Nice lol! Here's something interesting. A chem professor at my university published a research paper entitled, "Crystal lattice effects on orientation and orbital degeneracy of nitric oxide trapped in nitrame stage 4 crystals"
The nitramines he used were RDX and HNIW :)

PRRT: Nice.
Tzar was telling me last night about some sexy e-matches she made with acetone, DBSP, and graphite. The idea is not new. I just wonder if any particular brand of DBSP has enough graphite to make perfectly resistive heads without need for additives... Such would be awesome for DIY mass production... And they would be much more stable than normal commercial e-matches that are generally based on some sort of chlorate composition.. some you can practically strike like matches, course they will just pop like normal...
Posted from mah cell...
(On second thought... I don't see NG as having a place in e-matches...)

Heh, PRRT. I used to be a regular at BB, but then I moved on to real chemistry :p. I jest, of course, but one concern that was voiced a while back was that the science of BB seems to be at a stall. As a more flashy science (lol @ my pun), it tends to draw a lot of n0oBz. I think it might be worth collectively figuring out how to deal with them so to turn them from the dark side. Clandestine science could use a boost, and BB is a great way to draw some new people in. IDK, but with more people involved in such a cool hobby, maybe we can sway public opinion to not view science as boring.
Hey, and as to future of BB stuff, FAE's seem pretty cool, and they seem pretty OTC, which is the main criterion for most people. Anywho, there's that.

I find that proposition vaugely disturbing to be honest man! I rather like the idea of people coming in of their own volition, starting with pyro, preferably moving onto HE, then preferably branching to what area they should so desire, drawing in a larger and larger userbase tends to draw in a larger base of retards, kewls, people who'll say 'YEH I CUD MAEK TEH MEFF', etc etc
It's rather undeniable that quite a few of us did start with BB related activities, and then suddenly felt the draw of those tasty organic molecules though, so obviously we should absolutely leave it to happen. I just don't think we should draw kids in with promises of explosives and drugs... sounds like a Faux news report and Zoklet getting an influx of retards / us being arrested for being terrorists/communists/criminals.

I don't want to draw more in, I simply was hoping to find a way so that those kidiots/kewls who are already drawn in, rather than making some ghetto AP and deciding to be delinquents, would take an interest in pyro and the like for what it really is: science, rather than making some ghetto AP and deciding to be delinquents. I can't speak for others, but I know pleanty of people who got curious, made some kind of IED, then just got out of it to go do other stupid shit. The trick is, IMO, when they (the curious kidiots) come around, we need to find some way to make it less about the bang and more about the engineering, so to speak. Unfortunately, I haven't the foggiest idea how.
It's rather undeniable that quite a few of us did start with BB related activities, and then suddenly felt the draw of those tasty organic molecules though, so obviously we should absolutely leave it to happen.This is what we need to look at. Something about us (the ones who stuck with it) was different. What made us really start enjoying the science? Were we all just naturally intelligent people? Or at some point did we think something that made us stick with it? I don't know. All I'm saying is that if there's a way to turn the inevitable kewls that come 'round into legitimate scientists, we should do it.
I just don't think we should draw kids in with promises of explosives and drugs... sounds like a Faux news report and Zoklet getting an influx of retards / us being arrested for being terrorists/communists/criminals.Ahh, yes... the fear. &T had this problem, IIRC. It was those damned text files (KFB!). Half the shit was cut straight from the anarchists cook book. With everything all spelled out, the standard kewl just makes some IED and doesn't have to think about it. All they think about is "where to I make boom-boom?" Take a guess where that leads.

It tends to vary I imagine... Different possibilities or combination's of them...
Perhaps at some point we all got really interested in something in particular... and went through MANY google search results pages learning a ton... Then we realized that that could be applied to a lot of the other pyro stuff and it kinda spiraled out of control from there...
Or we started reading a topic in a pyro forum and found it interesting... interesting enough to read more and more topics from the forum... spiraling out from there...
Or something else... Whatever it is we seem to all have a few things in common... like:
*We compulsively read ingredient labels on products unless we have read them before, or don't expect them to have anything of interest.

