I tried to make actual dust explosions inside of large plastic bags for this video but it was too hard to make go off reliable so I decide to just make huge fireballs instead :D We have good stuff coming on end of the year, couple larger build projects are ready soon and we will finally also get some outdoor chronos ring videos ready soon
Try adding pure oxygen to the bags
Was it plywood with glue in it? A nice resinous pine would be more flammable. Powdered herbs would be good, too. Eucalyptus leaves or mint, bayleaf (laurel), rosemary, sage or lavender. The essential oils are very combustible.
So- did you have fun pumping your custard? :D
*what the hell I'm going on about->

Yes. I posted this just for the rude part.
I would love to see how explosive magnesium powder would be!!! 😱
Also maybe titanium powder!
I've heard good results have been achieved when saltpeter, sulphur and charcoal are mixed together.
Just get the right proportions.
Some have used saltpeter and diesel fuel, I don't know how well it really works as not tested myself but both are available at farm supplies esily so it would be easy to test. There's various flavours of the saltpeter available, you need to get the right one for it to work as the oxygen supply, sorry don't know the correct term in English. Kinda off topic as it's not powder but it should explode anyway. Much easier to make than real black powder as you only need to wet the saltpeter with diesel but obviously not usable for guns. Gasoline would be easier to ignite but much too dangerous just because of that
Black powder!
Same with potassium nitrate and a couple of basic additions
Yeah, or if you get some ammo (what kind and caliber doesn't matter) and get that akward powder out of them. That stuff is a mean dust.
The creamer fire you're thinking of is with non-dairy creamer. It's usually based on vegetable oil, hence why it burns so well; it's basically powdered oil.
It is very dangerous so don’t try this at home😊
But it is fun! So maybe try it. But if you burn down your house don’t blame me.
Non-dairy creamer fires can be TERRIFYING. You'll want to be far away if you test that. Just look at this clip from Mythbusters: ruclips.net/video/yRw4ZRqmxOc/видео.html
@@theawesomer
If somebody tests this indoors they will suddenly be homeless... or dead.
Not good!
I wonder how much more dangerous it would be mixed with cinnamon..... which is little more than dried tasty tree bark.
Creamer is fat and sugar so....🔥🔥🔥🔥🔥
When I was younger, the largest grain elevator in my area exploded when an insufficiently lubricated conveyor bearing ignited the grain dust. Shattered 2 foot thick reinforced concrete walls like glass. I was 20 miles away at work, and the blast shook the building HARD. Lots of broken windows that day. You could smell burning wheat for weeks after.
I was about 6 miles from a grain elevator explosion near New Orleans, about half of the building was reduced to rubble, houses shook for miles around, pieces of lighter weight debris fell in out neighborhood. Much more energy than you might expect from a grain dust explosion.
Damn
I like the fact that in Finland the neighbours probably just thought you were setting up the pyro for a metal concert.
"metal" concert 🤣
Titanium dust is one of the worst dusts. I used to work at a place manufacturing jet engine parts and there where a lot of regulations of how to design the exhaust in the welding cells to avoid burning titanium dust.
It's also really pretty, with intense, silvery white sparks. You can get it from pyro chemical suppliers.
SR71?
@@darioinfini If your spyplane is made of dust ur doin somethin wrong
@@moritamikamikara3879 You could generate a lot of dust from making your spy plane though.
The explosibility of titanium dust is so high it can't even be measured. When they aerosolize nanofine titanium powder into the explosion chamber it just spontaneously combusts.
How about coal dust? Some of the largest mine explosions were due to coal dust
I will get that also on part 2
Also saw dust, a huge problem in saw mills and carpentry.
Edit, just saw you tested it already, the moisture content has a huge influence in the outcome.
The fresh sawdust had probably quite a bit more water, than the other tested powders.
And thermite!
@@kilianortmann9979 Saw dust mostly contains bigger particles, but these fall down fast. The really fine stuff which stays in the air much longer ist the big problem. In wood shops there´s also sanding dust, this mostly is the fine stuff.
