Pyrotechnician here. I'm surprised you didn't cover the process of rolling stars, which is imo the most fascinating part of making shells. You roll the core of stars in a cement-mixer, spray them with water and sprinkle some starmix on to them. As you repeat this many times they become larger just like a snowball. You roll in layers, which mean you can make color-changing stars by just applying different colors in each layer. Time-consuming but very satisfying.

[@RozzerMildred97]

Also well worth the end product. Some of the ghost shells you see are just magnificent!

[@WS12658]

Sorry if I'm being ignorant, but what's brave about flying a drone through fireworks?

[@glaza4957]

The reason why copper can produce green and blue colors depending on the environment is that copper ions can exist as cuprous (Cu+) and cupric ions (Cu2+). Cuprous ions produce blue flame color, while cupric ions produce a green one in the presence of halide ions. When a flame contains reducing agents in excess (e.g. candle flame or burning alcohol), then the cupric ions get reduced to Cu+, so the flame will turn from green to blue. As the cuprous salts are generally not stable, blue fireworks usually contain Cu2+ salts and the rest of the mixture is made to have a strong reducing environment (fuel excess), so the cuprous ions are formed in situ during the combustion.

[@Boredom_Herself]

Nice, this is something I never knew! Thanks!

[@Raz.C]

@@raed.gilani Coincidentally, I had a similar question to this one appear on my grade 12 final exam (for chemistry). However, the answer was never part of the course material and the question was asked to test our ability to think about the behaviour of atoms/ molecules, without regurgitating quotes from a textbook. My final results were good enough to guarantee me a place in the university of my choice. I ended up doing a BSc with a double major in organic chemistry, as my first degree. I tells ya, the world around us and the universe around it, make so much more sense when you understand chemistry. It gives you the grounding needed to understand how, when and why an atom/ molecule will or won't react with its environment. You understand how "life" is just a series of self-sustaining biochemical reactions and you can see how inanimate matter can easily become living tissues, through entirely natural processes. That's not to say that studying university-level chemistry WILL turn you into an atheist. It WILL show you matter can form from energy, how life can come from non-life and how evolution works on a molecular level. In other words, you'll learn how everything in the universe works and how it was formed and none of those answers are ever "God did it." They are all answers that you can test for yourself in a lab, seeing the truth for yourself. It doesn't teach that God doesn't exist, rather it shows you how God isn't necessary, isn't needed for anything that exists.

[@MikeKayK]

​​​​​​​​​@@raed.gilani he won't be able to understand, yet you were "lucky" enough to be born into a Muslim family, which is the one and only reason you believe what you do. This coincidence is the only reason you are privileged enough to "know the truth" while everyone who was unlucky and not born into a Muslim family got screwed. Right? Yeah. I know. Brainwashing is real. Just have to start early. It's all good, I know that no amount of logic and common sense can snap you out of it at this point. Christians are right, Jews are right, Muslims, Buddhists, and the thousands of other religions are all correct! And all the gods of every religion apparently exist, too! Isn't it amazing? Except the poor saps who were born into secular families all got screwed and are going to hell I guess. Hey--keep on believing bro, whatever makes you happy. Just chill with that high and mighty ego you got going on there.

[@Max_G4]

Well, the video showed that those parts do work separately. Sulfur is often found in volcanos, so it would be like "Hey, this rock is from the big fire mountain, maybe it will improve our fires" and it did. For the potassium nitrate, I don't really have a guess, but it's not literally bat poop but a solution which then dried up and just experimentation. At some point they would try to disperse it more and wood can't take it in, so they took the most flammable liquid they had and it worked well enough. Keep in mind that this process happened over centuries of people trying out different things and passing on the knowledge to future generations. And that is kind of the beauty of science. It's a lot of (semi-informed) trial and error and the good ideas are then passed on and used as new reference points years or decades later.

[@SpicyNuggets402]

Blue and purple are the hardest colors to achieve due to their temperature needs, which Derek saw first hand trying to use the sprays. As someone who's worked with fireworks for 15+ years now, it's great to see a video like this be spread to the masses.

[@garycard1456]

There is the Veline system/formula, which enables one to make, for example, aqua, lime green, tuquoise, chartreuse, etc, colours.

