Building the M-80 is a very simple to follow process. In fact the hardest part of the whole deal is obtaining the materials needed. Before you even get started with your build you will need to make flash powder which you can learn how to do below.

Making Flash Powder

Flash powder is an explosive used in all firecrackers and larger Salutes such as M-80s and Aerial Bombs. Although there are many different formulas for Flash Powder, the safest (and the industry standard) is made just from potassium perchlorate and German Aluminum. It is far superior to any other flash powder formula in many respects.

The Formula

70/30 Flash Powder:
  • Potassium Perchlorate 70%
  • Aluminum Powder (German Dark) 30%
This is the industry standard flash powder mixture found in all firecrackers and Salutes. All firework formulas are measured ONLY by weight.

Both Potassium Perchlorate & Aluminum Powder can be purchased at Skylighter.com and many other pyrotechnic shops, both online and off.

For more information on measuring and weighing, see below.

Measuring & Weighing

Here's an actual formula for a white star [as an example]:
  • Potassium Nitrate 64%
  • Antimony Sulfide 4%
  • Sulfur 18%
  • Dextrin 4%
Make things easy on yourself, there are no complex calculations necessary. To make the above formula, you would just mix 64 grams of potassium nitrate, 14 grams of antimony sulfide, 18 grams of sulfur, and 4 grams of dextrin. If you wanted to make twice as much, just double all the numbers. If you want to make half as much, just cut all the numbers in half.

Cautions

Flash powders are high energy explosive mixtures and require the utmost caution in their manufacture. Of the flash powder mixtures listed below, the only one that should be used in Salutes (exploding fireworks) is 70/30 flash powder, made from potassium perchlorate & aluminum powder.

Older flash powder mixtures containing potassium CHLORATE or SULFUR are very dangerous, very sensitive to friction and static electricity, and have been known to explode without warning.

The addition of sulfur to flash powder formulations increases the possibility of spontaneous combustion by the formation of sulfurous and sulfuric acid, and the composition's sensitivity to friction & shock. It does not increase the report sound.

Although this particular flash powder is not terribly sensitive, it will still explode with sufficient impact or friction. Never grind, pound, or subject any flash powder to friction or shock. Under the proper conditions, it may explode with devastating results.


Procedure

The two chemicals used to make flash powder. The one on the left is potassium perchlorate, a fine white powder. The other is German aluminum powder, a dust-like, dark gray powder that doesn't even really look like aluminum. Although "bright aluminum" powder can also be used in place of German aluminum, it will only work well in large Salutes with very heavy walls and thick end plugs. German aluminum will make a much more powerful flash powder that will produce a great report, even in small Salutes with thin wall tubes.

Begin by weighing out 70 grams (70%) of potassium perchlorate.

Next, you'll want to sift the potassium perchlorate through a very fine screen or strainer to break up any small lumps. There are many strainers available in kitchen supply shops and it's important to get the proper kind. The screen mesh (the size of the holes in the screen) should be much, much smaller than an ordinary window screen. You want a strainer with the finest mesh possible. You should not be able to move the individual wires that make up the screen if you try to with your fingers. Using a screen like this will defeat the purpose. Large clumps will simply move the wires and make the holes bigger allowing larger particles to go through. These type screens may cost around $2.00 to $5.00, but a good quality Stainless Steel screen with a very fine mesh (a mesh that won't slide around) will probably cost you closer to $10.00 or $12.00. You can find these types of strainers at some supermarkets, and kitchen supply stores (try your local mall).

Weigh out 30 grams (30% / 100% total) of German aluminum powder. It will not be necessary to sift the aluminum powder through a screen.

Mixing

There are many ways to safely mix flash powder. We're going to show you the two most popular. One involves shaking the two in a plastic baggie, the other involves placing the two chemicals on a sheet of paper and gently lifting opposite corners until the composition is well mixed. This second technique is normally used with more sensitive mixtures, but there are those who only feel comfortable mixing any explosive mixture this way. Personally, we use the plastic baggie technique.