A true FAE involves two explosive charges and a fuel source. The first charge disperases the fuel source, the second charge detonates it.

There are a lot of interesting possibilities... Depending on if you want a fireball or more of a detonation.
I wonder what melted naphthalene with a charge to atomize it and a charge to ignite it would do... Just thinking... I know some of us have this shit just sitting around stinking up the place even through 2 ziplock bags. Its a stinky hassle to powder it for small mortar fired fire balls... but melting it might be less of a hassle.
Also along the lines of high carbon content fuels, I wonder about very hot melted wax.
I wonder about dissolving DBSP in fuels... It has both NG and NC and could possibly help contribute to everything getting burned up completely and a large volume of gases produced... IIRC NG used to be stabilized by dissolving it in acetone... If you used enough acetone to make it not detonate by the dispersion charge, it might be a good fuel. Then like mentioned on SMDB there are various nitrites like isopropyl nitrite that could contribute a bit of oxygen.
I dunno. Something about that video (is nice.)

Gasoline would be interesting to see detonated.
Back in my experimental (Dumbass) days, I made a rocket with AP.

That's not me, but it was similar to that.
Hey, nuclearrabbit I found one of your vids on youtube!
http://www.youtube.com/watch?v=hodaLEMW34g&feature=related
On the topic of plasticized acetone peroxide-
Very good detonation, and very convenient. I can safely report (heh) that a mixture of acetone peroxide and nitrocellulose (from ping pong balls) will detonate. Probably not fully, as i felt shrapnel (probably nitrocellulose), but I used too much NC, about seventy percent. Thirty should effectively plasticize the mixture, and allow a much more thorough detonation.
Add an amount of nitrocellulose, or sliced ping pong balls to acetone, along with equal, or twice the volume of acetone peroxide. Let sit until fully dissolved, stirring with anything that is not metal or soluble in acetone. Scrape into container of your choice (matchbox!). Let dry and have fun. I hear adding a sparkler while still gelatinous makes an excellent fuse.
asilentbob
04-30-2009, 04:44 AM
Technically you shouldn't do that... Some of the AP will dissolve in the acetone and creep up into the sparkler... And if a spark hit some of this early on... it might not be pretty. I do understand the novelty of being able to just insert the fuse and all and let all the acetone evaporate away over a few days so you have a solid package with everything there... But if its dissolved, its going to creep and you should really find a way to avoid that.

so I was reading some information on PE/chemical horn fuse systems and got an idea. If you were to take the chemical horn idea and put it in a rocket with a PROPERLY BALANCED charge in the upper body you may have a better way to do areal HE dets....not sure how you would get it to work, but if you could build it so the liquid in the horn mixes when the burst charge goes off it may be a cool idea. I don't think i would be brave enough to try it without a lot of testing, but im sure someone here would like to toy with the idea a bit.

Hai guyz, long time since I last ventured unto the smokey areas of chemistry. :)
Acting on a somewhat fortuitously timed urge, I decided to synth a smidgeon of nitrocellulose. All going swimmingly, even using really shitty quality H2SO4 (see picture) and NH4NO3 to make up the nitrating bath, but I now realise I have a slight problem...
Any tips for getting the fucker to detonate once dry & pure? I'm only going to have a very small amount, roughly 3g I reckon, might I have to turn to everyone's least favourite peroxide primary and make caps / mix 70NC:30AP?
That's a rather pointless picture of a sight ye've all seen a hundred times before. I merely happened to have my camera handy.

