A pound is equivalent to 454grams . There are 7,000 grains in a pound ; so , a grain is --- 454/7000 = about .0649 grams . An M-80 should therefore have 80 grains of flash powder --- 80x(.0649)=5.192 grams . A half stick should have 500 grains --- 500x(.0649)=32.45 grams of flash . A full stick should have a 1000 grains --- 1000x(.0649)= 64.9 grams of flash . Then as far as the salute goes it depends on the type of flash powder used . I will not go into formulation because the youtube police probably would block it if I tried ; but , it involves potassium perchlorate , dark aluminum and a sensitizer . Anyway , if the aluminum powder is fine enough flake , 80 grains of the flash powder formulated will be louder than the half stick in this video. That half stick in the video is not bad for standard 70/30 mix . The flash formulation I am talking about can be found on the PyroData site .
So, at 23 grams, I am somewhere in the middle of a quarter and a half stick. I knew I was way more than a quarter. It is definitely potassium perc and aluminum powder.
@@shavontea00 Thanks . The M-80 was originally supposed to be a military simulator for explosions in military training but people liked them as fireworks . The grain as a measurement is how they measure how much propellant is used in a fire arm round . For example , a 22 short originally contained 4 grains of black powder . The modern 22 short uses about 2 to 3 grains of smokeless powder . I also agree with you that a you tube video does not do justice to how loud a flash powder explosion is in person . A you tube video kind of muffles the sound whereas in person a flash powder explosion kind of startles you even if you are ready for it .
I was unaware of what a half stick, quarter stick were. you said a half is 23G so a quarter would be half of that, correct ? is there official measurements for this somewhere ?
@@weytogoman I know that, I make all the sizes. Some folks say an m80 is 3, others 5. An m80 is 3 and an ashcan is 5. I have heard people say that a quarter stick is 20, 25, 15. And it's really not about the size of the tube either, like if quarter stick is 20g let's say and it's in a tube that's 1 inch by 2 1/2 inches it would still be a quarter stick if it was in a 3/4 by 3 1/2 inch tube. Idk . . . It's just confusing the ATf website has some info and so do some pyro sites but they are all different. IDK man 😂
@@weytogoman oh I believe you and I knew you were correct and I like when folks tell me first hand experience because I wasn't born yet. I just want to replicate the true size is all, I was just venting a bit. Thanks 👍
It’s called a salute , cannon cracker , Dego bombs. 1/4 stick? 1/2 stick? Compared to what? Dynamite. 2 very different categories Those are filled with “flash powder” and dynamite used nitroglycerin, sodium, sorbents. Dynamite is used for blasting hard rock tree stumps on my aunts farm and it has a slower explosive effect to move “material” compared to Flash Powder aka 70/30that does not need to be contained to explode faster than she speed of sound and is very dangerous and unstable even in a controlled static free environment. Don’t get me wrong I love the “thumps” but when people don’t know the differences between the 2 people start rumors when they are naive and not properly educated. I’ve been doing stuff like that for 42 years legally under a fireworks company and I mad them for inserts in big shells , I was a flash man in a shed for a very well known Italian fireworks manufacturer. I could not wear anything nylon, all cotton, no metal on anything you wear while manufacturing, I couldn’t even a transistor radio to listen to , I would yell to my other “flash man” coworker and he was about 50 feet in the second “flash shed” so we kept the day “green” and not going crazy knowing ANYTIME Murphy will come knocking and you don’t want to answer the shed door. It was very nerve racking job because if something did happen you would NEVER know what happened……☠️☠️☠️ For extra safety precautions I put a grounding pole in the shed driven into (always wet dirt floor about 2 feet down and hooked up a body worn ground strap to dissipate any static electricity, the last safety precaution I took was to mount a 12in x 12in Brass plate just outside the sheds door so I could touch it and get de-energized from any static before I even stepped in to that 8ft x 8ft coffin. Be safe and stay green…!
If making small batches of flash indoors could you wear a strap like you described and ground yourself the same way ? when I have done it I never made more than 10g at a time. I didn't know you were supposed to wear cotton clothing either, thank you.
Ha ha, same feelings. Anytime someone says a stick, it just makes me laugh. A stick of what? Our Dynamite was about half c4. I don't even think it had 5% tnt. The sticks were weaker, slower, but safer. The mining sticks had about all waterproof Anfo. It's about 2 feet long. The loudest salute was a cylinder shell with wadding and sealed ends. It gave it a little time to expand before it hit the plugs. It sounded like Artillery airburst. That's a big stick.