@@Matt_The_Hugenot - I like the way you think!!! I'd also suggest Zn & S powder, as it makes a great rocket fuel
When I was a boy, I watched the wheat silo down the road take off like a Falcon 9 from a dust explosion. the shockwave knocked the wind out of me lol.. luckily, no one was hurt.
I was taught this at school in chemistry class, we used custard powder with great results!
Isn't custard powder made from corn starch and they tried that.
Corn starch and sugar mixed, fooof!
I went to an event once where a pyrotechnic team used a lifting charge under a volume of fuel to aerosolize and ignite it into a massive mushroom shaped fireball that made the whole crowd take a few steps back. Do something like that because you've got the people and location to do it safely.
Sawdust. That laugh after describing all the effort to make it was worth the whole video.
"Non-dairy creamer" is what you're looking for. Plenty of personal experience (also Mythbusters) has proven that it makes great fireballs.
This was the comment I was looking for
The tricky thing is that it’s very much a US thing. It’s not that it doesn’t exist outside the states, but it’s very, very hard to find. Most people wouldn’t know that it exists, unless they were to buy it from a specialist store that imports food and things from the USA.
There seems to be some relatively easily available in Finland. I searched for coffee creamer and found some vegetable based ones from websites of grocary stores.
Coffee creamer it is called here
Used to get kicked out of the McDonald's when I was in my freshman year in band!!!
There's something called "lycopodium powder" which is used in special effects because the dust burns extremely well. You could also try activated charcoal
I remember one of my elementary school teachers brought lycopodium (heksemel/witch flour) once. He thought us how to throw fireballs by putting a spoon of powder in the palm and make a motion to let the powder fly through the flame of a lit match stuck in between two fingers. Or the easier way of just packing it in a drinking straw and blow it out through a flame. Foooof.
It's a super fine pollen or spore I think used in elementary schools in surface tension experiments
I don’t know about activated charcoal... it’s reliably porous but I think it might sometimes have higher mineral content than regular charcoal and might not burn as well. I’m not sure, though.
Hard to get, when Rammstein buys nearly the whole yearly production for their concerts 😁
@@foxlima as long as it isn't being wasted then!!🤟🤟
My garage is a "workshop-grocerystore-mayhem-area".
Non dairy creamer. It makes excellent mushroom clouds when used in firework displays. We layer a metal 5 pound coffee can with alternating layers of 3f black powder and creamer separated by news paper.
Aluminum powder was used in Shuttle's solid rocket boosters.
^^ "scientific pepsi bottle" that totally got me... XD
Learning tip :
Flower = Parts of plants that look pretty, sometimes smell nice and that bee's and butterflies like.
Flour = Extremely fine grinded grains & seeds (aka wheat/corn/rice) that's used in baking.
It's always good to learn something new everyday. 😉
Lycopodium powder
is often used to demonstrate dust explosions and magnesium powder is very bright so those would be interesting to see.
I love it ‘This is stupid don’t try at home’.. love you guys..
The Mrs facial expressions during the intro was hilarious.
My dad accidently lit a box of magnesium dust/shavings it burned 6" concrete it made the paper where we lived at the time!
An old volkswagon engine or gearbox case on a big bonfire is pretty exciting!
Lol must be fun to watch also it can kill your eyes too and you can make flash grenade with this:)
Well this is great timing, I was just watching The Equalizer 2 when he was going throught the bakery, cutting open bags of flour, turning on fans - and then a big explosion. I was wondering how real that would be, outside of Hollywood making everything bigger and louder. Excellent video again - thank you!!
Lycopodium powder! Also known as Dragon Breath. It is very fine, dry moss spores. Used for fire breathing and fireworks. Enjoy - you're welcome.
How about some copper powder for part 2? It should burn green.
I haven't done a lot of research about that one yet but it might be too toxic.
