Im a pyrotechnician. I set up and shoot class b and c shows and im also a member of a club where we manufacture and make our own from scratch. Its a lot of fun knowing you can make something not only explode, but do it with color and literally paint the sky with your handmade, personal design. I consider it artwork and its a huge passion of mine. I love this video. Its very well put together and very educational. A cutaway of a shell is really neat to see. You should make a video of a cutaway of some large cylinder shells to show the complexity of some of them. Those are very fun to make as well. Thanks again for the video!

@@Mental_Illboy You mean consumer or professional? IN professional there are probably no limits for that... I guess like 1000g salutes? But idk, im not a pro. In consumer fireworks the loudest one is not a shell, its a firecracker called Funkenschlag 10 by Funke. Ofc its not as loud as 1000g salute, about 100x less loud lol XD. Neh maybe not that much, but its still powerful. Its legal in all countries.

@matiam92 Yes, they are aligned inside the shell in the shape you want them to come out in. Often they are lightly glued to a piece of cardboard that is bent in the shape of a star or heart or whatever else.

They are regulated by weight. A lightly packed 3" would be acceptable, but there's a reason I said "approximately" in the video.

@DIChronicAddict1 Cool, thanks for the comment. I hope you learned something.

@versatilechicken In fact I made all three. I may be showing how to make the models in future videos. Many of the same techniques used to make them are also used to make real fireworks.

To learn the basics of what the stars are made out of, check my video How to Make Fireworks 101: Basic Chemistry of Compositions, then to see how the stars are formed check my video Firework Star Rolling Demonstration and Technique. The outside wall of these shells does happen to be cork, but only because that was the easiest material to work with when I made these models. The wall of real shells is made with two stiff cardboard or plastic hemispheres, then outer layers of glue soaked paper.

I would like to see how one of these black spheres burn, when ignited on the ground. :)

​@Shawn Stafford Stars, burning by themselves on the ground, look a lot like match heads burning -- only bigger and more energetic. They are usually laced with barium (green) or strontium (red) and so on for color. It's basically the colorant, black powder and a binder, usually gum arabic.

​@Shawn Stafford Star charges burn slowly with bright colors. Loud cannon with bright white explosion is the aluminum powder based "thunder" charges. These produce the bright white flashes without stars that we've all seen. Pop open a star charged mortar shell and light up one of the stars and you'll see what I mean. :-)

@rakoonpunk The black powder charge that is attached under the time fuse is what fires it into the air. A 6" shell can be 5 lbs or more.

@spamento It's easy to fill it with stars after it's been cut, the tricky part is creating the canisters to begin with, one on top of the other, spiking, pasting, then cutting down the middle. I would want some pasting cut away to expose the spiking also. I know how to get it done, but it will certainly be just as much work as building a real multibreak.

@marcomovies97 You do not need whistle or flash for any size shell. If you use quality black powder as burst and do a good job pasting it will work fine.

@Shannariano That is a business that you really need to know people to get into. First of all you need to study the law and learn every detail of how fireworks are made and the safety involved. Join a fireworks club and learn from the other members. There is a link in the video description that will be helpful for you to read.

@TomashPL58 A blob of hot glue around the fuse on the outside of the shell works just fine. String and paste is the traditional method, but it is not necessary. Because the size of the hole into the shell is so small, though the pressure inside a mortar may get up into 100 psi, the pressure exerted onto pushing the fuse inward is less than 10 lbs.

This was a good video to me. Not too long not too short just the right amount of information and depth for me. Thanks

this video is more educational than most! This video gives a very good description of the difference between wicks professionals use ("quick paper burns way faster than I was expecting!) and the thicker, green wicks they use for consumer fireworks! I also didn't know they could use gunpowder-coated husks instead of just full black powder, nor that the arrangement of the stars could change the "petals" of the firework! Great video!

@spamento Thanks! I would love to make a multibreak cutaway, I've been thinking about that for a while. It would be a lot trickier than these ball shells were, but worth it. We'll see if I get around to it.

@Finch723652 I do. The video description has some information about how you can go about learning to build fireworks legally.

@st1dinoh This is why hulls are good in shells. If you used granulated BP it would break just as hard, but then after the shell had exploded the granules would have only burned up their outer layer leaving the rest to be wasted by burning away in the air.

@st1dinoh The reason a pile of black powder might burn for slightly longer is not because it is burning slower than the same BP on hulls, it is because the granules have a duration of burn time just like a tiny star. If two piles are measured by volume of hulls and BP and ignited at the same time, for the first fraction of a second both piles will put out an equal amount of gas. Since the hulls only had a thin coating of BP they run out of it quickly, the granules continue to burn to the core.

@imnotrlly18yrsold drq40 is correct. The fuse is not extended because it does not need to be in order to reach the center of such a small shell.

This video was very well presented. Thank you.

This should be on the discovery channel. Thanks very much :D

Thank you for making this forty forevers ago. It is VERY fascinating and educational, indeed!

Very informative. Answered questions I’ve always wondered. Great presentation.

Best explination I have heard. thanks for posting this.

I had often wondered how the shell's were made, thank's very much.

I had help in setting up for fireworks shows, but this was a very informative video. I now know some of the dynamics on how this all works. Wish I could participate in doing shows again. Thanks

Awesome video! Simple, short, and educational. Well done and thanks.

