Speaking of chemistry, if I order a bottle of dichloromethane to clean PLA off of 3D printer heads after ... incidents ... it looks like I should use vinyl gloves and do it in a fume hood, is that sufficient? edit: with goggles, of course.

I would search up any and all instructions instead of what some jackasses on an internet forum will say. Especially since how careful you need to be depends on how you're using it.

If they're all-metal heads, I just torch PLA out. ABS tends to turn black and carbonize even with the heat of a MAPP-Pro (not MAPP, that was discontinued in 2008  ) torch, but PLA seems to burn cleanly away.

I want to drink with that dude. "So this one time we made Cyclosarin just for shits and grins. The MoD confiscated the entire laboratory but we kept some in a spray bottle that we've misplaced. Oh well, by now it'd likely be only about as deadly as Soman."

Intoluene posted:I'd probably avoid DCM if at all possible without proper lab conditions. You mean like the fume hood he mentioned? The quantities GWBBQ will be using are miniscule and a fume hood should be fine. I used to add ~40 gallons a week to our degreaser to make up for evaporative losses going up the exhaust system. Well, mostly going up the exhaust system: it will be extremely obvious if the fume hood isn't up to the task because there's no mistaking that icy-hot feeling when you catch a good whiff.

Arglebargle III posted:Try not to work alone with any solvent that could theoretically overpower you. One day at college, we were waiting on one of our friends to finish his o.chem lab so we could go to a party. We waited until he was an hour overdue, then went to the lab to retrieve him. Upon opening the door, visible shimmer lines came out and the smell of ether was powerful. Through the shimmer and haze, we could see our friend slowly working on something. "DUDE," we yelled, "GET THE HELL OUT OF THERE! ETHER!" "no..... guys...... i..... just..... need..... to...... finish..... this..... real..... quick....." He was talking and moving in cartoonishly slow motion. Someone familiar with the o.chem lab ran to the 35l bottle of ether, put the top back on, then turned all the fume hoods on as he grabbed our friend on his way out the door. We dragged him, slowly protesting, to the party. About twenty minutes later, he's got a raging headache and asked us what he was doing, where he was, and had he finished his lab? We explained what happened and he thanked us profusely for not letting him die in the o.chem lab.

In my university it was completely against the rules to be in a chemistry research wing on your own. Working late was allowed but only if someone else also stayed around.

Oxygen makes things burn, ClF3 ... is like the morphine to O2's aspirin, if I may make an analogy. Or the sea to the pond, whatever. Is there a material that is oxidixed at STP Earth atmosphere that compares to ClF3 but from the other side? Guess I answered my own question there, but not energy-wise. That poo poo was briefly considered for rocket fuel, ClF3 BURNS ASBESTOS. AND WATER. AND SAND. AND YOU. AND STEEL IS RIGHT OUT. AND BASICALLY ANYTHING YOU CONSIDER ALREADY BURNT TO ALL HELL THAT poo poo STARTS A ROARING INFERNO WITH Like a magnesium fire will get hot enough to split the water, but a metal-halogen fire is just "stand back and watch it burn" and ClF3 has two halogens very shakily holding hands at the ball. Not sure what analogy I'm getting at, but ... There's a boom in there somewhere. Chillbro Baggins has a new favorite as of 05:57 on Feb 21, 2018 |

A lot of what clogs the 3D printer nozzles isn't the ABS itself, but dyes and other not-plastic contaminants that are in the filament itself that get stuck in the nozzle innards.

Altered Carbon was good and fun even if it didn't live up to the grandiose dreams of people who read the book and wanted an exact remake in a new medium, regardless of how well certain bits would translate.

Lol, “wanted an exact remake”. I’m cool with adaptations, but not when they go all opposite-day on some of the foundational elements of the books. That being said, it’s a good show and you should watch it. There was some very cool stuff they did story-wise that wasn’t in the books. Personally I felt it fell short of greatness due to being completely tone-deaf to novel. But hey, go read the TVIV thread if you’re interested in pointless wankery over it. Including the dumbest debate of existential dread in history.

I think a Consider Phlebas adaptation would have a lot of grotesque and horrible stuff in it and not be very representative of the books or get at what makes people like the setting. So they'll definitely do it.