Good to see this place back.
Wasn't sure if this warranted a new topic or not, so thought I should just post here.
Friends birthday is in a few days. Another friend contacted me about an hour ago about giving him a nice present.
We're thinking several AP charges, total amount of A.P. being around half a pound. Around here, AP is basically the only [[Good]] explosive we can get our hands on.
So, at the moment, I'm just reviewing all my safety knowledge (Never know when someone's improved upon old techniques).
Is the generally acceptable method of storage still upside down in a container of water?
Any personal tips/experiences we all haven't already read a few thousand times?
asilentbob
05-05-2009, 06:01 AM
Best to not store it... If your going to make a bunch, dry it in separate piles. Don't store too many of them together in one place. Wear lots of protection. Cutting the AP with something else is always an option. If your not hand pressing the salutes, cutting it with something like saw dust may be a good option, should make things very slightly less sensitive. If these are big charges, and not just small salutes, you may want to fuse them only just before use. Or perhaps fire electrically. Be sure that there are no small rocks in the vicinity of the charge. Eye protection very strongly recommended.
Something easier and quite possibly just as satisfying would be flammable gasses in balloons (or a big trash bag!). Propane or acetylene for instance. Or oxygen and acetylene from a welder. You would have to be VERY careful with setting them off though. Maybe attach them to a post and use an e-match... Or better yet, a flaming arrow! Man that sounds so satisfying.
Edit: Theres some vids on youtube:
http://www.youtube.com/watch?v=a0PqmkKeNmc&feature=related
You also get the satisfying easily visible fireball with gases... you don't really get that so much with HEs unless its in really big quantities or slowed down on video.

Acetylene and oxygen is a deadly mix. The noise is insane for a regular gas explosion. Be extremely careful because acetylene has a very wide explosive radius.

When I messed with AP I just pressed small increments at a time lightly with a wooden dowl rod that fit the casing very loosely while wearing leather gloves... but if one had gone off it still would have been bad at that distance. The dowel rod would probably have shot up through the roof of the garage and fucked up my hands royally. If you have a hydraulic press you could press it with that and put some sort of barrier between yourself and the caps. If they are bigger than small caps I wouldn't try them on a hydraulic press though either...
If its large charges though it would be VERY hard to press them safely... I suppose I wouldn't worry about pressing anything.
Another option... is to make some MEKP and dissolve some of the AP into it for one of the bigger charges... its slightly less sensitive than crystalline AP and MEKP/AP is higher density so it avoids pressing all together. Actually there is a synth somewhere on roguesci that combines an AP synth and MEKP synth so that the AP dissolves into the MEKP as the both are formed. You could even add some AN so you sort of have a slurry. Then you just have to deal with MEKP being a liquid that can wick into fuses... So you could use an electrically fired AP cap or something that has been waterproofed somehow. Perhaps make your cap out of a length of polypropylene tubing with one end sealed or some other tubing that MEKP isn't likely to dissolve quickly... MEKP seems to act as a solvent about like MEK or acetone, so something neither of them will dissolve quickly should be good. When I made MEKP/AP I colored it purple with some drops of purple primer used for pre-treating PVC before gluing it together. IIRC I added it to it when I was synthing it for visibility.

There might also be a contest to see who has the best homemade BP for lifting an anvil with 1oz of powder. BUT I haven't determined if that is by weight or volume. No chlorine compounds, metal powders, nitro compounds, etc. I have a couple ideas, both standard and advanced... including one that I have been keeping on the D/L since I have never heard of anyone trying it (involves the nitrate)... BUT I don't think I'll be entering... Not enough time.
The BP contest sounds fun. I have over 40 variations to BP saved, and 3 original ones I made that work well. If you care to tell the one on the downlow PM me.

asilentbob
05-07-2009, 04:07 PM
Yeah, they would probably do something like that, then hydraulically press it into much more dense grains then break it up and screen it to whatever size.
I'd do something like that too, but my nitrate would be "different" before ball milling. Involves changing what the physical properties of the nitrate are at temperatures right before ignition of the mix.
Another option which I have thought of but never tested would be catalysts... Like iron oxides, copper oxides, manganese oxides, etc... I'm sure people have done tests like this before... I just have never seen or read about them. Could be that it makes the mix less safe for ball milling or something.