Pour the two chemicals on a sheet of paper.

Pour the chemicals into a Ziploc plastic baggie, making sure not to get any powder on the bag seal. If you do, the bag will not seal properly.

Although this type of flash powder mixture isn't very sensitive to static charge, we just like to add this optional step for the hell of it. "Static Guard" is a spray that you can find in your local supermarket/grocery store in the laundry supply aisle. It works great at dissipating static charges on a variety of materials. We like to spray it on just about everything (even our clothing) for added protection. On the other hand, we've fired 8" electrical discharges from a Van deGraff electrostatic generator, directly into piles of this type Flash powder and never had an ignition. Why then, do we bother to use Static Guard? The only answer is: "why not?” It's always better to be safe, than sorry, and why not take a few extra precautions when working with high energy materials? There’s always the possibility of some weird one in a million chance of an unusual occurrence, so why not take the extra second, spend the extra $2.00 and buy some added safety insurance. So, with that said, spray some Static Guard on your Ziploc baggie.


Shake the bag well to blend the two chemicals together.

Pour the mixture out, onto a sheet of paper, and you've got a 100 gram batch of damn strong 70/30 Flash powder.


Building the M-80

Parts needed:

  • 1-3/4" Tubes & Plugs (3/4" ID, 1/8" Wall, 1-3/4" Long) (Search Google) 
  • Flash Powder 
  • "Visco" Safety Fuse (Available at local gun stores, military surplus stores, and online) 
  • Tubes and fuse are available online. At the time of this writing they were available on eBay (search for cardboard tube). If you find that they are no longer available when you read this, a quick Google search should find them.

Exploding fireworks are known as "Salutes", which include anything from a firecracker to quarter sticks. M-80s are Salutes that were originally used to simulate gunfire during military training. They were also sold in the U.S. until the Child Protection Act banned them in 1966.

Originally, M-80s were approximately 1-1/2" x 9/16" (inside) diameter cardboard tubes filled with Flash Powder. Several slightly different variations existed by different names (such as the "Silver Salute", "Block Buster", and "Ash Can"), but in general, all the devices were functionally identical.

A lot of times we get asked: "Which Salute was the strongest - a Cherry Bomb, an Ash Can or an M-80?" Since explosive power in these instances is essentially derived from the quantity of flash powder contained in the firework, the M-80 was the strongest of the bunch. At 1-1/2" long and 9/16" inside diameter, it held the greatest quantity of flash powder. Next was the familiar silver "Ash Can" at 1-1/2" long 1/2" inside diameter, and finally a Cherry Bomb who's Flash Powder chamber was about 3/4" in diameter.

Firecrackers and Cherry Bombs are Salutes that require specialized assembly techniques or equipment, so we're not going to cover them in this section. The following is how M-80s, Quarter Sticks and similar Salutes were made.

Keep in mind that assembling and even possessing such a device is illegal and considered a very serious offense unless you are licensed to do so. Exploding fireworks have caused more injuries that any other type, mainly resulting from improper use. The explosive force generated can easily remove fingers from the hand or send flying particles into the eye causing permanent blindness. As tempting as it may be to do, never light one of these and throw it. There have been many recorded cases of defective fuse causing the firework to explode someone's hand.

Assembly Procedure

The components needed for assembling an M-80: Visco Fuse (also called "Cannon Fuse", "Hobby Fuse or "Safety Fuse"), Elmer's White Glue, paper end plugs, a cardboard tube, and of course flash powder. With the exception of some old Chinese Crackers and Lady Fingers, flash powder is the only composition used in exploding fireworks… yes, even firecrackers. The M-80 shown here is made from one of our "Beefy" M-80 cardboard tubes. It’s a bit larger and thicker than the older "Classic" M-80 tubes, but we prefer it because it produces a louder report and a deeper boom. This particular tube measures 1-3/4" long x 3/4" inside diameter, with a 1/8" wall thickness. Any size tube with matching end plugs can be use for making Salutes. Simply put, the larger the tube you use, the more Flash Powder it will hold, and the larger the report will be. Just as a reference, our "Beefy" M-80 tubes hold about 8 grams of flash powder, the M-160 tubes hold about 13 grams, and the Quarter Sticks hold about 19 grams.