Strontium and Uranium work well, too 🙊
Titanium and magnesium would also be fun
and add some zinc to spice it up a bit ;)
@@andrebartels1690 uranium? Really? Rather burn lead than that
"I made this in name of the science" XD love it!
If Finland has a tourism department they need to hire you guys ASAP. Honestly if I ever get a chance to go to Finland I’m taking it based solely on you guys.
I work with Grain, and there have been some horrific accidents with grain dust.
there are example on RUclips.
Usually its not the initial explosion that is the problem, it is the accumulation of dust which is blasted into the air leading to a secondary explosion this causes greater damage.
I wonder if this happened in 2020 Beirut explosion after the fertilizer blast affected z grain silo.
Hey guys, just wanted to say I'm a huge fan and idoliser of you two. Very good video, couldn't have done it better!
Some vocab that might help in discussing this topic:
Aerosol (Aerosolize): a mixture of a substance with air - which is the aim of this experiment to create
Density: how heavy a given volume of something is, e.g. the iron powder has a much higher density, so therefore the same volume contains more mass.
I'd love to see a dust fireball in a refrigerator, a portable toilet, or a car that doesn't run any more. Maybe add something like 250 grams of corn starch per cubic meter of air volume, and a powerful fan to keep it airborne. Hold the door shut with steel banding, and trigger it from a distance.

You are not ready yet!
Back in the 80's when I was a teen people were taking Nutrasweet(fake sugar)and a cigarette lighter,blowing it over the flame and torching people's hair that shit is flammable as hell
Need some titanium powder as well! Fun times!
I worked in Disneyland Paris in 1992 for 5 years. I made the flamethrower of the dragon parade float. The flamethrower worked the same, pushing a small amount of lycopode (it's a mushroom) powder through a gaz flame, using compressed air.
This video was LIT. :)
Be carful who you tell about this experiment. I once got fired from a job I worked 11 years at for doing experiments with burning sawdust at home on my own time.
You could mix some other materials to get a color change in your flame. Powdered copper sulfate will make it green. Borax will make it green also. Potassium Chloride will make it purple.
Edit: Coffee creamer powder is a good choice - try that.
When I tried Fire-Breathing, I used Cocoa / Drinking Chocolate powder and blew/spat it out on a lit torch. worked well, so maybe try some of that?
You need lycopodium. :) Its what we used for our flame thrower and also the powder of choice of Rammstein :)
Yes artifical creamer is very flammable. They did it on Mythbusters
Try magnesium powder next time !!!
Definitely.
Agreed! Nice white flame. Might want eye protection for that one...
@@disgruntledegghead6923 Mama always told me not to look into the eyes of the sun
...
@@OhioCruffler But Mama, that's where the fun is!
@@disgruntledegghead6923 Yep definitely not going to look at that. Even solid clump of the stuff burning is really bright so I think 10 meter tall fire ball is going to be pretty bad :D Also I want to pretty far away since radiant heat is going to be pretty good from that one.
I a different industrial situation I found out how flammable automotive wax and grease remover is. Very flammable!
I was welding a skin on a car, and as usual I keep a spray bottle of water handy to put any small flames out. A new guy put the wax and grease remover bottle with the water bottles. Funny part is I sprayed it twice before I figured it out. Pretty fire 😍
If you do this again, try it with cinnamon. I've seen a video of cinnamon catching fire while being dumped on a guy and I bet it would make a huge flame.
Great video! Also try dust in an enclosed container......like a five gallon bucket turned upside down on top. Will it launch the bucket?! Good stuff!
Looking forward to the magnesium and aluminum powders. You might want to wear welding goggles to protect from ultraviolet damage. The standard material for dust explosion demonstrations is "lycopodium powder", the spores of the club-moss plant. They are small and uniform in size, with high energy content and are very hydrophobic, so they stay dry and don't clump.
Nice tests, very interesting. Try it with rice flour, the one with the smallest particle size. Rice processing plants, where rice rice is packed, always have a thick atmosphere of dust, and it is extremely easy to ignite, as if there was fuel in the air.