[@galfisk]

The Veline blue is quite washed out, but as a starter kit, it's all right. You can make a base for all colors (though the green is a bit special) and just add the desired colorant(s). It has dextrin so you can use water as a solvent, but I liked using acetone to dissolve the parlon better. I've heard that xylene is even better and doesn't produce the springy, sticky chewing gum-like texture that acetone does before it dries.

[@supernatural_forces]

Don't be such a fan of someone or metaphysical explanations which makes you forget more important issues such as Purpose of Life/ Reason for Creation which are perhaps more important for most humans. First thing which has to be considered is - There has to be One Absolute Truth/ Objective Reality (100%) [regardless of what different scientists, ph.ds, doctors, philosophers, societies, religions, cultures, individuals, etcetera believe]. The rest could be either some Truth with some Falsehood mix in it (no matter in whatever ratio/ percentage it is in) or Complete Falsehood/ Delusion (100% Wrong). And, its something like this -: If Analogy is to be used our Body is like a Hardware of the Computer and our Soul is like a Software. Just as Computer's Hardware is Useless without a Software, similarly, a Body is also Useless /Lifeless without a Soul. We go through 5 Phases in our Life :- 1. The Realm (outside of this material Universe) where we took an oath & chose to be granted free will (The Testimony of believing in Only One God by our soul), 2. In our mother's womb (9 months) - The soul is breathed into the body, which gets created from a single molecule through a unique DNA🧬 (An Instruction Manual/ A Program/ Code) fashioned/ programmed by Creator. And, as the soul enters a body that's from where our consciousness and conscience comes (it happens with a lightning speed i.e. in a fraction of a second which Scientists/ Doctors couldn't able to capture it), 3. On Earth 🌎 (On an average of about 60-70 years) [Commencement of Test with the development of conscience], 4. In the Grave (The time frame from our death till the Day of Judgment/ Resurrection) & 5. In Paradise or Hell (Eternal Life). All are Temporary except after the Resurrection. So, the consciousness in brain 🧠 gets activated when soul enters the body & through soul the conscience (sense of right and wrong) of heart gets activated (including feelings like joy, pain, anger, etc.).

I loved this one. My wife and I are both rocket propulsion engineers, a socially acceptable career for the pyromaniac. Three years ago, we visited great nieces and nephews in Tennessee for the Fourth of July, and witnessed the greatest fireworks display we had ever seen (beating even the 1976 bicentennial displays) in our great nephew's field. At the end, I turned to my wife and said "We are so retiring here." Those fireworks are legal, and available year-round. Last year, we bought our Tennessee farm, and are looking forward to blowing sh*t up throughout our golden years.

[@devonscotttaylor]

It surprises me how effective and mesmerizing those drone shots were given how simple the footage was itself. Not to downplay pyrotechnics nor expert level drone piloting, a black backdrop and soaring balls of fire viewed from a flying perspective seems like something that wouldn't be too difficult to render. Yet, the result feels like something special and nothing like your run of the mill CGI effects. Amazing shots, truly. Great vid! 👌🎆

[@hieronymusbutts7349]

Stochastic randomness in chaotic representations become exponentially harder to accurately render with complexity. In other words, every little spark has a probability of what direction it's going to go in, what kind of resistance it's going to meet, what kind of temperature differential it will encounter, all of which very subtly changes its progression. Now multiply that by millions of sparks and smoke particles interacting with ambient weather, and you start to get an idea of the raw complexity of the mechanics involved in simulating even such a "simple" rendering perspective. You have to choose a level of granularity as a limit, otherwise you could get into progressively more miniscule details until your attempts at rendering a basic scene becomes an attempt at a physics engine capable of simulating an entire universe.

[@devonscotttaylor]

@@hieronymusbutts7349 I must admit, I did bite my tongue a little on that one. I appreciate the detailed explanation! If I understand you, I imagine the difference between the drone footage and a rendering can be comparable to replicating the resolution of film digitally. The deeper you look, the more intricate it gets.

[@devonscotttaylor]

@@hieronymusbutts7349 Also, out of curiosity, when do you think CGI will be indistinguishable from our visual perception? Assuming you believe it's a possibility of course. If not, how come?

