mr.stijntje Posted December 6, 2006 Share Posted December 6, 2006 I've got the new fireworks-folders, and I can buy those jumping crackers this year! 100% ripoff, since they cost €1.50 for 5 crackers. I'll also try to make them soon. But that heap of jumping crackers looks cool Blaf! Link to comment
Warcore Posted December 9, 2006 Share Posted December 9, 2006 I made yesterday 5 of them, and lighted 2 of them this morning. Those little basterds are damn funny Have to make more of them! Link to comment
flame on a stick Posted August 23, 2007 Share Posted August 23, 2007 i had a go with this and it worked ok, although it only banged twice and it was a 5 bang cracker. it did burn all the way through so i think it was low quality BP that caused it to fail. i will have a fillm of it on you tube in a few days under the name of 'rapidrory' Link to comment
breezer Posted August 24, 2007 Share Posted August 24, 2007 You have to add quite much powder in 1 snapper (althought more than i thould) But it worked fine maybe its a fun idea to connect a 7 snapper on a bigger cracker, so you would first get 7 snaps and after that a short break followed by a bigger bang.

mr.stijntje Posted August 24, 2007 Share Posted August 24, 2007 Makes me think of the illegal "italian bombs"... But they make it somewhat overdone with 40g of flash after the seven-cracker.. (Never saw one in rl btw) Link to comment
Guest Posted August 24, 2007 Share Posted August 24, 2007 Hmmm, i think i will try this device with H3, i don't have a ballmill, but i think my H3 will suffice...(can't spell) Only have to cover the fuse with paper so it won't come in contact with pottasium chlorate.(meaning the sulfer) So it will be storable... BTW, in Holland i think i never saw something like this, maybe jumoing jacks, but i think unpredictable shit is illegal, puh me of a cliff if i'm wrong. Latterrzz Link to comment
miech Posted August 25, 2007 Share Posted August 25, 2007 Just dip one end of your fuse in some relatively thick NC lacquer. This will prevent the sulfur from leaking out of the fuse. I'm gonna make some of these things too. They seem very funny to me. Link to comment
night hawk Posted August 25, 2007 Share Posted August 25, 2007 @ pepcore These things can be bought at any fireworks shop, they're called "zevenklappers", they're exactly the same as described here only they bang 7 times and are made out of green craft paper. Cya, Night Hawk Link to comment
breezer Posted August 26, 2007 Share Posted August 26, 2007 Could someone tell me were these jumping crackers crack? is that in the middle or on the side Link to comment
chemicalbrother Posted August 26, 2007 Share Posted August 26, 2007 In the middle and somethimes at the side but I think it's important how good your MP is. I think if you have good quallity MP the snapper crack at both places. Why do you want to know it? Link to comment
breezer Posted August 26, 2007 Share Posted August 26, 2007 Was just wondering why the string would be needed. Link to comment
chemicalbrother Posted August 26, 2007 Share Posted August 26, 2007 To holds the bend's! If you don't have a string the cracker will stretch with the first crack and if it's stretched, it doesn't work anymore. I hope I'm clear. Link to comment
Keesthemad Posted August 27, 2007 Share Posted August 27, 2007 Hmm, interesting, how would such device function when flash would be the used sas? Link to comment
chemicalbrother Posted August 27, 2007 Share Posted August 27, 2007 Maybe it's better if you keep the BP idea but put little flashheaps on your black powder line at the crack places. Link to comment
Keesthemad Posted August 27, 2007 Share Posted August 27, 2007 Yeah, that's just what I meant. The flash powder is just to make a nice edge to the bang. Link to comment
breezer Posted August 27, 2007 Share Posted August 27, 2007 I think it's real hard to put flash on exacly the good places of the cracker. Dont use chlorate flash! I was thinking if gleuing would be a good idea, I mean what would happen if you would gleu the whole paper and than quickly tie it? Would it crack louder? Link to comment
mr.stijntje Posted August 27, 2007 Share Posted August 27, 2007 Keesthemad, I think the flash would penetrate the next layer(s) at once, it could kill the effect. But if youv'e got Ba(NO3)2 or KClO4 flash, please try it. And let us know. Link to comment
Keesthemad Posted August 27, 2007 Share Posted August 27, 2007 I've got some Ba(NO3)2 so I could try to, ill make the composition 6:3 Oxidiser:Fuel, since it is already filled with black powder the flash should burn without doubt. Link to comment
Pyrostar Posted September 11, 2007 Share Posted September 11, 2007 Hi all May be a 7/3 KNO3 and Magnesium mixture would be ideal, because it doesnt burn that fast. Pyrostar Link to comment
Yawznug Posted July 15, 2008 Share Posted July 15, 2008 Flash powder would destroy the casing, there's no point really thinking about it. Sorry for bumping an old topic but I gave this project a few attempts to find them all unsuccessful. I find that you would need a very thick layer of black powder for it to work. Using this method mine only sizzle through the paper. But then I just decided to get some meal and make a line of it and fold it. (So no wetness). I glued the ends shut with the fuse in one end and then proceeded to fold it into a zig-zag. Later that night, due to the fact it does not need to be dried. I tested it and it worked perfect giving a loud bangs and actually jumping. So if you could not get it working I recommend trying this way. But this does have it's downs... the black powder can move and fall out. But if your careful and can fold it without moving the black powder side to side this method should work. Link to comment
miech Posted July 15, 2008 Share Posted July 15, 2008 I actually use five stranded quickmatch for making jumpung crackers. I think this is the most easy and reliable way to make them, although the delay between the bangs is quite short. Link to comment
Blaf Posted July 21, 2008 Author Share Posted July 21, 2008 I see some of you guys have doubts about details of construction. Someone mentioned a possibility of composition cracks when folding sections of the paper tube. OK, the angle shouldn't be steep, that's obvious and therefore I use ball-pen insert of 6mm diameter. I do bend the tube around this round body (which makes bends pretty round) and thus avoid cracks in still moist composition. Of course, thicker layer of wet meal should do miracles.

dilsssss Posted July 21, 2008 Share Posted July 21, 2008 Yesterday I made a bunch of these jumping crackers and found out you do not have to wet the meal powder. The only difference is that you must fold/roll it very tight so the BP won't fall out of it. I use this method because I don't like to wait for them to drie. If this isn't clear enough, please ask.