I'm a mod now! :) Went ahead and sticky'd the PRRT! I'm going to be cramming for finals and probably going to a small fireworks club shoot this coming week. Should have more free time about 1 week from today (Sunday 17th ish). (Though I can probably mod from my phone if need be.)
So... Back at BB aside from the PRRT we had:
*Informational Links thread
*Read this first thread
(somewhat rules / the generally accepted best way for noobs to start out with many links to beginner material (sites, books), OTC chemicals, safety, where to find your local laws, some common abbreviations, why ACB sucks, etc.)
*Contacts thread
(sorta floated around and seems like it got bumped about 2x a year.)
So, think about that stuff and more. For the links thread, if someone has a copy of the old one, that would be great, just post it as a new thread and I'll sticky it at some point and we can just keep adding links... This would probably be the best start. (Wish there was a strikethrough font we could use for dead links... Or maybe just move them to a later post in the thread and use a different color text.)
Otherwise I might have to try to export my firefox bookmarks, edit out a ton of shit by hand over several hours, and then go into a good text editor and find and delete like all HTML formatting tags to have just nice links... I dunno, there is bound to be a better way.
If someone wants to start a contacts thread, go for it. A few of the BB regulars are on IRC nearly all the time in #totsebb on irc.slashNET.org. There was a problem for a while with nickserv being down and no one being able to get into the room because it was set to identified people only. Might be fixed now, dunno. We sometimes do group Skype conferences randomly, but its been a while. So if someone starts a contacts thread, might want to note that.

One of the awesome things psyco_1322 and I got to see at PGI 2008. This guy has a horrible camera arm though. He was just a spectator. Goes off 35s in. What you can't tell from the video... Is that the charges are not in a straight line, they are curved. Set off all at the same time so that if you are standing in the right spot you are supposed to get a little more of an effect IF all the pressure waves reach you about the same time and constructively interfere. It was awesome though, the video doesn't do it justice.

I recently came across a corning hotplate/mag stirrer, some 150ml RB's, one 250ml double necked RB boiling flask, a few odd peices (i think one is a membrane cell or maybe just a double phase separation thingamabob {its got a filter in the middle of a tube and some funky pipework on it} some ceramic erratta, a cool tube with a tube inside it (not a condenser) and some other shite im forgetting! oh oh a -30c - 150c german pyrex thermometer!
one word of advice... it doesnt matter how small an amount you use nor how far away your are from it..... dropping pure sodium into 30% h2o2 is scary!

not pyro related...more drug area...BUT i did find some cool stuff out last night. Glycerin helps speed up the absorption rate of chemicals though the skin by up to 200% then just normal water. If you mix it and mdma, it WILL absorb though the skin...just takes a bit of time depending on where and how much. Not sure what this does, but explanes how you get NG head so easy since it absorbed...figured it was a random bit of info...i dunno...have fun with it.

Thanks for posting this! Think dissolving MDMA in glycerin and then holding it under the tongue would be an effective method of administration?
lordnitrox
05-17-2009, 11:08 PM
I think it would to be honest...it would also help kill the bitter taste since glycerin is very sweet. The idea is to get the drug (mdma) in to the blood, and there are tons of vessels under the tongue..so would work. I did find it's not 100% right away (i used it on my wrist) and there is some lag time, but a better medical solvent may change that.... Im going to try it with DMSO when I can get more MDMA to see what that does...was thinking it could get fun trying to make patches that stick to the skin with the idea. like I said, just random bit of info have fun with it.

