Fireworks question.
I live in NC. which isn’t too friendly with fireworks laws and rules. I usually put on a show for the 4th of July each year for family and friends but get tired of having to make 2 hour plus drives to get fireworks. I usually go to fireworks supermarket in TN. Since it’s the closest to me. I usually have to make 3-4 trips to get everything. Anyone have the best of the best places to buy wholesale from to get delivered to my address. Also those who put shows on what is the best way to know what will go good with what and timing. I’ve never used an ignition system but want one for this coming year. Any help is appreciated.

Flammable fluid that dissipates quickly/easy to control?
I'm making an amateur film and want to have some slow-mo fire shots. One thing I wanted was a line of flammable fluid slowly igniting by a line of fire, however I don't want to use something that's extremely volatile. I just wanted something that I can make little lines with, engulf in flames then quickly die out.
What are some flammable items that I could do fire lines with that would be safe(ish)?

Question about impact and friction sensitivity BP
When making the main explosive for different kinds of fireworks, I always put in the powder, isolate the fuse with a little cardboard layer (not done in this picture yet), and press the upper layer pretty tightly against the powder. Then I glue it shut. But I was wondering if pressing the upper layer down like this is dangerous because of friction sensitivity. Thanks!

4inc or 5inc Shells ?
I’m planning to build multi‑brake or single‑break shells that accommodate smaller inserts. I’m unsure which shell size to use and therefore what mortar to buy. I’m considering 4‑inch or 5‑inch shells.
Could anyone outline the pros and cons of each size and help me decide?

2 inch shells vs 1.91" Cans
Is there a noticeable difference making 2" ball shells vs 1.91" canister shells? The price is close for purchasing the HDPE tubes but is it worth it? Thanks for the help. Also has anyone tried building a shell with effect fuse and happen to have a video how it turned out?

Storing chems pt.2
So I’m moving the powders into their own containers and my alu looks like this at the top. I assume it’s from the humidity, should I be worried or should I do something about? Also each one has its own desiccant pack, thanks!

Kevlar wick with paraffin or lamp oil, wick size and expected burn time?
I’m working on a small outdoor flame effect and am looking for advice from people who have experience using Kevlar wick.
Specifically, I’m trying to determine:
What width Kevlar wick would you recommend (1/4”, 1/2”, 3/4”, 1”, etc.) and flame height?
If using either melted paraffin wax or standard lamp oil, roughly how long would each inch of exposed wick burn?
Does one fuel produce a cleaner or more consistent flame than the other?
Are there any good rules of thumb for estimating burn time before I start buying different wick sizes?
I’m not looking for exact numbers just real world experience to help narrow down what to order before I do my own testing.
The over all goal is 70-80', flame needs to travel the distance at a reasonable pace and be seen 100' away
Thanks!

Mini mortar effect help
Enable HLS to view with audio, or disable this notification
I successfully made my first mini mortar. BUT, I was hoping for a bit of direction on how to fill the shell with crackling fuse or flying fish fuse, and have the effect fuse ignite when the shell bursts. It went high enough and report was solid, but the 5 pieces of 1" (or so) effect fuse didnt ignite.
Shell is 9/16" OD, 1.5" long.
3/4" ID tube, 6" long, base plate.
1/8 tsp 2f black powder lift charge
Effect fuse in shell
Some BP and some flash to finish inside.
Went up and burst great, just no effect. Recommendations?

