BombBuilder Posted October 25, 2007 Posted October 25, 2007 K, Im sure if anyone used to buy all their fireworks have seen a flashing type of firecracker. If you dont know what im tlaking about here is someone video. http://www.youtube.com/watch?v=Y3uCoLD7Kmw I was wondering, what are the best chemicals and the mixture amounts for making this firework.
tentacles Posted October 25, 2007 Posted October 25, 2007 That, sir, is a strobe. There should be some compositions in that section of the forum, but I'll pull up something not too difficult or esoteric: Shimizu White Twinkler: (this is actually a strobe star comp) Ammonium Perchlorate 60 Magnalium, granular, -80 mesh 25 Barium Sulfate 15 Potassium Dichromate 5 or Bleser #27 Ammonium Perchlorate 48 Magnesium, atomized, 100-325 mesh 28 Strontium Sulfate 19 Potassium Dichromate 5 Not 100% sure what the best binder would be for this comp, but you can probably use a 5% solution of dextrin in water, dampen and press into a tube - DO NOT RAM an ammonium perchlorate composition, ever. There's no reason you can't cut, roll or pump these either. Prime with something hot.
oriansbelt Posted October 25, 2007 Posted October 25, 2007 What your talking about is a strobe or flash pot, not a flash bang [grenade](those are used my military/police to stun people in a room that they are about to enter). I'm sure that there are a few different formulas in the Compositions section but here is the one that I've used before. barium nitrate 51kno3 7sulfur 19Mg/Al 18dextrin 5 I found it on united nuclear since thats where I started in the beginning and it worked ok, not quite as good as the ones that you buy but that might have just been me since it was one of the first formulas that I made. edit: darn tentacles beat me too it.
qwezxc12 Posted October 25, 2007 Posted October 25, 2007 ...Not 100% sure what the best binder would be for this comp, but you can probably use a 5% solution of dextrin in water...Do not bind AP and Mg/MgAl strobes with water! All of Shimizu's strobes, or twinklers, as they're called, use NC lacquer, 10% IIRC. Some of Bleser's strobes that use Barium Nitrate are bound with Dextrin and Water / Alc. but the one listed would certainly require not only NC lacquer, but coating the MG with DiChromate as well.
tentacles Posted October 25, 2007 Posted October 25, 2007 qwezxc12: I thought it should be okay with 5% dichromate in the mixture, but apparently not - thanks for the heads up.
Guest Mark_the_pyro Posted October 26, 2007 Posted October 26, 2007 Regardless of that video, real flashbangs are only a special formulation of flash powder. I can say more, but I won't for this kid's sake, bomb builder.....

Mumbles Posted October 26, 2007 Posted October 26, 2007 Kid, shut the fuck up. You have to be civil to people here. I'm not going to tollerate you being an imature little shit.