Sorry guys, I realize the forum has been slow. Been getting stuff around the house done.
Started fermenting another gallon of hard cider. Started 1 gallon of chile pepper honey wine. Chile mead. Capsicumel. Worked on planting pepper plants and setting up a drip irrigation kit from harbor freight which promptly announced that it is a defected piece of shit and crapped out. Spent some time in the garage looking around at what all I have around. Lots of stuff.
If I don't get a call about getting a job tomorrow morning I might make some more hydrazine sulfate. I have a bunch of bleach just sitting in the garage as well as some ammonia and urea. Or maybe some urea nitrate to nitrourea to some other high nitrogen goodies I can't remember... Or maybe I'll do some pure pyro work... Work on the star roller... Mill some charcoal... Find a use for all these damn flares that are past their expiration date... Check up on how the fire extinguisher is doing... I dunno. Probably burn up some of the trash and old compositions that I have around in very small quantities. Summer cleaning.
I need a job soon though. I'm pretty much broke. :/
UPDATE: Ended up making urea nitrate (precipitating) via sodium nitrate, urea, and hydrochloric acid. Going to dehydrate some of it to nitrourea at some point. Then going to take some of the nitrourea and reduce it with Zn/HCl or something to semicarbazide. Then take some of the semicarbazide and react it with formic acid. Then take the product, triazolone and react it with nitric acid to form 5-nitro-3H-1,2,4-triazol-3-one (NTO (http://www.sciencemadness.org/talk/viewthread.php?tid=10913#pid132013)). Cool stuff. Depending on the yield of the various steps I might make some sodium azide from some of the semicarbazide. Haven't seen the mechanism yet.
UPDATE2: 5/27/09. Started working on my site again. Been going on for a few hours now. Mostly just editing info that is old that was there.

