Yes...until he says one word.....when he says the word it drives me nuts . He says it wrong and for some reason it annoys me badly. He is brilliant otherwise. Chocolate....not pronounced with the "ahh " sound. It's not chaah-klat.
It's strange to see plastic parts period! I believe most of the European makers still use paper casings. Perhaps this is just one country. The Japanese fireworks are incredible though. Probably the best in the world.
@@liliangomes7658 Yes, there is. It's called Bioplastic. There are two main types of bioplastics--PLA and PHA. PLA (polylactic acid) is typically made from the sugars in corn starch, cassava, or sugarcane. It is biodegradable, carbon-neutral, and edible. PHA (polyhydroxyalkanoate) is made by microorganisms, sometimes genetically engineered, that produce plastic from organic materials.
@@liliangomes7658 You can clearly see this is like a wax plastic is characteristic of biodegradable plastics. Also the Japanese fireworks compared to this, is like comparing a grenade from 1900's to modern grenade. Just saying. They care only for tradition. They don't have the best fireworks in world, not even close. They literally spend an entire year building the largest bomb filled with the most explosives, weighing the most. Its like saying a cannon can achieve more than a modern artillery piece.
The subject matter, Brooks Moore's narrative voice, and the wonky but subtle background music all combine to create just the best form of chill, comfortable viewing.
So much work into these things. It is unbelievable the work and money and time it takes for a DAILY show like at a place like Disney's Magic Kingdom, where it's a 20 minute show. That is a full time operation with SO MANY people building pyros...
Hahaha!! Yes, I do too! I've wondered if I was the only one. I love the show, but it is also very soothing. I'll put it on to listen to when trying to go to sleep at night, not just for naps.
This video gives you a pretty good idea, but it's certainly missing a lot of detail. Shells come in all shapes and sizes. Usually plastic but sometimes multiple layers of paper mache. Most shells are spheres which is just a single compartment. Black powder is the most common propellant and it is very difficult to ignite with static. Aluminum flash powder on the other hand is the dangerous one. Flash powder is used for bombs or "salutes", and sometimes included as a separate charge like the comets in this video. We call this a "bottomshot", because it makes a loud bang a few seconds after the main shell goes off. Black powder burns slowly, which expands and blows the shell apart. Flash powder "defragulates" which means it explodes faster than the speed of sound (nothing can burn faster than sound). Also, all of the fuses use black powder. Quickmatch is the entry fuse, it burns faster because it has space for the gas to expand which is why it looks kinda loose. E-match, or electronic ignition is much more expensive and complicated to setup than quickmatch, but it can be timed a bit more precisely. Typical homemade shells tape a paper cup of black powder to the bottom as a lift charge. This also ignites the timefuse at the bottom of the shell.
@@mikebrickner1701 they really shouldn't be worried about static on this firework, it's possible but extremely unlikely. Even so, black powder burns so slowly that you might get burned but it doesn't create a shockwave. In fact, it's so slow that they stick a cup of it under the plastic shell and it launches the shell hundreds of feet without breaking it. It only breaks when the black powder inside the shell tries to expand/blow it apart. If you watch anyone build a homemade firework, you won't see anti-static gloves. If we're dealing with aluminum flash powder you'll typically see it get "diapered" where we combine the chemicals on a sheet of paper and roll it back and forth. We do not mix flash powder in a ball mill because it's sensitive to heat, friction, and static. Just a few grams of flash powder will explode a pumpkin, from experience. The biggest salute I've fired was 1KG of flash powder.
Another fun fact, the black powder inside the shell burns so slowly that it ignites the "stars" when it goes off. When the shell is sealed up, it needs to be very compact inside so the black powder can push hard enough to blow apart the shell. It also needs to be very tightly sealed so that the shell blows up into pieces instead of two halves.
@@mikebrickner1701 Sort of the opposite. As long as the metal tools are correctly grounded i.e. in the hand of someone wearing anti-static gloves that are also correctly grounded, they won't build up any charge. Less conductive materials like rubber for example, do. This is why rubber balloons make for a good demonstration of static electricity.
@@gibbogibbogibbo Pop quiz time! Question 1: What is the maximum speed that a flame can propagate? A. The speed of light. B. As fast as the molecules can bump into each other. C. As fast as the original source of the flame. It's obviously B, flame is a chemical reaction and the flame front is molecules bumping into each other to transfer heat. Now how fast is the speed of sound? Same answer, as fast as the molecules can bump into each other. Why does that matter? Doesn't every explosion create a flame? Not quite, high explosives are decomposed almost instantaneously by a supersonic shock wave passing through the material. Supersonic literally meaning faster than sound. Nitroglycerin for example already has the oxygen inside it, so it doesn't really burn using oxygen from the air, but instead rearranges itself and releases energy.
Its not bad at all, if it was so dangerous, they wouldn't ship it by the tones by truck, and then I watch the handlers throw them back n forth literally dropping them occasionally. If it explodes its gonna be due to static only, so static tap and paper is good. Otherwise we all blow up when throwing it in the buggy at the store.
Fireworks are a lot of fun! I have an app on my iPad where all you have to do is tap anywhere on the screen, and let the show begin. There are some cool effects the fireworks have on the app too
I think how do they do it showed this! It also talked about how the roofs of the buildings they assemble fireworks in aren’t connected to the walls, to minimize damage by letting the explosion go upwards rather than out.
Explosives detonate, with gunpowder we talk about deflagration… A fast combustion🤷🏼♂️ Gunpowder Can light by friction, and start burning…. Yeah a firecracker explodes, But still its deflagration😎 Lovely video💯‼️ Im not a pyrotechnician - Im an explosives expert!🤓
"The pyrotechnician must handle them gingerly, or they could detonate." At that point I found myself counting his fingers to make sure they were all there...
Fun fact, if you see a firework that is either purple or blue, those were the hardest to make out of any of the other fireworks that you see, it's because it takes 19 chemical agents to get the right color.
@@kataraarts3027 unfortunately that isn't how it works. Different chemicals are color donors and need other elements present in the reaction to give off the correct wavelength of light along with all of the other properties needed to create a firework star that will stay lit at a few hundred feet a second velocity.
"What's a 4th of July celebration without fireworks?" A fucking quiet night of sleep! People do this all the time in the city even though it's illegal. Every. Single. Year.
The people who work making these massive fireworks have serious balls of steel; to think that they are working around so much explosives, any incidents could be fatal
@@AhDollar wild creepers are actually indigenous to northern Mexico, southwest US and Mediterranean regions where it's warm and dry so you won't have luck in Canada
How much does that shell shown, co$t? As a teen, after a fireworks display, I found an unexploded 8-inch Star Burst shell. Took it apart and found rice inside. What does the rice do? Thank you.
lol you should see how they're made in China. No plastic casings- it's all paper and skilled labor. Ball shells are even more labor intensive than this, same for cakes, fountains, roman candles etc. The latter is loaded by hand one shot at a time!
