looking for smokeless flash powder recipe


My trained pigeon lit off maybe 2 oz flash powder in open
Usually just a brilliant flash, and a big pillow of air. This time, however, it sounded as if a 500Lb bomb went off. Neighbors came out, and so did I, so as to lessen suspicion. I just can not believe how fucking loud that was. I had no ear protection, and I bet I destroyed some inner ear hairs.

So today <24 hours after incident, I made an emulsion of vitamin A acetate, lutein, and ascorbyl palmitate, DI water, ascorbic acid, polysorbate 80, salt. I have been instilling these drops into my ears, In hopes of hair regeneration. http://www.ncbi.nlm.nih.gov/pubmed/9581394

My pigeon is just not certain how this may be able to reach the fluid the hair cells are bathing in. My hope is for a small amount to cross the phospho lipid bi-layer. I have all but ruled out DMSO.

I'm a guinea p:oig, somewhat, but I'd be an even greater guinea had I not taken action within the 48 hour window of opportunity

Interestingly, my tinnitus seems to have disappeared ~75% perhaps, which is huge. My sense of hearing is SO precious to me.

BTW: Any smokeless flash powder recipes. The smoke from KCLO4 & blackhead aluminum gives away my location. Still want stability and similar power if possible. Thanks in advance.

In about 4 days, I'll be in the same boat with ya mate.


If you want flash without the boom, then try more and coarser aluminum.

What boat is that? Prey tell you don't do what my pidgeon did. It made a super brilliant flash, but it wasn't so bright. I bet it reached > Mach 1. No casing, nada. In fact, it seemed much louder than a confined firework. Go figure!!!!!:mad:

How are you going to make an explosive with Aluminum or Magnesium as a fuel that doesn't leave copious amounts of fine metallic oxides hanging in the air as a "smoke" cloud?

If you want a silent bright flash, mix the flash with sawdust, increasing the percentage until you've got it denatured enough for your application.

As far as self containment leading to a report rather than a "WHOOSH", use coarser metal or a less lively oxidizer, or both.

2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

WHAT DOES IT MEAN TO SAY YOUR TRAINED PIGEON SET OFF YOUR FLASH????

He probably meant it literally. I have a neighbor who trains pigeons, those birds are quite smart as well as easy to get.
Buying a pigeon and training it to set off flash powder would not be that hard.
As for OP's question, there is no way to make a smokeless flash powder - only nitrate flash's give any gaseous products at all (nitrogen). Your flash will produce both metallic oxides and potassium chloride, two solids at STP.

"Flash" covers a very wide range of possible mixtures.

Ammonium perchlorate and Magnesium flash has a completely gaseous reaction product... The Magnesium oxide is a GAS at the temperature of that reaction. The gas output including the temporary gasses are greater than that of a similar weight of nitroglycerin, and the heat output per weight is also higher.

It makes some terrifying salutes. Because they are apt to set themselves off, unless the Mg is dichromate coated before mixing- Which process has its own set of hazards (hexavalent chrome, anyone?)

I have seen these made and used. The effects were dramatic, but not worth the risks and not at all suitable for a commercial product in my opinion. NOT RECOMENDED. Particularly not for the beginner. And the Magnesium oxide quickly condenses into a cloud of particulate "white smoke".

Cool, thanks for telling me that. Very interesting.
That gives me another excuse to make some more ammonium perchlorate!