Transportation of Fireworks by Hobbyists
June 2009 Update: URGENT READING
By John Steinberg
This article has been vetted for legal accuracy and reviewed by PGI
Attorney, Doug Mawhorr.
If you are even thinking about bringing fireworks to the PGI, that are
regulated as explosives by ATF, please read this article thoroughly as there
has been a major change in rules interpretation and enforcement by ATF. Let
me also clarify and reiterate DOT rules interpretation which has NOT
changed.
DOT:
1) If you are NOT in commerce, DOT rules and regulations do NOT apply to
you. You need not have a CDL, placards, log book, MCS 90 insurance
certificate and $5 million in coverage, hazardous materials registration, etc.
2) If you are in commerce, you need all of the above and more.
Conclusions:
If you are bringing your own non-commercial fireworks to the PGI for your
own enjoyment, DOT has no issue with you and you have none with them. This
has not changed.
If PGI is paying you to do a display, EVEN if you are a club, you MUST
find a qualified means to transport your pyrotechnic materials to the
convention. This most likely means working with a display company as no club I know
of, including the PGI, can afford to become a commercial transporter of
display fireworks.
ATF:
Some history is required here:
On May 24, 2003, the Safe Explosives Act took effect. This required an ATF
license for ALL transportation of regulated explosives on public roads. ?
Public roads? means anything off your personal property.
A User Limited ATF license will allow intrastate transportation.
An ATF license, of any type greater than User Limited, is required for
interstate transportation.
In 2006, the ATF conducted an enforcement operation at the Appleton PGI
convention. Though no material was seized and no persons were charged, this
created a problem that we felt needed to be addressed.
To that end, on December 11, 2006, our attorney, John Brooke, Tom Handel,
and I met with ATF and DOT personnel at ATF HQ. Representing ATF at that
meeting were, among others, ATF Co-Chief Counsel, Teresa Ficaretta, Arson and
Explosives Division Explosives Industry Branch Programs Chief Gary Bangs,
and his immediate superior, Mark Jones, the Deputy Division Chief.
An agreement was arrived at, endorsed by ATF Counsel, that a member of a
club could transport hobbyist materials to a club event under the club ATF
license. An agreement was also reached whereby it was determined that
travel requiring an overnight stay would still be interpreted as transportation
and that no magazine storage would be required. Table of distances
requirements would be in force, however, but cars would not count as occupied
structures, so parking lots would have sufficed so long as the vehicle was
locked. The details of and permissions granted under this agreement have
previously been published in some detail and I will not reiterate those details
here.
Though we asked ATF to reduce this agreement to writing, no written
response was ever provided to the questions we posed. These questions have now
been answered in the June 2009 ATF Explosives Industry Newsletter.
For two and a half years, this verbal agreement was honored. No other
interpretation was offered and enforcement was consistent with the agreements
reached in 2006 by ATF and PGI.
DOT did not offer any changes in regulatory interpretation at this meeting
and none were requested of DOT by PGI.
The ATF regulation interpretation has now changed. The permissions
previously afforded members to transport under a club license have been
unilaterally rescinded and previous permissions granted must be considered as revoked.
If you are a non-ATF-licensed hobbyist:
1) You may continue to make and use regulated explosives for your own
non-commercial enjoyment on your own property and must comply with lawful
storage requirements.
2) You may NOT transport that material to a club event on the club license.
3) You may transfer your material to an ATF license holder. BUT, you may
NOT transport the material off your property to that license holder. An ATF
license holder may come to you, collect your material, create a record of
acquisition, and then transport the materials to his magazine, logging them
in properly. This is NO longer your material. The transfer must remain
NON-COMMERCIAL. No payment for this service may be made by you to the license
holder nor any payment made to you for the material. The license holder may
bring this non-commercial material to an ATF-licensed-club event and
transfer the material to the possession of the club. The club must create a
record of acquisition. If you are a member of the club, with the club?s
permission, you may then be allowed to fire said material at that club event. But,
the material can never be returned to your possession.
>From this point forward, with NO EXCEPTIONS:
You MUST have an ATF User Limited License for ANY intrastate (within your
state, crossing NO state boundary lines) transportation of regulated
explosive materials, whether in commerce or not.
You must have an ATF license, of any type greater than User Limited, which
is required for ANY interstate transportation of regulated explosives.
Further, as if that news were not enough, you are now in transportation
ONLY while en route and moving. Whether or not you are an ATF license holder,
if you stop overnight, your material MUST either be placed in a lawful
magazine or, in a locked and attended vehicle AT THE DISPLAY SITE.
I was pleased that we could work out the agreement that was in force for
the last two and a half years. I am dismayed that an agreement that worked
so well has now been unilaterally discarded without any consultation with or
communication to those affected, except as provided in the newsletter. But,
that?s the way it is.
Given the recent changes in ATF interpretation of explosives rules that
rescind these two key allowances previously afforded hobbyists as published
in the June Industry Newsletter, I think it would be both reasonable and
prudent to expect an ATF enforcement action at the PGI convention and,
perhaps, at other regional club activities. Thus, if you are not 100% certain you
are lawfully transporting fireworks (non-commercial, ATF license holder) do
not even think about doing so this year. If you can find a license holder
to come collect your material and are willing to part with it, as described
above, this is your only remaining option to be a non-licensed hobbyist
manufacturer and shoot your material at club events held at sites other than
on your property. Otherwise, your best course would be to obtain an ATF
license and a contingency storage letter from a license holder or to establish
proper storage on your own premises.
Remember, a license holder may still grant you permission to store
material in his or her magazine, so, while a license is required for
transportation, you need not have storage on your property. As an example, a member of
the Crackerjacks club could:
1) obtain a user, non-limited ATF license
2) make fireworks for his own enjoyment at the Crackerjacks club site
3) store the material in the Crackerjacks magazines, after obtaining
written permission to do so
4) then collect the material and transport it, without any DOT
constraints, to the PGI event or other event, so long as NO compensation is provided
for your doing so (you must remain non-commercial)
In closing, this is, in my opinion, bad news and certainly makes life more
complicated, but, for all but a few hobbyists, there are still solutions
that will allow you to continue to enjoy your hobby. Whatever you choose to
do, please do so lawfully. If you have any questions, feel free to contact
me by email. I will answer your questions and have our attorneys vet those
answers for accuracy.
This mostly just effects pyro club members who are not licensed. You can still do shit as an amateur legally... Like the whole make and shoot on the same day on your own private property granted there are no burns bans or other laws in effect, don't transport, enough empty space away from buildings, etc etc etc...
I've got some licensed friends, so I can still get stuff to club shoots. Its just more of a hassle now. Closer to PGI I think I'll just bring all my supplies over to the licensed friends place, build there, then leave all the supplies there if I can while I go off to do more college. At some point get licensed, start building again. Be happy.

