No, it's not just that they're the same price, there's not a lot on offer in the first place. I'd expected at least one seller to have inks at varying sizes, but it's usually just a small bottle.

Maybe it's one of those products that it's just not worth it to sell by the piece.

I bought a ton of board stickers for a project. I can't use all of them. Anyone want a random envelope of a dozen stickers? Send me a PM. And let me know if you're okay with NSFW stickers, as those are the ones I can't use.

If it turns out to be tritium rods, would this be the first instance of gaslighting about gas lights? Unrelated: I am becoming increasingly peeved at how many times the suggested other items after completing a purchase, turns out to be a cheaper version of what you just bought. And by how many times I mean every single time.

Tritium is an isotope of hydrogen. You can't get a "rod of tritium" unless you've got some way of storing things at less than 14 kelvin. The radioactive boy scout made his reactor with thoriated lantern mantles and the americium from smoke detectors, iirc, both of which you can still buy

Sagebrush posted:Tritium is an isotope of hydrogen. You can't get a "rod of tritium" unless you've got some way of storing things at less than 14 kelvin. I see. I was referring to an article about him. In it, the reporter tells of him buying tritium-illuminated gun sights and, "digging out the waxy material for his reactor." He would then send the sights back to the manufacturer to be repaired, where he would then do the same thing again. "Once again, "Professor Hahn" sprang into action, writing his old friend Erb at the NRC to discuss the problem. The NRC had the answer. David's neutrons were too "fast" for the uranium).(3) He would have to slow them down using a filter of water, deuterium, or tritium. Water would have sufficed, but David likes a challenge. Consulting his list of commercially available radioactive sources, he discovered that tritium, a radioactive material used to boost the power of nuclear weapons, is found in glow-in-the-dark gun and bow sights, which David promptly bought from sporting-goods stores and mail-order catalogues. He removed the tritium contained in a waxy substance inside the sights, and then, using a variety of pseudonyms, returned the sights to the store or manufacturer for repair--each time collecting another tiny quantity of tritium. When he had enough, David smeared the waxy substance over the beryllium strip and targeted the gun at uranium powder. He carefully monitored the results with his Geiger counter over several weeks, and it appeared that the powder was growing more radioactive by the day." By the sounds of it, the material has never really been workable in the way it's described in the story.

Tritium gun sights are little glass vials filled with a phosphorescent liquid. A miniscule amount of tritium gas is dissolved into the liquid, and its beta decay keeps the phosphors constantly glowing. I suppose the vial contents could be the "waxy substance" they're talking about. Personally I doubt that the tritium would stick around very long once you'd broken the vial (how long does it take for soda to go flat once opened, for instance?), but I don't know the exact chemistry of the stuff so maybe it could work.

He would then send the sights back to the manufacturer to be repaired, where he would then do the same thing again. Hahn was an idiot and very little of the stuff he did was workable aside from putting himself and possibly other people in danger. I would be surprised if he didn't just lose all the tritium as soon as he cracked the sight open. Hydrogen is a gas, not a "waxy substance". No one who actually knew anything about the subject would even entertain the idea of collecting tritium for use as a moderator either. Maybe someone who built a fusor and wanted to be more hardcore by using a D-T mix, maybe, but there isn't much you can do with it for the dumbass poo poo he was trying to do. edit: if there really was some kind of wax inside the sights then it would act as a moderator all by itself because wax is a hydrogenous material but I'm skeptical that a thin smearing of the stuff would moderate the neutrons sufficiently anyway edit 2: if the guy really did come up with such a convoluted scheme just to get a thin layer of wax then loving lol when he could have just bought candles or something BattleMaster fucked around with this message at 20:09 on Jul 18, 2017 |

I've never seen one that's liquid-filled and can't find references to any; tritium's such a weak emitter it couldn't penetrate liquid, or wax, or anything. All the ones I've handled are just a little vial of gas lined with radiofluourescent powder, probably zinc sulfide idk. Maybe he scraped that poo poo off the sides thinking it was the tritium, which wouldn't surprise me since the 'backyard nuclear reactor' was never more than a pile of salvaged radioactive crap, equally likely the reporter's a moron.

I assume that information about Hahn's "experiments" is distorted by writers who don't know anything about the subject, but also that he was an idiot and didn't know what he was doing in the first place.

I can't remember where I heard that about sights using a phosphorescent liquid, but here's a page from Idaho State University referring to liquid-filled gun sights. It looks pretty old so maybe it was an older technology: quote:Gun Sights http://www.physics.isu.edu/radinf/tritium.htm Either way, if the guy was interacting with a waxy substance it was undoubtedly mostly wax, not tritium.

That seems like a great way to hurt yourself and a bunch of bystanders and cause a ton of collateral damage on top of the usual EDC idiocy of making it harder to argue self-defense. And that's assuming that the thing actually works perfectly instead of just leaking and exploding or failing to actually light when you whip it out.

All this talk about tritium got me thinking about making a poly carbonate ring with a bunch of those little(1.5mm x 6mm) tritium vials embedded in it. When it's finished, the little glowing tubes will be fully encapsulated inside the clear ring, thus giving me a sort of ever present light source that is powered by scary radioactivity. I'll let you all know if my hand grows a second, smaller and bloodthirsty mutant hand. I bought 8 of these little fuckers... https://www.aliexpress.com/item/EDC...89-4c8a3f7058fa

blugu64 posted:So can I order those tritium key rings from aliexpress, or will that land me in federal prison? (In the USA) I had a blue one of those a while ago and although it always glowed, it is much dimmer than you might expect: i.e. in a totally dark room you can read a single line to text from a book about the same length as the keyring. If you dropped it on the floor, you could probably only see it if it were a pitch-black night, not at dusk. OTOH: https://www.amazon.co.uk/McNett-Nitestik-Glowing-Key-Ring-x/dp/B005W0NAZA/ref=pd_sim_201_2 these ones need to be charged by a bright light, but do last a few hours and are much brighter.