Great video. Get titanium powder as well! And have a look at zinc/Sulphur. Dangerous, but cool
I literally laughed out the fizzled out end. Good job. Thumbs up.
It would be nice to see all the test composited into a single side-by-side playback to compare them.
I’ve seen aluminum dust go up first hand. I’ve also seen the aftermath of a few hundred pounds of aluminum chips from a mill going up in flames. The company that I worked for had a sodium light explode on the back dock which dropped super hot shards into the chip bin. Caught the whole back dock on fire and they had to call the fire department to foam it because the fire extinguishers weren’t rated for metal fires. Popped all the concrete and they had to replace the entire back dock. Metal fires are pretty interesting
This was cool! Please do this again sometime!
In most industrial accidents the powder falls down from the beams in the ceiling so it has time to get finely divided in the air before it hits the ignition point. That causes a bad deflagration. Since you are not afraid of such things could you set something up so the powder falls say 3 or 4 or more meters before hitting a small flame at the ground? I bet that would make a big whomp.
Best video on this topic ive seen so far! Maybe you could try some different mixtures of these powders? Would be interesting if this has any effect:)
Whenever you hear
"This is stupid"
You know it's going to be a great video
As others have suggested, the “powdered milk” you want is non-dairy creamer. Also try sanding dust instead of sawdust, it’s much finer. Another thing to try would be confectioner’s (“powdered”) sugar instead of granulated sugar.
He can be difficult to understand sometimes, but I'm pretty sure he said powdered sugar when he was behind the camera, even if he said just sugar first
Should've included cinnamon
Coffee creamer powder is the one you want to test next. That stuff is pretty flammable. I remember how they tested it on Mythbusters.
Here in the states we have exploding grain silos. The dry dust from the grain is extremely flammable.
Powered coffee creamer and cinnamon would be cool. Sparkling flames.
I work in a feed mill. (Chicken feed). And the amount of dust in there scares the shit out of me. We were told if we survive the first explosion to get out immediately because the secondary explosion is much worse.
Suggestion for this particular WMD: finely ground metal salts. Not sure of toxicities, or even if they will ignite, but if they do, you'll get some awesome flame colours.
Anni looks very worried
I was having fun watching her awkward/bored nodding for the intro.
And I bet she’s just chilly and anxious to see some explosions.
I think aluminium powder would have been a clear winner here. I used to work with military explosives, it's used to intensify the heat from a TNT blast. I also worked in an aluminium powder factory, they informed me during induction that it was the only one in the southern hemisphere that hadn't exploded yet ;)
Those slomos are trippy man.
Test idea: supercritically chilled soda vs. mentos.
A friend of mine worked in a plant that refined lacquer thinner from body shops where they clean their paint guns and such. The paint that was removed from the lacquer thinner was in a powder form after it dried and was in barrels and before they could put the lid on them they would all have to dry out.
They said if a fire broke out not to use a fire extinguisher on it. you had to smother the fire out because if you use a fire extinguisher it creates a cloud of the paint dust which will explode.
Well, Another guy that I know that works there noticed a barrel on fire and instead of laying a lid on it to smother it out he hit it with a fire extinguisher. the whole plant exploded! No one was hurt but the complete plant was gone. I live 5/6 miles away and heard the explosion.
Good stuff! cant wait to see part 2!!
I once tried powdered laundry detergent, squeezed from an empty 2 liter bottle. The flames were brief but impressive.
Very cool. If you are trying aluminum and magnesium try also titanium powder. Also - try pine charcoal powder and you will get a red fireball. But it has to be fine powder.
if you haven't already, try fine dry pine wood dust from sanding, (not chainsaw shavings) could make a good show of flame. only need to sprinkle a bit on a fire and it reacts well.
Awsome!
Don't let those guys who act genuinly disguting towards other persons in the comment line (i am not going to mention any names but one of them runs a pretty big electrinic related youtube channel) got the attention from all the fun and the genuine love and friendship here! Your work are awsome! I realy hope that there will be more collaboration with Sons of explosives in the future!
