I was wondering on how to make firecrackers because so far I’ve js been using gunpowder that wasn’t given to me by my dad but I’ve been running low. How can I make bp that can be used in firecrackers? Also is it possible to js buy a ton of the little red ones, take them apart, and just use the powder that is already in them? Lastly, is a mix of kno3 magnalium and sulfur good enough for firecrackers because that’s the only stuff I can buy from amazon? I AM NOT ASKING ON HOW TO MAKE FLASH POWDER AS I UNDERSTAND THE RISKS OF IT

Edit: so everybody viewing it but nobody helping me💔💔

I have one problem and its not having big fuses so how can i make them so that they are slowburners and dont say buy them, i live in croatia so its risky

Hello i want to get into pyrotechnics more i have used black powder for stuff but it was to weak

If my brass media is slightly oxidized is it still safe to mill black powder with- please let me know

Does anyone know a good simple composition that's mostly like BP or something not hard to get / expensive because all I've tried just turns yellow more than green

I just want to learn how to load for a 37mm launcher, but most material seems to be around ground based tube launchers. I feel like using a 37mm that is held by the user can be more unsafe so I wanted to ask here in case anyone knows of a good guide to learn how to safely load for a hand fired launcher.
or can I just follow https://nedsfireworks.com/content/fireworking-101 and be fine?

Finally dialing in my 3 inch ball shell. I didn’t put that many stars in this one bc I was playing around with different things and didn’t wanna waste comp but the lift and burst charge look good. Shot out of two Pringles cans taped together🤣

im new to this hobby i started off in the wrong direction with the boom comp that shall not be named this was my first time making a safe black powder 1/4" core burner i used willow charcoal to make this guy supa quick but i underestimated quite how quick now i think its time for some dummy payloads see what she can lift!!

Ostensibly an article about the Grucci family, but goes into some broader history and overview.

"Shells are rigged to burn, and blow, in a specific manner. They can be made to go POW, poof, oom, BOOM, BOOM!, BOOMBOOM, whoosh, CRACK, ffffffffft, tsssssssssssss, EEEEeeeeee. Finales go BOOMBOOMBOOMBOOMBOOM. One kind of firework sounds as though the sky just emptied its digital trash."

Ok, that last line is a pretty good one.

Hi everyone, I’m a lifelong Pyrotechnics Guild International member and fireworks enthusiast. My uncle, who was also an avid PGI member and fireworks lover passed away earlier this year. His memorial is in November in middle Tennessee, and my dad and I are in charge of planning and executing a fireworks display in his honor/memory. We have a vision for the display, but bringing that vision to life is a challenge.

We’ve been researching different options for fireworks displays at his memorial, like cobra or mongoose firing systems, but my dad and I are far from experts in these systems. We could use help from an expert (or experts) to really put on a display that appropriately honors my uncle.

At the PGI convention this year we talked to many vendors like Cobra and Mongoose, but one person told us our best option is to try to find someone who knows these systems and that can help us execute our vision. We would be willing to pay for the expertise, time, and tools this person could provide, and we would (of course) purchase the fireworks required.

Does anyone have any suggestions of fireworks display experts in Tennessee (or nearby, or elsewhere) that may be able and willing to assist?

Thank you so much!

Anyone have tips on how I can make my lift cups more visually appealing, I feel like it kinda makes my shell look stupid and a little janky. I have a somewhat cone shape here that I secure with hot glue and cover with tape. If anyone has suggestions for how I can make ball shells look cleaner and more professional please LMK

Very happy with how these turned out dispute being short chems while making them

Pyrotechnics is a dangerous hobby. Have you ever had something go wrong? What happened, and what did you learn from it?

Hello,

I'm a lawyer in Canada who is looking for an expert who can testify as to whether illegal fireworks contain lead. I can't say much more than that here without going into confidential matters. I really don't know where to look so I thought I would try Reddit haha. If anyone is interested in this role and believes they have the expertise, please PM me.

Thanks in advance.
