How Fireworks Work

Good day! can i know why lift charge is confined in plastic?
Is this for additional protection to prevent the Lift charge from spilling when the lift cup is torn? Thank you very much

Please make some videos on making small shells like these and instruments and ingredients used in a shell.
And i really liked your videos
Thanks for sharing such beautiful information ❤👍

Thanks for sharing, explained very clearly and simply.

Can I use Nano3 in blackpowder. Cause other materials are not existed here.

That was a really good educational video. I learned alot.

I was a nuclear weapons specialist in the Air Force. Thank you for the video. Always wondered how the little guys worked.

Very informative. Thank you. Your example looks like it's Japanese or Chinese. Did we inherit our knowledge of artful fireworks from them? Are any American companies doing innovative things with pro fireworks?

I’ve always wondered how they make it to where it makes designed in the air like how do they know it gonna do that😭😭

Worked as a tech for over 40 years and this is the best explanation i've ever seen, short of watching a shell being built.

So i'm wondering how the squirrely lights are done?
After the explosion a small number of lights appear and they wiggle around on their way out from the main explosion

Watching this as the 4th of July firework show across the street keeps me awake! “What’s going on out there?” 😂🎉

I noticed that in this video the launch charge was very loud but at a professional fireworks show it sounds very subdued. Sometimes you can hardly hear it and I've always wondered how they are launched into the air and why it sounded that way. It sounds like a big puff of air and my guess is it's not very loud because it's down in a tube.

Im 14 years old and i always wanted to become a pyrotechnic. Thank you for this informational video!!!

Thank you so much for this explanation!! I'm from Germany and saw a few fireworks that contained hearts, absolutely loved them but kept wondering how that would be made! Interesting!! I had just assumed they would be rockets but i see why mortars are better for professional shows :o
Today I saw a show where they constricted cats and that looked so damn cool in the sky so i had to find out how that works and I'm glad i came across this explanation with examples!

what happens to the mortar shells? do they burn up? do they explode into small enough pieces?
i read through the comments and found that it is possible to find shell fragments sometimes! they come down in a zone where none of the viewers are allowed to be, only the protected crew.

do they have to be round? (to have a precise angle and speed etc probably yes, right?)

for example what would a mortar look like that shows up as a star shape in the sky? the outer shell a circle and in the front and back half more filling material and then around the midsection of the ball a star shape arranged with only the tips of the star close to the edge of the shell?

and how would one make a mortar that shows up as a round circle that changes colour twice (so three colours in one explosion)?

what makes the shrill whistling sound sometimes used?
"Great question. The whistling effects are generated by Potassium Benzoate packed into a resonator tube." thanks 👍

in another video you said the height of detonation is 100 ft per 1 inch firework thickness so in this firework does the timefuse need to be 8 inch long to achieve the 800 ft detonation? or are there different timefuse burns?? thank you for all the information you provide..

I have a question how do I become a 🧨 pyro ❓I been a huge fan of fireworks all my life. I always bought fireworks every year.Didn’t know if you want big fireworks I 👀 it cost more.Right now how can I become a pyro?

I think this was a great and informative video! I enjoy learning about how things work and have been watching Workers assembling shells. Their work is so intricate!

good

Waited years for a video like this - thank you. Is black powder simply a very refined version of gunpowder? Sulphur, charcoal, potassium nitrate, but calibrated perfectly?

Thank's man voor the clear explenation. What is de ration between de size of the shell and the blackpowder undernead the shell?

Very interesting, thankyou

What I really wanna know is how they compress those effect balls and what material they have. We all know the lift is black powder and hard salute breaks are titanium and potassium perchlorate+aluminium powder(flash) 😉

Machines do most of the wrapping these days and the insides of a shell do not look like a Christmas bauble. This is a rather basic description and really doesn't get across what shell construction is like nor how stars are made.

Great explanation but what is aluminum? Its aluminium

How does someone go about getting a license in order to be able to buy stuff like that to shoot??

Amazing! I was today year old to find out.

So how do babies get their hands on them and disturb my sleep I heard from firefighters that they can kill you 😢

Can someone teach me how to make a little one in my house? I really want to make one for our traditional ceremony which is called Chaharshanbe soori which is in the next few months

Just like in minecraft

Looks like an onion an behaves as such to. Layers after layers. 500 kg BOOM is AWESOME

Very well done. I've always wondered how these things worked.
About how high does that 8" shell go before exploding?
How much does a single 8" shell cost (on average, I realize they can vary)?
How much debris falls back to the ground? The shell casing looks very thick.

You talk about the safety aspect of the mortar shells and it reminds me of the fireworks show put on next to the Trinity River near downtown Dallas in the 1980's. We were all scattered out in the grass and the wind was blowing from the same predictable southern direction in the summer. Then halfway through the show the wind changed and started coming from the north. Shell fragments were falling into the crowd and hurting people. We got up and ran for our cars parked a short distance away because they never stopped the show. Fragments were even falling in the parking area hitting cars. Either the people putting on the show just ignored the wind change and the crowd or they just didn't care. Either way that was the last time I ever watched a fireworks show up close.

Excellent video. Great explanation. I learned something.

👏

Rice holes?

A VERY interesting video, and very informative as well sir. I really enjoyed it.👍😁✌️

Can we get the slowMo guys to film one explode from close up. (Not launching into the air but filming off a gantry 10m off the ground) and some bullet proof glass. Thanks.

Great job on this video.

How do I find a job in this industry? I would love to learn about this

No wonder fireworks are so expensive, all that handmade work that goes into making them. Amazing video 👍

Great explanation! How do you get into this industry and what type of job opportunities are available?

I knew this when I was 12! Hahahah. Great video too!

gift me some of these :(

I always wonder what happens to all the shell fragments? That stuff must come down some place right?

Cool👍

Well explained! Consider me your newest subscriber!

I've allways wondered...thanks