Using a 1/8" drill bit, a hole is drilled in the side of the casing. This is where the fuse will be installed. You can also make the Salute with the fuse coming out one end, like a stick of Dynamite. This is called "End Fusing", which we'll cover later on this page. Contrary to popular belief, there is no difference in the report if you put the fuse in the middle of the Salute or in the end. It will work the same either way.

A bead of glue is spread just around the inside of one end of the M-80 tube. This will adhere the end plug to the case.

The End Plugs used are just heavy weight paper pressed into a cup shape that fit snugly inside the tube. There are many other ways to plug the ends of the tube if commercial end plugs are not available. Some old manufacturing techniques use plaster or similar thick pastes to secure the ends. These are dangerous and should not be used. When the M-80 explodes, these solid plugs become projectiles and can blind or penetrate the skin and must be avoided. It is a misconception that end plugs must be thick for a loud report. Stick with thin, lightweight plugs that will fragment & not travel far when the firework explodes. Plugs made from pieces of tissue rolled into a ball, pressed into the end of the tube and thoroughly covered with white glue are acceptable.

The End Plug is pressed into the tube until flush with the surface. Wipe off any extra glue that might seep out when the plug is inserted.





A piece of Visco Fuse is cut, no shorter than 3", and inserted into the tube. Make sure that the fuse is unobstructed and extends all the way to the bottom of the tube.

Lay a thin bead of glue around the fuse sealing it to the case.

 


The tube is then filled 3/4 full with standard 70 / 30 flash powder. This is the only Flash Powder that should ever be used in exploding fireworks of this type. Do not fill the tube more than 3/4 full.

 
Just as was done before, run a bead of White Glue just around the inside of the tube and insert an End Plug flush with the case. Wipe off any excess that may squeeze out.

Just for looks, the case can be painted red, signifying an explosive device. There are many different types of paper tubes available that already have a colored outer wrap.

The completed M-80. Remember that these devices were banned for a reason. It is suggested that the construction of M-80's and similar devices be left to the licensed pyrotechnician. Always follow the basic fireworks theme: light fuse and get away. Never light any exploding fireworks in your hand.

  1. Hi,

    Nice and complete article definitely usable, can you tell me if it's possible to make the fuse go in one of the ends of the tube? through the plug? or is that doing damage to the power in the end.

    Thanks

  3. I just made up 10 of these today, I was extremely careful to follow all safety precautions, but still I was nervous as hell. I used the 1/16th wall tubes as I had already ordered them. All I can say is that when I tested one out it was a tremendous explosion. I placed it on the end of a 4" X 4" post in the ground and it put a large groove in it and an narrow split in it down about 6". I was impressed.

    Be very careful people.

    1. Something that was not mentioned was to use a spiral wound tube as opposed to the "convolute" or parallel wound tube,parallel wound tubes are more likely to break up into larger fragments,also Indian (comes from India) blackhead aluminum powder such as a 2 micron flake particle size and shape absolutely out performs anything like German Eckhart super.
      1.5 micron Star Molecule is awesome too.I know for a fact that the more powder in the tube,as much as you can fit the better the report and explosive damage are greater.the original military M80 Firecracker was completely filled-no air space.

      Delete
    2. India blackhead is not superior; if anything it is less powerfull than German.
      Also, spiral or convolute is not even a matter worth making an issue over; this is a small tube not some huge firework. The original M80's were filled completely but this was not a way of making them louder or more powerfull.
      Filling them completely makes for less expansion room for the blast, hence less noise.

      Delete
  4. It states do not fill the tube more than 3/4 full. Does that mean to leave the flash powder a little loose. Or press the end caps powder to pwder tight? I don't want to over look any detail.

