Mumbles Posted May 8, 2006 Share Posted May 8, 2006 Yes, I must say Brainfever is quite the proficient improvisor. He has his nitric acid still too. Link to comment Share on other sites More sharing options...
Rogue Chemist Posted May 8, 2006 Share Posted May 8, 2006 That was my mag stirrer prior to getting a real one. Brainfever's is actually made of metal...not cardboard like mine above. Link to comment Share on other sites More sharing options...
Pyrohawk Posted May 8, 2006 Share Posted May 8, 2006 Hahaha those are some pretty ghetto contraptions there. Although I think I probably could compete for the most redneck pyro here.... Some of the things I've used in the past...and set ups I've done... Well yesterday was interesting.... For starters it was my prom and since I had no date I spent it at work Well after work I decided go to the All Night Party which is just a big after party they throw at the school....and its not really a date thing everyone just kinda goes about with their friends. It was surprisingly fun for how depressed I had been over not going to prom. Plus I won a 50 dollar door prize!! Didn't know where to post this as its not really a good thing but not entirely a bad experience either..... But the party didn't end till late so I got home at 5am. Then had to get back up at 7am to go to work again..... So I'm beat right now!! Just felt like talking. Oh yeah and ya kno those little popper things that look like little tiny bags of rocks but explode weakly when you throw them down. What are they made of? I remember hearing they are just small pieces of rock coated in some sensitive HE I think....but what? Link to comment Share on other sites More sharing options...

Mumbles Posted May 8, 2006 Share Posted May 8, 2006 I wasn't aware there was another homemade stirplate. I could have sworn his was the one with popcicle sticks. Oh well, I can't be totally infallible. Nice work on it none the less, looks very powerful. Link to comment Share on other sites More sharing options...
Swany Posted May 8, 2006 Share Posted May 8, 2006 I'm home dearies. I found some ascorbic acid and some tasty hot sauce. Thus ends my band trip to an undisclosed state. Yes, I am a band geek. Not really, but my girlfriend is a better trumpet player than me. Oh well, I can make dinitroaminophenol and she can't. Is that correct nomenclature? Or is it, aminodinitrophenol, and do I really need to put the numbers? Am I rambing? I'm going to go make some nachos and do my homework. Ugh.... congradulations to the ghetto-millers and the song, very nice, frozentech! I made a ghetto stirrer who somehow did not survive a 5m fall to cement. Curses.

Mumbles Posted May 8, 2006 Share Posted May 8, 2006 Amino would go first, unless you named it aniline, in which case it would be dinitroaniline. Yes, you need to do the numbers technically. I don't know the correct conventions about this, but I think that amino would be the correct place to put one assuming it is 1,3,5 Link to comment Share on other sites More sharing options...
justanotherpyro Posted May 9, 2006 Share Posted May 9, 2006 Ghetto ballmills are the best. All it takes is a little bit of imagination and creativity before you have a ceiling fan propped up with a plastic mayonaise jar glued and taped onto it with bolts and BP chems in it .

d4j0n Posted May 9, 2006 Share Posted May 9, 2006 I feel pampered with my harbor freight ball mill....and my pampered chef cheese grater for wax shavings.... Anyway, who knows of any blue comps that don't use ammonium perchlorate and don't have purple tints? No luck with the pfp database for me...short budget and chem supply, was hoping for some insight from your experiences? Link to comment Share on other sites More sharing options...
dragonman586 Posted May 9, 2006 Share Posted May 9, 2006 Look again. I use the first listed conkling on the blue section. It's easy and it looks pretty good too. Link to comment Share on other sites More sharing options...
Rooster Posted May 9, 2006 Author Share Posted May 9, 2006 Typo there mumbles. DinitroaminoPHENOL is not the same as dinitroaniline. The IUPAC name is (insert number)Amino(insert numbers)dinitrophenol. Alcohols have higher priority than amines, and amino is before dinitro alphabetically.