Ya, that fucking sucks balls....I'm pissed.
Still even if you transport there, they log it in, and all you get to do is burn it, no takey back home with you. Looks like no cool stars...no big shells...everything on site? This is going to blow balls. Did I mentioned I'm pissed about this?
asilentbob
06-17-2009, 05:54 AM
I want to know what they are going to do about manufacturing... Because I could still make a bunch of stars and dry them at the licensed dudes place, get him to take them up there... but if i get a bunch of stars made and he transports them up there... am I going to just be able to burn them? Or will I be able to take them out of the magazine and build shells? Because they are not my stars anymore... they are PGI's lol... I'd assume I can still build on site... but meh...
Dude, if you want to try to just make everything on site, we probably could... IE right when we get there start milling the charcoal type star comps with both our mills, when thats done rolls the stars and start more BP milling at the same time for filler... And all the while pumping/rolling/cutting other star comps... So by the end of day 1 we have most all our comps/stars/filler made... For lift... err... well last year there was a bucket of good lift BP that some club had that they let me use a bit of for that big shell... but we could probably mill and press/granulate our own since you have the hydraulic press... we would just need to get the pucks made nice and thin and drying on day 1... For whistle fuel you could do that really quick no flame double boiler way and evap the acetone away fast... but I dunno. Any flash inserts we would need to make prior and get a licensed dude to transport for us... I kinda want to make a large non-flash item for the ground salute range assuming there will still be one... But I dunno what... Some weird composition that no one would suspect to generate a large volume of gasses or something that I can make on site and that isn't sensitive... I'm low on the nice "all gasses" perc though :/... Finally... I have no idea how I'm getting up there... I'd assume the same way as before... but I don't know when we would get there, and I guess we might have to make the "big" stuff earlier at the licensed dudes place...
There is going to be a lot of guys from APC, we should all get pizza or something one day and chat. I know I have met a few of them in person, but I can't really remember them all that well.

Then let's make it. A few topics:
The NC I've made has always done the classic smokeless instant flame thing, but I don't think I've ever gotten a full det from it. Once I tried soaking it in MEKP and detting that. The MEKP obviously detted, but how would one know if the NC did also? Also, is another intermediary needed between whatever organic peroxide I use and the NC?
Also, is there any reason to do HMTD over AP or MEKP?
I've never had any luck with NS. Why could this be? Not even weak flames when I try to light it.
Did the MEKPNC make a bigger bang than the same amount of just MEKP would have? I'm willing to bet it did. The only time I've detonated NC was when I made blasting gel.
NC is hard to det because it has a low density. Getting a primary so intimate with the strands of cellulose ensures good shockwave propagation and desensitizes the primary. BG is nice stuff, but you can make other NC compositions the same way with things like ETN.
People seem to think HMTD has an advantage of AP because of its very slightly lower impact sensitivity. Though it is more reactive and the chems can be harder to source. MEKP isn't often used because it has a tendency to absorb in to things and that can be a very damaging behavior. One cool thing about MEKP is that it decomposes on contact with H2SO4, as seen here (http://www.youtube.com/watch?v=HEJAz32yc04).
The key to good NS is using a more soluble nitrate source, HNO3 being the best, but NH4NO3 works just about as well. Add the starch slowly and stir constantly to break up clumps. I think I read somewhere that potato starch is the best but I used corn and it worked fine.