@st1dinoh That has not been my experience. They don't burn any faster, or slower than granulated BP. There is plenty of space between granules for fire to pass through when not using hulls. I frequently break canister shells with granulated BP, which is what is traditionally done in such shells. The break is certainly just as hard if not harder than hulls.

@gabrielleb74 The shaped fireworks literally have the shape they make laid out on the inside of the shell. The stars would look like a smiley face rather than circles. I did not cut these shells in half, I made them like this. They also do not contain anything flammable, it is all inert material so they can safely be used for demonstrations.

That shell is a thing of beauty, fantastic job!

Wow! what a great explanation. Thank you.

I’ve always been interested to know what’s in there. Thanks, homie!

This is great! I love fireworks and this was very informative.

The best firework video ever seen. Thank you

this is the clearest , best,and most informative video i have ever seen good job

Thanks! I've always wondered how these fireworks are designed.

@ras464 A Sanyo Xacti vpc-cg20. It's a great camera for the price.

Excellent explanation.

@WhatAreYouBuyen Yes, it is a full sphere inside the shell. If the stars were only in a one layer ring that is the same shape you would see in the sky, not a full sphere.

@pyr0ph1L Thanks, I did make them myself. I have not decided If I want to sell them or not yet. They take a lot of work to make and so the price would be around $150 each if I did. If you are still interested send me a message and we can talk about it further.

Excellent, clear and instructional. Thank you.

Way cool. Always wondered how they work...thanks.

Very nice looking cross-sections and very good explanation of the workings!

Really good explanation. 👍

Superb description and examples. Thank you!

Thanks for the reply. I've noticed many of the big fireworks actually do look like a big 3D spheres when they burn, in contrast to just a ring. How do they do that?

Late to the game, but you are looking at a 2D cutout of a shell. A real shell has stars in a sphere all around the shell.

First off. Great video Hawk. Like your models. Everything is so well made. The most dangerous comp I can think of is Armstrong's mixture. Makes flash look mild by comparison. Really scary stuff. Not many people that have messed with it carelessly have survived with all their appendages.

Excellent video, I've always have wondered how it was done.

Great video. Thanks for posting this. Have a nice day.

by far the best explanation of firework shells on youtube!

excellent video. you are my favorite youtube channel you share so much information and must spend hours creating these videos for our enjoyment. thank you

Good overview, but I want to know what's in the stars and how is it packed. You pick the most awesome topics!

Very, very well done. You put a lot of work into it!

i dig your videos, man. although i already knew how they work, it was still a good video! it never gets old.

wow,i learn something new every time i watch one of your videos!

i have seen many videos but never got a video like this thanks

i really liked this. never knew how they worked.. i learned something and enjoyed it

That's right. The heart shape should be made instead of the circle. On the outside of the heart shape there doesn't need to be any more burst charge, so the extra space between the stars and the walls of the shell can be packed with inert filler, like sawdust.

Great Info Mang

@96ruly Well thanks!

Fascinating. Thank you.

Another great video

Definitely informative thank you very much

They do that because many Chinese companies use really lousy time fuse that has an above average likelihood of going out. Two fuses are also sometimes used on very large or complex shells, where there's enough money or work into the shell that a fuse failure shouldn't be risked even if using quality fuse.

Thank you for posting this as a scientist I really appreciate this

This is great Info!

though i saw lot of videos i was never satisfied with them , but i am really really satisfied with your video thanks once again

Fascinating. Thank you. 👍

Fascinating! Thanks

Very interesting to see how the star shells are made as you see them at all firework show and can only guess on the more complex ones are made.

So helpful! Thanks

hey great vid, verry informative and a great heads up for any kids( or adults) who find them selves in possession of a larger version w/ the quick fuse. as well as just in general. thanks

Great to watch.. Thanks!

This is really cool And i had no idea that that was how it all worked

beautifully explained

@kevinmeehan71 Kraft paper. Similar to what paper grocery bags are made of.

Great to see you doing fireworks again :)

So metal tube for mortar, short quick match fuse (since it's what the pros use) and some nitroglycerin soaked wood shavings. Got it! Can't wait to make my own fireworks! Just gotta find my hot plate for doing the nitration.

i loved that video please make more ! 5/5! fav

while in the Navy we did port calls in Guatemala. for a dollar you cold get a local kid to go get you a "boomba" they looked pretty much like these. we used to roll them inside of bars or toss them thru windows. Seemed like a perfectly logical thing to do at the time after several cases of beer. When it was time to leave town, we would all meet up and pay for any damages we caused. They usually ended up with better furniture and decorations than when we got there.

I'm not even interested in the topic but the explanation was very concise and easy to follow, thanks.

Are the stars packed into a sphere shape 360 degrees around the interior of the ball shell, or just a 2D circle? If sphere in a 360 sphere shape, how do you get them to stay?

Yep. Small shells require a faster burning break charge than larger ones because there is less volume inside. Smaller grains burn faster than larger ones.

Thanks for making this video! Really interesting! :)

Nice job NHIL! I like how the shells turned out and how you used plain English to present the terms we use in pyrotechnics. Now, all we need is a multi-break cylinder shell :-)