Schwartzy Posted May 9, 2006 Share Posted May 9, 2006 Alright lets see if I can do this right this time. I was trying to get ammonium nitrate from the instant cold pack method and used a brand that wasn't ACE. Does the cold pack have to be from ACE? The inside package said it contained urea but it was very hygroscopic. And I cannot find anything about urea being hygroscopic. So is it AN or urea? Thanks Link to comment Share on other sites More sharing options...
justanotherpyro Posted May 9, 2006 Share Posted May 9, 2006 It could be a mix. The best ones to buy are the ones that just say " contains Ammonium Nitrate ". At Walmart they are the blue colored ones. Link to comment Share on other sites More sharing options...
ULTRABUF Posted May 10, 2006 Share Posted May 10, 2006 Hey Mumbles, what do the 1,3,5 numbers you're talking about there stand for? Do they represent the position of the nitro group or something? Link to comment Share on other sites More sharing options...
Swany Posted May 10, 2006 Share Posted May 10, 2006 Yes. Google organic nomenclature, it should explain. Aromatic, at that. Link to comment Share on other sites More sharing options...
Rooster Posted May 11, 2006 Author Share Posted May 11, 2006 For example TNT is 2,4,6-trinitrotoluene. You could also have, say 2,3,4-trinitrotoluene, but it is less prone to form because of steric hindrance and the other groups directing force.

PyroJoe Posted May 11, 2006 Share Posted May 11, 2006 Did anybody watch mythbusters tonight? It was a very entertaining episode! They did the "exploding pants" myth. They used 4 different compounds soaked on farming pants. Fertilizer (ammonium nitrate), some pesticide, black powder, and guncotton. One of their guncotton synths went horribly wrong. They probably had at least 2 litres of nitrating solution mixed up. They threw in the sulfuric acid and nitric acid all at once, then jammed a wad of pants in the jar and it was pretty obvious what would happen next! It ran away very fast and was spewing bright red fumes everywhere. That part cracked me up. In the same episode they tested many different interenet inventions/methods for better gas mileage. One was adding a couple ml's of acetone per gallon of gas which actually decreased the mileage by about 7 miles per gallon. None of the methods worked and for the last method they used biodiesel! They went and grabbed a couple litres of used fry grease from a burger joint, filtered it, and poured it into the gas tank without any modifications to the engine. It ran just like regular diesel and they were getting 30 miles per gallon! I've always wanted to make biodiesel and this has made me even more eager to do it. I thought there was some kind of process you had to go through to get the biodiesel, but its just a matter of filtering the grease. I recorded the entire episode and im going to edit commercials and compress it. If anybody has a server ide be willing to upload it for everyone.

dragonman586 Posted May 11, 2006 Share Posted May 11, 2006 You know what I found funny about that episode? When they were doing the intro to the exploding pants myth they zoomed in on a newspaper or computer image and in big font up on the screen it was written Big Bang. relation to bigbang maybe?. Hmmm kinda makes you think that they visit this forum sometimes. Link to comment Share on other sites More sharing options...

Swany Posted May 11, 2006 Share Posted May 11, 2006 Bigbang is mostly harmless, save the stray rocket and hypergolic pants. In retrospect, it may have been dear Bigbang! Owned by the runaway you silly mythbusters! Link to comment Share on other sites More sharing options...
Rogue Chemist Posted May 11, 2006 Share Posted May 11, 2006 Biodiesel is definatly more difficult then just filtering used oil. I have made it a couple times. Link to comment Share on other sites More sharing options...
Mumbles Posted May 11, 2006 Share Posted May 11, 2006 If they visited here maybe they would actually learn some chemistry. They may also learn that Mumbles > Them. Yes, biodiesel is definatly different from filtering oil. Though you can probably run an engine off of oil, though it may require some modifications. It would certainly be cheaper. Essentially bio diesel is an alkyl ester of some of the acids. You react the oil, MeOH(usually), and NaOH or KOH.

BigBang Posted May 11, 2006 Share Posted May 11, 2006 It is episodes like this which makes me truely wish I had cable. Oh well, they'll re-run it a few hundred times over the weekend so I might catch it. Calling me haremless ehh? Just know that when you eat lettuce, it might just be treating yourself to a heaping helping of NH4ClO4. With all other the rockets the club and I fly, on a lettuce farm at that, there must be some contamination. Its been tested and trace amounts have been found Biodiesel does look interesting. I've heard that the exhaust smells like whatever the grease was used to cook. Drive down the road smell like frech fries, how nice Link to comment Share on other sites More sharing options...
ewest Posted May 11, 2006 Share Posted May 11, 2006 Those ghetto ball mills could easily be converted into star rollers also you know. Take another fan and hot glue a Tupperware bowl on it and voila! ok, I'm hitting some garage sales this weekend I guess LOL Link to comment Share on other sites More sharing options...