[@hieronymusbutts7349]

@@devonscotttaylor I think we already have CGI that can be indistinguishable from our visual perception, though it's much harder to have *animated* CGI that conforms as much. I think it's likely in our lifetimes, but the limitations will largely be: A) hardware capable of highly discrete information clusters (compare, say, a Lite-Brite to a CRT screen to an LCD) - if you can't display the information, it doesn't matter how rich the information is. And if you blow it up big enough, or get close enough to the source, you start to see those individual nodes in a way humans generally need a microscope to accomplish. B) cost effectiveness - most things just won't need that type of hyper-realistic rendering, and it'll likely always be an expensive and time consuming process to create those massive amounts of data points interacting with each other. Any physics engine take shortcuts just to reduce the raw amount of variables so it can actually compute things, otherwise you can add variables all the way down until you're trying to approximate quantum fluctuations as the basis of everything. It's one of those "assume a perfectly spherical cow with zero friction" scenarios, where just trying to calculate the dimensions of a single variable is so intensive that you have to assume absolute values outside of it to actually make the calculations work. Now make it that every variable changes in relation to every other variable, and it's hard to create a system that can even function without error, much less one that represents accurate physics and optics. tl;dr there's a lot of moving parts to synthesise a moving image and it gets more complicated and expensive the more moving parts you add to make that image more realistic. We can do it, but most applications don't need it, so we trade complexity for cost-saving and "good enough" metrics.

[@devonscotttaylor]

@@hieronymusbutts7349 Interesting. As far as I understand, quantum computers have advanced quite a bit in the last few years and are still nowhere near having the ability to operate common computing. I'm aware that replacing binary isn't the objective of developing quantum computers; however, do you think that could be the case in the next ~50 years? If so, I bet the graphics capabilities would be off the charts. Ps. just to clarify, I meant animated CGI in my previous question. Thanks for your response!

LOVED this video! Was like Deja Vu! I went through all of this about 5 years ago when I started making my own fireworks and rocket engines! From homemade black powder to r-candy, right down to flying FPV quadcopters through fireworks! My favorite pyrotechnic mix is currently sulfur-zinc flash powder! MUCH easier to make and is non-hydroscopic so easier to store as well! You can also change the deflagration rate! I currently use it to make projectiles for my homemade rocket launcher! Come try it sometime! ;-)

[@TheTechAdmin]

11:50 In middle school, my parents allowed my friends and I load artillery shell fireworks during 4th of July. One of my friends loaded the shell in upsidedown by accident. Instead of the THUMP sound you hear when it gets launched into the air, we heard a little PoP, and saw a foundation of sparks pouring out of the mortar. I knew right away what had happened 😮 and I yelled, "RRRRUNN!!!" We all scattered as fast as we could. When it exploded, it felt like a major league pitcher threw a handful of hot sand and rice at your back. No one got hurt, thank goodness.

[@pyr0duck676]

The reason you are getting green and not blue with your copper test at 23:03 is because your flame was actually too hot. Copper compounds need a cooler flame to get the blue color. At 23:23, your flame is cooling down and can now turn blue. If you do your same flame spray test with a little water in your solution to cool the flame temperature down, you will get the blue color.

[@cptkirkpyro5656]

copper burns a patina green always has and always will.... and it burns that color due to the formation of copper oxide...

[@pyr0duck676]

@@cptkirkpyro5656 Not quite. Copper flames will typically turn green when CuOH forms in the flame. However, copper will burn vibrantly blue if you reduce the amount of CuOH and increase the amount of CuCl/CuO. There are quite a few papers that describe this phenomenon and why copper flames can change colors depending on the circumstances.

[@chriskennedy2846]

@@pyr0duck676 Have there been separate tests first isolating the burning of CuCl, then burning the CuO? Would each be blue individually? If so, I guess we can't blame it on changing the oxidation state from Cu+1 to Cu+2.

I used to enjoy watching fireworks and also lighting them up, until when I saw a whole tree burn down at my backyard on the festival evening. It was home to 3 birds and 2 squirrels, and I had literally spent hours watching them. It caught fire when one of my neighbor's fireworks hit it that day. I was heartbroken and couldn't save anyone from that event. I believe that fireworks are fine with limited use, that too in controlled environments, away from birds and animals.