    ReplyDelete
  5. It means to leave a bit of room for the end caps, but a greater or lesser density will obviously affect the size of the blast. You don't want very loose powder, however.

    1. actually ive done a lot of research since asking the above question as it turns out using the 100 gram speces you should end up with about 30 m80s or 4 quarter sticks or 2 half sticks or 1 full stick http://en.wikipedia.org/wiki/Salute_(pyrotechnics) the link is where i recievedmy information but please correct me if any of it is wrong.

  8. If you have made it this far and have decided to proceed and buy the materials... You are in it and breaking the law! So I highly recommend some sort of human trafficing to purchase a person to help you assemble these. It is tedious and quite menotonous should you decide to make a bit of them. LOL!!!

  9. Am new to this and all I know from doing alot of research and thinking is always use
    the 70/30 mix as listed above and dont use cheap alternitives. Buy yourself some explosion
    proof gloves its worth the money. Also I saw with my own eyes a blue aluminum in the 70/30
    mix where combined the flash does not rapidly ignite but only a slow burn. It does explode when it is confined. Also is the m-80 somewhat safe when its all put together meaning can you shake
    it to death or do you still have to handle with extreme caution. Thanks

    ReplyDelete
    Replies
    1. Yes, this formula is fairly stable. It will not explode without heat, impact or a sufficient amount of friction. Shaking it to death as you put it won't be enough to explode it. Anyway, why take the chance? Treat them with respect, and have respect for your own safety (and the safety of others).

      Also, NEVER use any other formula such as those that call for potassium chlorate or sulfur. Read Cautions at the beginning of the article.

    1. My advice is don't waste your time trying to make the salutes out of black powder. I promise you will be disappointed.
      Flash Powder is not only easier to make,just as stable( I would say more so) and is much more potent.start out with 70/30:Potassium perchlorate -325mesh and 2 micron Indian blackhead,buy the perchlorate with cab-o-sil (fumed silica)or add your own to the mix, this also I think really adds to the power.

      Delete
    2. Flash powder explodes much more easily than black powder!!! I don't know where the above writer gets his info! Sure, you can make them with black powder, they will however be less potent and thus less loud. Home made black powder is not a great way to go as it is not potent enough. Factory made will give you a decent blast but not as good as flash powder.

  14. Just finished making 30 M80s and 14 M1000s with this recipe. I made 800 grams of flash powder without any incidents and tested a M80. Very loud and powerful. It was scary at first but after making the first 100g batch it just got easier. One tip I have is to toto cannonfuse.com and you can buy the tubes, plugs, and vico fuses for a great price and fast delivery. Also I bought the potassium perchlorate with cab-o-sil and the aluminum from American Pyrotechnics Supply (amazon 3rd party vendor)

    ReplyDelete
  15. After reading this post some time ago I decided to try it for myself. I was a little nervous mixing the flash powder but in the end the tension eased. I did not have any cardboard tubes so I substituted 1 inch plastic PVC pipe. I drilled the fuse hole and secured the cannon fuse into the side at midpoint. I made this particular salute about four inches long. I cemented a PVC cap on each end. I was a bit concerned the plastic would shatter into dangerous schrapnel so I placed it behind a shed and lit the 10 inch fuse. SON-OF-A-BITCH!!! It was louder than any commercial firework that I have ever heard/seen.

    BE VERY CAREFUL.................!!!!!!!!!!

    ReplyDelete
  24. Two questions.

    1. Convaluted or spiral tubes work best.

    2. Most of the commercial 1/2 sticks I've dealt with use CONSIDERABLY less flash. Does the degradation need space to emit the gasses to creat a greater effect? I can't theroreticaly see an advantage to fully filling the tubes other than a fireball effect at combustion. Please correct me if I'm wrong. I'm an amature at pyro.and just seeking info.

  29. hi mate how would i go about doing the end fuse like the ones they use on dynimate sticks instead of doing it thru the side?

