 20:11, 20 July 2022 (UTC)

: It is also the formula of Niacin, one of the B vitamins (same atoms, different arrangement)  Possibly this is the point: the molecular formula is ambiguous, there are several well-known chemicals with this formula, with very different properties [[User:Zeimusu|Zeimusu]] ([[User talk:Zeimusu|talk]]) 20:58, 20 July 2022 (UTC)

I wouldn't know which way to put this, but "make your own molecules" could be parodying the "build your own PC from bits", "compile your own OS distro", "actually cook food from raw ingredients, not packets" or various other supply/consumer things that some people (those who know enough about what they're doing) will actually do, many people (who don't care to know) won't even consider and some (with a little bit of knowledge, but not actually enough) might find the revelation that they ''could'' do some things themselves far more compelling than the valid question of whether they ''should'' just leap in and try to do it (making all kinds of mistakes/reinventing various wheels along the way) without further research.

:There are also a lot of make-your-own-film-developer nerds, which is a little bit closer in that you're using household items to try to recreate the reactions created by otherwise expensive chemicals. [[Special:Contributions/172.70.130.217|172.70.130.217]] 22:37, 20 July 2022 (UTC)
::I never even heard of those. I used to live in a household where there was darkroom equipment, even, so know a little of the process of doing that (more so than academic chemistry lessons) but I'd shy away from trying to substitute like that. If it's a thing, then might be worth linking (when and by who it can be). [[Special:Contributions/172.70.162.155|172.70.162.155]] 10:33, 21 July 2022 (UTC)
:Megan could also be so used to using "free and open source" software, where you can download the source code, make some minor modifications for your situation, then compile it and use the executable.  Here the source code is easy to get but the compiling process can be much more challenging. [[User:Nutster|Nutster]] ([[User talk:Nutster|talk]]) 16:34, 24 July 2022 (UTC)
: Equally could be parodying fallacious thinking in corporate procurement that says 'if we build system x in-house, we won't have have to pay some supplier loads of money to do it', which ignores that the supplier is likely leveraging economies of scale by developing for multiple clients, and ignores the costs of supporting and maintaining the system.

:::: It seems to be typical 4chan terminology. Someone who spent some time being influenced there, or maybe one step removed in their own little chan-wannabe dark cave sitting in some other area of the twilight internet taking most of their prompts from the 'real rebels' who are probably just egging them on for their own meta-amusement, but that the stooge(s) would know it. And the repetitious interleving of vandalism modes employed (which are fairly discernible as different until you find the same source has done two or more of the things at once, unifying their identity) indicate a singular whim, if not a singular actor to perform them, who gradually has added new variations to the repertoir of damage to try to be 'clever'. If anything, it just shows how limited they are. [[Special:Contributions/172.70.162.155|172.70.162.155]] 10:33, 21 July 2022 (UTC)

<s>I wonder if we should mention the economic difference between small quantities of chemicals typically used in laboratory experiments compared to bulk quantities for industrial manufacturing. The latter often ''is'' cost-effective to do in-house, and the current version of the explanation doesn't make that clear at all. We have no idea if Megan and Cueball work in a lab or a factory!

I wonder if this could be referencing the video game Spacechem? The premise is exactly this, of chemical engineering using individual atoms to form desired chemicals, and it's the type of nerdy game Randall might enjoy - or at least have heard of. -- [[Special:Contributions/162.158.162.113|162.158.162.113]] 09:54, 21 July 2022 (UTC)

SpaceChem was the first thing I thought of reading the comic.

I removed "Similar to the makerspace movement, community chemical labs have been cropping up, where people work together to perform chemical synthesis and other chemistry acts by sharing community resources," because it doesn't seem to be true; see [https://peer.asee.org/the-design-and-impact-of-a-combined-makerspace-wet-lab-and-instructional-design-studio-for-chemical-engineering-curriculum.pdf]. Maybe someone can think of something similar but less misleading from that paper? [[Special:Contributions/172.69.33.123|172.69.33.123]] 11:52, 22 July 2022 (UTC)
: I actually was a very fringe part of a group synthesizing coronavirus tests at a community lab, and have elesewhere participated in groups with community labs. I have some neurological issues and have not yet found a citation or reviewed your reference, but the statement is indeed very true.

:: There is a reason that we as a society house exploratory chemistry labs inside high schools, colleges and universities, but we allow co-ops and makerspaces to host mechanical and manufacturing tools. It's mostly the greater extent of safety equipment, protocols, supervision, and training compared to hand tools and shop equipment, but also the huge regulatory burden of storing thousands of precursor chemicals, many hundreds of which are likely to be deadly poisons, explosive, radioactive, drugs of abuse, potent carcinogens and teratogens, or just absurdly expensive. Have a look at [https://www.youtube.com/watch?v=oIHxPc7EpP8 this video] to get an idea of what a modern synthesis lab is like.

: From your link: "In this work I describe the design and impacts of a makerspace at the University of Utah, created specifically for chemical engineering curriculum." -- is your concern the phrasing around "cropping up", that the statement implies more labs here than your experience is that there actually are?

:: If you read about what they actually use the makerspaces for, it's mostly glasswork and manufacturing of lab equipment, not synthesis at all. [[Special:Contributions/172.69.33.177|172.69.33.177]] 14:07, 22 July 2022 (UTC)

:: It looks like they closed their public access to the chem lab in 2018 when they became Librecycle.

You could take the "savings" one step further:  Instead of buying dozens of different atoms, just buy a bunch of protons, neutrons, and electrons!  Only 3 particle types needed!  You may need to work out some minor issues with packaging and transport, however. [[Special:Contributions/172.70.126.49|172.70.126.49]] 21:13, 22 July 2022 (UTC)