My name is extinct, I met you at some point during the time I found the BB and joined and someone even said I had potential at one point.
When I found BB, I found chemistry. I realized I knew nothing worth knowing unless I knew chemistry. I went back to school and just finished Chemistry I and Chemistry II, Im taking organic I and II in the fall and spring. Now that I actually know what you guys are you talking about reading through I am absolutely amazed, astonished and confounded I am downright stupefied at how advanced and completely radically set apart your lives are because of this one thing. Understanding the physiology of working living things is enough of a reason to say that, but understanding the internal working structures of any situation fathomable is perfectly another. Now that I Understand to some degree the principles of chemistry, my life just suddenly makes that much less sense.
If all goes well, I am set to enter pharmacy school in 1 more year. Nova. seems pretty simple, the only thing that can go wrong is i change my mind.
I will call you misfits. chemistry should be the single most important thing in life, period. its what everything is. its why it is. at least, chemically. i read that life is certain non-spontaneous system sequences driven against the entropy of the universe by using chemical reactions that liberate heat to raise the entropy of the surrounding to compensate for the non-spontaneity shift. I actually understand gibbs.

Afghanistan is a great place to see some BIG ASS EXPLOSIONS, although some I really really wish I hadn't seen. The biggest explosion I have gotten to see is 300-600lbs of explosive which that was the one i kind of wish I hadn't seen since my Sgt lost his leg in that one(the trucks we drive are amazingly armored), the coolest one was a controlled det since no one got hurt and the smallest was the IED that hit my truck which was still big but inside our trucks it just sounded like someone farted :-P

Nope, before now I've always diluted it like 10x before basifying, otherwise the CO2 you get upon adding sodium carbonate until its basic can be easily enough to froth out of the beaker. Also it takes a fucking ridiculous quantity of Na2CO3 to basify 65ml of 95% H2SO4!

ATTENTION: New idea to keep some threads clean-ish. I'll move SOME of the worthless posts to a worthless post thread, instead of deleting them. This is an experiment. Don't expect me to go through every fucking thread doing this. Also, non-BB regulars. Don't test me. I'd like to not have to moderate at all.
More news. Ummm Halloween is near. Make some alcohol borate esters?

I trust you asilentbob :thumbsup: even though I don't visit this section as much, maybe cause of the questions asked these days could be solved by a quick google. Cool though.

Happy new year everyone. I hope everyone has some good pyrotechnics going on this year! I use to be a BB regular ( had a different username on totse). I'm not into pyro much anymore, got sucked into the dark side of chem (durgz), but I ordered some chems from united nuclear this year and decided I'd make some flash salutes, star mines, etc. I also have a pound of pyrodex (don't have a ball mill). No high explosives this year, I got tired of risking my limbs.
But anyway, yeah, I hope everyone has a safe and happy new years eve. Nice to see the PRRT is atleast still somewhat alive.

I spent the new year's in Germany and damn do these guys know how to do it right. I've never seen so much smoke from so many people lighting shit that the streets were thick with it. That smell... Ahhh... :) Takes me back.
My wife and I should be going back to my ol' home for the 4th this year so we'll have a good time then too.
Oh shit I'm a mod. :eek:

I has an idea. Ya'll know what tornado tubes are right? Well fuck you 'cause I'll tell you what they are.Take two 2L bottles and their caps. Place the caps together with the open ends that screw on to the bottle out. Now wrap some electrical tape around the two caps to secure 'em together. Punch a hole through the center of the two caps so you've got a little tornado tube.
Here's where my ingenious badass idea begins. Screw the two attached caps on to an empty bottle. Take another bottle of the same size and put something you want to filter, like AP or summin', in it. On top of your empty bottle you have an upside down cap for this suspension to be screwed in to. But you wanted to filter it right? Stuff a cotton ball in that cap and let the liquid drain off through it in to the lower bottle. You're gonna have to make a little hole in each bottle for the pressure to equalize as it filters but oh my damn that's a good way to make sure you have everything out of the liquid.

^^Got it, thanks, seems very appropriate for someone like you - as I've always said "a tattoo should mean something to the person having it"...
Well, congrats mate.:)
PS: Reminds me of a DK pyro technician who had the old school "warning - explosives" sign (where I'm from that's a pictogram of a narrow mouthed iron pot with flames coming out at the top) tattooed on his bicep, the last three (personal ID) digits of his pyro cert across the belly of the pot.

My stencil wasn't the best and I oversprayed a bit, but I think it looks awesome.