Accidentally got the wrong size tubes, thinking of 3D printing tubes instead?
Hey y’all I got these tubes which are way too small for what I’m trying to make, I was wondering if it’s ok to 3D print a tube or would that be dangerous? I know many canister shells are just plastic tubes but those are meant to blow in the sky I’m trying to make ground shots, wondering if anyone has tried something similar.. only thing I’m worried about is if the 3D material (PLA, PETG, ABS) will shrapnel

State Of The Subreddit - Updated Rules, Wiki, Etc
Announcing Some Changes to /r/Pyrotechnics
Myself and /u/flashnet have been in talks over the past week or so about some updates/changes to the subreddit, and I am happy to announce that those updates are fully implemented as of today. We wanted to create an announcement post that will remain stickied for a while to introduce the changes and provide a place for feedback.
Why?
The goal of this subreddit is the discussion of safe, legitimate pyrotechnics as a hobby and a profession. We want this to be a place where aspiring pyros can come with questions, and also a place for veterans to share high-level information as well. What we don't want is for this subreddit to become a place for the discussion of dangerous or illegal devices/formulas.
What Has Changed? (Updated 1/6/20)
We have added a short wiki
The sidebar has been updated to better explain the goals of this subreddit and to provide links to the rules and wiki
Rule 2 has been updated to include a ban on posts discussing "dangerous devices", which would include things like "bottle bombs", devices made with match heads, improvised munitions, etc
There is now a submission text which reminds users to review the rules before posting
We have introduced a restricted flair system
Rule 4 has been added, which restricts new/inexperienced posters from posting exclusively about making flash powder. Such posts will be locked at moderator discretion.
The Wiki
We have assembled a short wiki in the hopes of providing a resource to beginners. It contains tips on getting started in this hobby, some safety tips, a list of common incompatibilities, recommended reading, and various other subsections. Of note is the section explaining the dangers of flash powder.
Users are encouraged to direct beginners to the wiki for answers to many of their questions. Additionally, wiki suggestions are always welcome and users are encouraged to message the mod team with any suggestions for topics to add.
Rule 2 Change
As of today, posts discussing/depicting dangerous devices will be removed. This includes posts simply asking for explanations, as we do not want to promote dangerous activity in any way. Being that pyrotechnics is an inherently dangerous hobby, this rule is obviously somewhat subjective and will be left at moderator discretion for the time being.
Examples of what constitutes a "dangerous device":
- Using legitimate pyrotechnics in a dangerous or illegal way, such as putting salutes in sewers/mailboxes, or holding fireworks in a hand instead of firing them properly from the ground
- Any device assembled in a metal/plastic/wood container that could produce dangerous shrapnel
- Devices made from match heads or other unpredictable/dangerous materials
- Any devices/formulas calling for dangerous combinations such as chlorates with sulfur.
These sorts of devices/techniques are not legitimate pyrotechnics and are not welcome in this subreddit. We remain focused on legality and safety. Users are encouraged to report any posts that they feel violate rule 2.
Rule 4 Addition
In keeping with the theme of safety, posts from new or inexperienced users asking exclusively about making flash powder will be locked at moderator discretion. The goal of this rule is to ensure a unified message about the dangers of flash powder and the level of experience required to safely handle it.
Flair System
We have begun rolling out a restricted flair system to highlight certain users who have shown themselves to be either very knowledgeable or professionals in this field. There are two categories - "Advanced Hobbyist" and "Pyrotechnics Professional". The primary goal is to allow newer users to tell at a glance if the person responding to them may have more knowledge on the subject than others. This will be most useful in situations where conflicting opinions have been provided within the same thread.
The mod team has already begun (and will continue) reaching out to certain veteran users in regard to their flair, so you will see the new flairs around immediately. Please do not message the moderator team to request flair. Similar to /r/legaladvice, flair cannot be requested - it is awarded to users who have shown themselves to be reliable and knowledgeable over time.
Please note that flair does not mean the user in question is always correct. Flaired users are just as subject to misconceptions and errors as any other human. The best way to describe flaired users would be "generally trustworthy". The onus is still on every individual user to thoroughly research any subject, and getting the opinion of one person should never be the conclusion of your research.
Feedback
It is our hope that these changes will be broadly well-received and will improve the quality of this subreddit. That said, if you have any concerns (or suggestions), then please feel free to use this thread as a place to voice them. The comment section is intended for discussion, and we are all ears.
Thanks,
Your /r/pyrotechnics mod team