    ReplyDelete
    Replies
    1. One way that I've done it is to use an awl and punch a hole thru the end plug (die stamped thick glued brown Kraft paper) of whatever size salute you are making, then use white glue or hide glue to plug the end wipe off excess glue.the fuse should be set about 1/2" into the tube and fused well with hide glue.
      or if you choose you could fill the end cavity with a thick layer of hot melt glue which really makes the fuse firmly a part of the salute and if done correctly can make a really nice looking salute, the drawback is that the hot glued end plugs could become high speed solid projectiles.
      the hot glue method makes for a fast and great way to make a salute but as I get older and my children are growing up I've been leaning more into making salutes with only Kraft end plugs with a combination of two different glues so that you get the exact same power but no projectiles the whole salute is blown to tiny paper fragments and is just as potent.

  30. Question: Why do you recommend mixing in a plastic bag, when we all know that plastic is known to be very capable of generating static electricity? Why not mix in a paper bag instead? But, if you know from personal experience that a ziploc bag is safe, do you recommend spraying only the outside with static guard spray? If static on the bag could be a concern while mixing; couldn't the inside of the bag create static also?

    ReplyDelete
    Replies
    1. First of all you raised a good point about why use a ziplock bag because of it's static properties.
      I am very familiar with this type of flash (70/30 perc./al)I have mixed as much as 500gr at a time in glass mason jars (glass jars are virtually static inert but i still spray the outside of the jar with static gaurd.This flash mixture is safe to mix and store if necessary.Do what you want as far as mixing it is concerned this flash is very stable and I do know from years of mixing pounds and pounds of this stuff (I don't often mix a pound at a time but I have done it when making quantities of larger salutes.There are some good pyrotechnic supply dealers on the net that you can get great perc. and the best al.Look for Indian blackhead 2 micron and also star molecule 1.5 micron and you want -325 mesh domestic milled potassium perchlorat (Chinese is cheaper and I have not used it myself the fact is that it's not a bad product but it does not potentiate the blast wave quite as much as domestic milled -325 mesh,it's not a bad idea to get the Perc. with .3 % cab-o-sil to keep the flash free flowing and loose.

  45. I used to buy these many years ago in my younger days so I don't really feel as if I am doing anything overly illegal. I did want to share a mixing hint that I feel is just as safe if not moreso than ziplock bag. I take a plastic bottle with plastic top and attach broom handle to top using elmers. This way I am a good distance away from mix and it is not in my hands. Spraying with anti static is a good idea also.

  51. So everyone is in agreement then. Being careful about the whole situation is the only way to behave..safety safety first, and im loving the broomstick idea. what about broomstick glued to folded paper, so as to pour the mixture in the tube. Or just broomstick for everything. Distance from said explosives would be key, so maybe you could get an extendable hand like the old terminator claw toys for the whole procedure. But seriously how stable is this stuff? If you drop an m80 off the second floor would it explode? what if you ran it over with a car or a steamroller? What if your dog starting chewing thru it?

  52. When I was a kid I made a firecracker out of smokeless shotgun powder and I crushed up one of those oxygen sticks used for the solid oxygen welders with the little propane tank.....don't think there available any more. anyway I mixed the two together, crimped the end of a 9 inch x2.5 inch aluminum pipe with a 2 foot visco /blackcat fuse/detonator. filled it up3/4, stuffed some newspaper, crimped other end. Went to the river and threw it into wet river mud. It made a double concussion explosion that left a 3x2 crater . It was f.....g loud!

  53. I made a batch of the 70/30's and have had 3 go off with an enormous BANG and I have had the rest just burn really bright and smoke with a poof of sound? What might be my issue? I have them 3/4 full and glued in end caps?

    1. Ammonium perchlorate + aluminum mixtures are usually used as solid fuel propellants in modern booster rockets. The booster rockets on the space shuttle are strap-on rockets fueled by this mixture.

    2. I forgot to mention that the mixture would not be as sensitive. You would need to add magnesium for more of a boom.
