Draco_Aster Posted August 1, 2008 Share Posted August 1, 2008 Haha, nah i know that, I started the alcohol thread, how ironic. Its just that when I'm 18 I will have the need for copious amount of beer...free of taxation! Hopefully when I get my car shmick there will be more time for the new 30L still and rockets.

All, here is A WELL WRITTEN article on the state of chemicals, chemistry, and home labs... this is a very good read, check it out.

BigBang Posted August 2, 2008 Share Posted August 2, 2008 Hey I mentioned last year that I picked up a crap load of uranyl acetate from a friend. Now I'm broke and need cash (go figure, geting ready for college.) I figured I'd like to sell most of it because, come on, what can I do with (i think) 6 pounds of this stuff except be irradiated. I contacted United Nuclear and they said they would pick it up for less than $300/pound. I check it out online and see it being sold for $2000/pound. Sure I know they need to make a profit but I need to pay rent and stuffs. Anyone here know who might buy it for, say $500-$1000/pound? Heck, would anyone here (or maybe science maddness if you fellows would pass the word) would want to pick any of this up? Link to comment Share on other sites More sharing options...
Richtee Posted August 2, 2008 Share Posted August 2, 2008 Hey I mentioned last year that I picked up a crap load of uranyl acetate Hey keep yer urine up yer own ass-atate eh? LOL.

WarezWally Posted August 2, 2008 Share Posted August 2, 2008 UN's offer is pretty good, its going to be hard to find another buyer. I'm tempted to buy a few grams of uranyl nitrate merely for collection purposes. btw, drunk again Link to comment Share on other sites More sharing options...

All, here is A WELL WRITTEN article on the state of chemicals, chemistry, and home labs... this is a very good read, check it out. Yeah... If you bought the print edition of that article ( well, actually, the following month), they printed my letter to the editors about the situation. Took me by surprise, I had emailed in a long comment about it, then I got an email back a few days later, asking if they could print it. If I had known, I wouldn't have ranted as much LOL.

Well try to negotiate we all know UN sells at outrageously high prices tell them you know people are selling it for much much more then they are offering you maybe you can squeeze more money out of them.

flying fish Posted August 2, 2008 Share Posted August 2, 2008 (edited) I was riding my bicycle on one of the nearby trails today (old railways that have been torn up and re-finished for people to run/walk/bike on), and I picked up a small downed branch from a willow tree on my way back home. People were looking at me funny, with me riding along holding a branch...I can just imagine them thinking "aren't you a little too old to be collecting sticks?" Or more likely just "what the hell?" Or possibly "Don't whack me with that branch!" I always tend to get into situations like that...Like when I was working in Ann Arbor, I picked up some fire bricks for an experiment at one of the local art places. On my way back to my car people were looking at me funny and one kid shouted "BRICKS!!!" Edited August 2, 2008 by flying fish Link to comment Share on other sites More sharing options...
asilentbob Posted August 2, 2008 Share Posted August 2, 2008 Speaking of UN they are moving to MI or something where alot of people who worked at car factories recently lost their job. UN is really trying to push their partial hydrogen conversion so they are going to try to hire several people who worked in the factories to help them get things going smoothly enough to start offering kits. I'm sure they will be quite expensive what with the price of the metal hydride storage medium. There are some metal hydride alloys that can absorb hydrogen at 25C and 1atm well, then release it around 100C creating significant pressure. The computer modifications would be complex and not DIYer friendly I think... but otherwise heating up the hydride bed with waste heat from the exhaust or with heaters should be a simple modification. I actually was reading up a bit on hydrides last night and it got me thinking about the possibility of making NaK liquid eutectic alloy (MP -12.6-785C)... Then adding small amounts of other metals to it like Al, Zr, Ti, Pd, Ni, Li, etc to form a hopefully still liquid alloy... probably with some non-alloyed things floating around... THEN bubble hydrogen into it at near room temp... It should hopefully form solid hydrides and end up with a porus solid mixed metal hydride mass... Doing everything under inert gas of course. Then you could put the hydrides into whatever heat resistant plastic or fiberglass storage tank and heat it to release H2... Then recharge it again with leading dry hydrogen into it... The problem is... that that would be a whole lot of metal hydride to store any useful amount of hydrogen. What can be done with hydrides is pretty amazing.

