Ahhh, I feel special, getting congradulated for staying alive a year longer. Today shall be quite fun. I have a nice 2" mine, a few salute (yeah, big woop, fun underwater though ) and 60 grams of ETN that should be almost dry. Tonight will be fun!

 

Now then, I should get a steady cash flow later today, so what should I buy? Chems, parts, what? So far I want a butterfly knife, just because they are cool, but what else to get? Any ideas

Is it possible to make any good flash from Ti and KNO3? I am short of oxidizers where I am right now but would like to make some bright salutes. The Ti is in dust-form and so is my KNO3.

Any suggestions?

While the orange peeling story may not be true, some of the ones where you think you can fly are. LSD messes with you perception of heights. You think, oh shit, I can't jump down this cliff, it's not that far. I've heard first hand stories from a person many of you know and respect that he has gone mountain biking on acid less than 2 feet from a cliff. He says it really doesn't look that far, and sometimes he thinks he can jump down it, but better sense tells him not too.

I have done psychoactives in my days, but I have never been so tripped out that I have done things that crazy. But I am aware that some people get so tripped out that they don not know what they are doing.

I guess Salvia or DMT is worse than LSD, cause while on LSD your mind is somewhat clear and you still remember that you have taken a drug, while on the first two you often forget that!

So just some auto repair place? Where do the filings end up? I'd imagine they wouldn't be that great swept from the ground contaminated with other things...

Thats not to big of a problem. Fe is magnetic, so its easy to seperate from dust etc.. The only problem is if there is a lot of steel in it. If they ask what your using it for tell them its for your rose bushes, and if you get a bunch of it, actually use a little bit in your rose bushes. Does wonders in some cases.

Has anyone here used Spatula Tzar's battery disection to get zinc? Is it pure enough to use for zinc\sulphur flash? I just tried a batch and it didnt work at all. I would have better luck lighting cement.

You can’t move during a dmt trip. So it less so than acid. Also, with acid you can relapse after many months of not taking the drug. Which can happen at very inappropriate times (like skydiving).

Simple question here....

 

Just how powerful a dessicator is glycerin? If I put it in a seal a bag with dilute H2SO4, will it absorb the moisture. (Im thinking no....)

 

And If I put it an a seal a bag with Sodium Silicate and a bowl of water, which will absorb the water? And id the water is absorbed by both, which one will steal it?

 

Does that make sense? Sorry if I am not getting through

Do chrome coated steel barings pose a big spark hazard if I use them to mill Mg, Al or Mg/Al?

[_DB_]

According to United Nuclear chrome balls do carry the hazard of sparking. Personally I would not use them.

[justanotherpyro]

Generally they are fine for milling metals because metals won't ignite from a spark. There is always the chance of having problems though.

I believe those are what Bob Forward was using to mill some Mg into fine mesh powder. After he finished the milling, he was dropping the balls back in his jar, and the residue of Mg powder in the jar and on the balls ignited and fried the skin of his hand to above the wrist. That was just from the 'dusting' of Mg in the jar.

[BigBang]

The Mg dust "explosion" he had was most likely caused by the impact of the 1" balls he was using, or so has been said. I have heard of many people using such media and not having problems, but ofcourse, there is always some risk involved. It is ultimatly your decision. If you d choose to use that media, do your milling away from anything flamable. Also, don't drop your media into the jar. Gently lay each one in.

 

And, you could use brass hex. It is sposed to mill nicely and is nonsparking.

[Mephistos Minion]

Mg ignition is the last thing I want (duh) so I guess I will look for some brass Hex. 3/4" be ok in a 4" barrel?

[TheSidewinder]

That may be a bit big. I use 3/4" in my 6lb Lortone jar. It's a roughly 7" diameter by 4" high rubber tub.

 

By "4-inch barrel" do you mean 4" diameter? If so, 3/4" will be too big. Try 1/2" or 5/8" maybe.

[BigBang]

Still add a few 3/4" media. It is oo big to use all by itself, but by adding small media with it, the milling should go faster as it becomes more efficient.

Any grandoise plans floating around for easter weekend?

[BigBang]

But ofcourse. I have a nice 20g ETN charge, A comet, red, and a starmine ready.

 

I'm testing a few smoke comps and like the one posted by Po a while back. Made a little one with a pice of 3/4" PVC and 30 grams of comp. the tube was about 3" long. I lit it and it burned amazingly, with thick white smoke. It did however burn with no smoke and a small orange flame. This is due to my nozzle not being the best. Anyways, It smoked perfectly for the majority of the burn. It well, just kept burning. At about the 2 friggen minute mark, the tube began to expand. It slowly grew as if someone was blowing up a balloon. At 2 mins 15 seconds, a small hole opened relieving the pressure harmlessly with a bit more smoke. It finished birning a good 20 seconds later. I thing I will start making fatter ones, instead of long ones, just because nearly 3 inutes is a bit much.

I am making a new ball mill. I am taking pictures. People may be drooling by the time it is done. It combines a ball mill capable of handling 7 pounds of BP, and a star roller all running at once.

[Givat]

WOW mumbles, sound like huge hybrid.

Don't you think it's a little dangerous ball milling so much BP at once?

I know ball mill accidents are rare if one use only sulfur, KNO3 and charcoal, but if one acour I founnd this realy dangerous. I'm using ball mill capable of milling 2 pound of BP a time and its already scary to use it.

 

Guess you got big plans for this baby, be carefull =]

[Mumbles]

I won't actually be milling that much BP at time. If I wanted to I could though. I don't use nearly that much BP. 7lbs would probably last me all though my 4th of july preparation. The large capacity is mainly for powdering chemicals, such as charcoal.

I have a quick question about chlorine donors. I saw the picture of the Shimizu Blue #1 star in the compositions and I ordered the chems to make it that I don't already have, except I forgot to get parlon, but I did order PVC. I found a table on skylighter that gives the chlorine percentages, and based on the amount of chlorine each donates, I tried to calculate how much PVC I would need to substitute for parlon. I got 15.2 parts PVC to replace parlon, which is about 14% more. Could anyone tell me if this would be correct?

The chart I found is here http://www.skylighter.com/skylighter_info_...cle.asp?Item=15

[Mumbles]

Eh, it's worth a shot to try it. Try a small batch. PVC is more flammable than Parlon, so that won't be an issue. Parlon is actually fire retardant.

[Pyrohawk]

I've substituted PVC for Parlon before. Just use 20% more PVC than you would Parlon. So for Shimizu's blue:

KClO4………………………….60%

CuCO3………………………….12%

Parlon…………………………...14%

Red Gum……………………......10%

Dextrin……………………...……4%

I would change the Parlon to PVC: 16 or 17%. My figures actually came to 16.8% but I like to round because my scales arn't good.... I'm interested how you came to your number? Anyhow, than rebalance the comp. and try it out. Something like this.....

 

KClO4………………………….62%

CuCO3………………………….12%

Parlon…………………………...17%

Red Gum……………………......10%

Dextrin……………………...……5%

 

 

Edit: My substituting worked (not this actual comp.) and I didn't notice any problems..... It might also take fire easier with PVC.

[ULTRABUF]

Well, I cant try it out yet. I just sent my order out I think on Tuesday. But I got my numbers in a rather simple way. Since the Skylighter chart said that parlon gives 64-68% chlorine, I averaged it to 66. Then I did 13.1*66 to get an idea of the total chlorine given off, and I got 864.6. Then I divided this by 57, which is the percentage for PVC, and I got about 15.2. It may not be exact but considering I didnt do any complicated math I got rather close.