I never understood creating a measuring system of comparison. Flash and dinomite are such different feelings and sounds. The pitch is entirely different and the Shockwave from high explosives are very intense. I have spent more time with dinomite, although I prefer flash. . We used to shoot 22s at it at the mine growing up. If you made a tetrazol or even tannerite to some degree is closer. One's a boom with a soft pressure change, and the other is a Crack with a powerful Shockwave. Just call it what it is. 20 grams of flash, ect.
So a quarter is about 12 grams and a half is 23 ish . . . I have been calling my half sticks quarter sticks. I hear different sizes and amounts all over . . . What is the official numbers? It's confusing 😂
Haha I used to have a bunch of those, I filled them with some rice hulls, they only had around 26-30 grams of flash but still echoed for a couple miles in the fields
I never went by the various monikers, but only by the flash composition and quantity. I prefer Shimizu No. 1(Potassium perchlorate 64 Aluminium 23 Sulfur 13) I won't use chlorate anymore after a near catastrophe that occurred while using all pyro safety protocols; chlorate isn't necessary.
Does anyone know what states sell fireworks year round? Looking on the net, it's not real clear. I know south Dakota does but I have no clue what other states.
@@shavontea00 yeah, I bet you're right. I was hoping to find a place closer to Texas. Per the internet it like maybe new Mexico but it's just not clear.
Just start looking for the known shops. Phantom, big fireworks, whatever store name you can think of. Most are gonna have shops in the more pyro friendly states open all year. Then Google the shop name along with whatever state you prefer and find out the hours. Most Michigan shops are open year round though.
Indiana is a great state for year round fireworks. They have deals out of season too. It’s funny I’ve lived in Chicago my whole life and Illinois has tough laws on fireworks. Sparklers and little smoke bombs are all you can buy in Illinois. But right across the border into Indiana… holy smokes! There are about 30 fireworks stores. Warehouses I should say. It’s hilarious how all the Illinois residents drive to Indiana for fireworks. It’s like 20 minutes away without the traffic jams.
I don't know where this "stick" nonsense comes from. There's no comparison of flash powder to Dynamite. Dynamite is nitroglycerin. And flash powder is powder. Flash will not break rock, will not cut steel.
@@joedirt7604 Good one. They should be compared with other flash powder devices. (powder weight comparison) When people make the 1/4 or 1/2 stick comparison it make others believe that it is in fact as powerful as dynamite. In reality it's not even close.
@@coppersworld2054 well a firecracker is what pops into my head when you say flash powder. Im sure other consumer products use it but Since I dont make anything I cant give you a list. As an average joe the only example of flash powder that comes to mind is a regular firecracker from a fireworks tent. I feel that title could be misleading as well since a firecracker is a lot smaller.
This comparison to dynamite is complete bull. I know, ppl have been using these half and quarter stick terms forever but it’s complete nonsense. Just to put it in comparison, an M-80 is comparable to a blasting cap, which is used to detonate the dynamite. A quarter of a stick of actual dynamite is around 60X faster in detonation speed than whatever sized tube filled with flash powder your comparing it to. We’re comparing low explosives to high explosives. They’re still cool, don’t get me wrong 👍
@@theprimeministerofchlorofo7546 Yes, it goes back as far as I can remember in the 70’s, and probably a lot further. Didn’t mean to come off as a d**k, sorry
To qualify as a half stick salute, you need at least 25 grams of 70/30. These I have weighed myself. 23 grams is closer to a Half than a Quarter Stick. Yes, technically mine would still be a Quarter because I'm 2 grams shy. Quarter stick salute is 15 grams. An M1000 or Full is anywhere from 50 to 100 grams. You can find these numbers on Wiki which cites Journal of Pyrotechnics by Kosanke. The more powder content you have, the wider the tube diameter you need to avoid unignited powder. Those 110 gramers you got would have to be at least 2 inch diameter or more I imagine. More than 25 grams in a 1" diameter tube is just wasted powder. So really, your 60 gram stick is actually a full stick so long as you have a wide enough diameter to ignite all 60 grams the tube breaks.
Adding anymore flash is wasted. If you look at the ground where you lite the salute and see any flash powder remains. Since flash burn so fast, too much powder most of it won’t burn. Adding more flash you have to go from 1 inch tube to 2 inch tubes. The best mix for me is potassium Persulfate, sulfur and Mag powder. 20 grams sounds like 100 grams of 70/30 mix Potassium perchlorate and Dark aluminum powder.