flying fish Posted August 2, 2008 Share Posted August 2, 2008 (edited) United Nuclear hiring 100's of people? I always had the impression that UN was a very small organization....Like a handfull of people working out of their garages. Then again, I also had the Impression that Mumbles was a really old guy before he told me he was a standard college age student. That is interesting though. I do live in the "motor city" area...luckily I don't work for the automotives nor do I ever plan to. Edit: Have something semi-interesting to share. I made some small split comets (5/8") by the following method (unfortunately did not get them on video): I used my very simple homemade tooling which pumps cavity stars - very simply a 5/8" dowel with a brass rod friction-fit into a hole which was drilled into it...and then brass tubing that the dowel would fit into after a little sanding. After having some charcoal comets made with this tooling, I cut end disks for the comet from a corn starch box (any cerial box of other source of non-corrugated cardboard should serve the same purpose). One end disk had a 1/2" length of American visco fuse inserted through it, and glued with Titebond woodglue. The same woodglue was used to attach the end disk opposite of the fuse side. This was to insure that the comet did not burn through into the break charge, causing early ignition and/or jetting. Next, the cavity was filled with 70/30 for the break charge, and the end disk with the fuse was glued on with the woodglue. After this dried, some hotglue was used to seal around the base of the fuse. The result of this was split comets that functioned beautifully! They broke into fairly symettrical pieces...maybe about 5 or 6 pieces each. I shot them out of 3/4" mortars with 1.25 grams of FFFG, and they broke pretty quickly...I could probably make the delay longer than 1/2"...I might try 5/8" next time, though I kind of liked the effect of the star breaking while it was still going up so maybe I won't! In any case a cake full of these split comets would be quite pleasing I believe. Another interesting point that this causes me to consider is that perhaps I'm not far off from functional crossettes with homemade tooling. Perhaps all I would need is to find 4 rods and friction fit them in a + pattern into my ramming dowel. Sorry for the long drawn out post, but I'm kind of excited about how beautifully these functioned. Edited August 3, 2008 by flying fish Link to comment Share on other sites More sharing options...
Mumbles Posted August 3, 2008 Share Posted August 3, 2008 I actually get that a lot from people who do not know me as well on a personal level, just from forums and such. I think it's kind of funny. With people I know on a more personal level, I am not very serious with at all. I guess on the forum the work side of me comes out. When people started putting 2 and 2 together with my name from Passfire or rec.pyro and the WPAG, I had at least a dozen people ask me if that was me, and then a few didn't believe me.

XinE895 Posted August 3, 2008 Share Posted August 3, 2008 haha Mumbles... wait so your not an old guy? never mind... I already know the answer... its pretty amazing the things you know considering your age. On a more personal note, check out this awesome picture of me... I had to hand light my show this year, I didn't dip my ignitiors in anything to waterproof so the humidity got to them, but I had a buddy helping me so it worked pretty well, and my girlfriend who had my camera was taking pictures, it makes me happy I'm not gonna lie. Good shot of me in action...a lot of smoke but still a really neat picture. Here is a couple more pics because I feel like sharing... Link to comment Share on other sites More sharing options...
mormanman Posted August 4, 2008 Share Posted August 4, 2008 Swede you missed out man. Here is a taste of how it was.My friend with the 50 cal. I shot it twice for $10 and well worth it. http://i34.tinypic.com/2j35moi.jpg50 cal vs propane tank aftermath. http://i35.tinypic.com/1ze8nco.jpg The videos are still being processed but will be up soon.And sorry guys I meant to take a video of the 4in shell of shells. But it was perfect. It was surprising. I watched it go up and the break was perfect with a perfect hight and the boom the break. Then I saw the other shells and while I watched it go up I forgot everything but the size. Don't worry I'm making more. Link to comment Share on other sites More sharing options...

BPinthemorning Posted August 4, 2008 Share Posted August 4, 2008 2 things:1. http://www.pyroauction.com/auction/index.php Its like a pyro ebay... Just want to see more traffic on it. Its not mine, so ya...2. Just want to say that I bought some of the chemicals listed in the agora from Dystrophy. And I got everything. very good to do business with him.

mormanman Posted August 6, 2008 Share Posted August 6, 2008 I'm looking for a green star comp that uses zinc needle or anything green that uses zinc needle. I'm not asking to search for me unless you want to but if you know one off the top of your head I would greatly appreciate it if you would share it.Thanks Link to comment Share on other sites More sharing options...
Mumbles Posted August 6, 2008 Share Posted August 6, 2008 A mesh size might be helpful. However any comp that uses metallic zinc could probably also use "zinc needle", even though I have never heard of it. Link to comment Share on other sites More sharing options...
mormanman Posted August 6, 2008 Share Posted August 6, 2008 Well I don't think that there is a mesh size. I found some zinc wire and started cutting it up into small bits and it look similar to Ti needle so I just called it zinc needle. Link to comment Share on other sites More sharing options...
flying fish Posted August 6, 2008 Share Posted August 6, 2008 Well it might be arguable that everything has a mesh size, as it is simply a unit of measure. Marbles would pass a 1 mesh screen and perhaps you could screen in elephants through a .0001 mesh screen, if you could find materials to undertake such an operation . I believe window screen are in the 10-15 mesh range... or something like that. Sounds like it is pretty course material though if it was made by cutting up a wire...so it might be difficult to use as a fuel in pyrotechnic compositions. Unless you plan to use it as a coarse spark generator in the same fashion that firefly aluminum or Titanium are used (which may or may not work). Probably not useful for zinc greens...but at the same time I haven't tried it...so it wouldn't hurt to experiment and hopefully learn something!

qwezxc12 Posted August 7, 2008 Share Posted August 7, 2008 (edited) ...perhaps you could screen in elephants through a .0001 mesh screen, if you could find materials to undertake such an operation Not that this helps the actual pyro conversation, but a .0001 mesh screen would have holes 10,000" (833.3ft.) square, far too large for screening elephants...you could end up with Blue Whale, Yankee Stadium and apartment building contamination in your mix... For screening and separating elephants, I'd recommend a .006 mesh type 316 (marine grade) SS screen. Don't use brass screen as it may corrode.

crazyboy25 Posted August 7, 2008 Share Posted August 7, 2008 Your zinc is far to coarse to work just like you can't cut up copper pipes and use it for blue comps or use aluminum foil in glitters. Link to comment Share on other sites More sharing options...