I used to drive combined load of pallets with wheat flour with pallet of plain butter on top.. 26 tonnes in semi trailer. Good combination to get some long lasting heat if it caught fire.
Not sure if the milk powder is the same as "Coffee Mate" but as a kid I would throw handfuls on a fire and get a good flare up. And squeezing and orange peal next to a flame is fun. Not that I was ever a pyro when I was a kid.
How many explosions have occurred at plants from food dust that has ignited? Even sugar ( Imperial Sugar Co. in Georgia 2008). Several.
Cinnamon, Lycopodium Powder and Non Dairy Creamer.
I actually worked at a sugar shipping plant and sometimes large pikes of sugar would self ignite if we left them in top large of piles for too long. I didn't believe it until I saw it for myself. I couldn't wrap my head around it but sure enough a large pile of sugar we couldn't get to during the week I came in Saturday to finish and it was smoking by itself
Easy way to make sawdust. Get some wood smoker pellets (or other processed extruded wood pellet) and slightly dampen in, then bake in a foil covered but vented large shallow pan at 200°f for 20 min.
One could use a 100 proof liqour and skip the oven, air dry for 2 hours in direct sunlight.
If it's extremely fine powder, it works even with granite rock. It goes so far that metals and rocks as extremely fine powder not only burn, but really explode.
👍🏼 Corn starch: ask any wok-master! 😋
öpölöök powder
Liked before watching because this is great idea ☺️
I think if you increase the pressure and try to get the dust out in one go, not so much like blowing continuously, that would help.
Mythbusters did this once, they tried milk powder and got a huge fireball out of it.
Saw dust in various sizes ranging from dust size to grain size would also be good.
Good video idea. It'd be cool if you could edit the shots of the flames side by side for comparison.
Sawdust is EXCEPTIONALLY explosive but you need a realistic particle size to replicate the explosions that happen in wood industrial fires. Those are almost always caused by very fine particles referred to as "wood flour". Frequently industrial cutters spin MUCH MUCH faster than circular saw blades and produce much smaller dust particles, which ignite explosively in the presence of spark.
“Don’t try this at home”... Ok, I’ll try it someplace else! 🤪
According to Macgyver, copper and zinc powder mixed together should make nice sparks ;)
i love how they say . dont try this at home its really stupid
and it is always an epic video
The problem with this setup is you're burning the stream of dust continuously rather than letting it aerate first, then ignite (which is what creates a proper dust explosion). I don't know how fast your propane torch ignites but I'd try another test where you loft the dust first, and then try to ignite it. Obviously, take appropriate precautions.
You need to use the air cannon, the bottle's neck is too small for the volume of powder. Air speed needs to be fast and sudden.
For wood dust, the best (smallest) comes from a sander. Saws give you chips, not dust.
Make sure you are up-wind, even the non-toxic stuff isn't good to breathe.
Also, you missed two powders, gun powder and thermite powder.
I’ve done something similar with powdered coffee creamer and had great results.
Grain dust is far more flammable than flour is! You can find it anywhere with large grain bins; it's generated by all of the grain rubbing against itself when it's moved. Usually a grain elevator will have a dust extraction system that has piles of the stuff at the exhaust port. My two favorites are wheat and barley dust. If you can't find any, let me know and I'll send some!
Need some sort of graph on the wall behind the flame so we can compare the fireball size of each product.
Maybe you need to mix in some potassium nitrate in the powder? Titanium powder also burs good, but I guess it is to expensive to just burn it off. But if you have some, try it!
Wood dust would make a good show, the really fine dust from sanding. 120 and 180 grit with a DA sander makes really fine dust.
Do a comparison with lycopodium. Others have said Mg, Ti and charcoal, which I second. You can also do liquids: do colored fireballs with methanol and either LiCl, SrCl2, CaCl2, NaHCO3, H3BO3, or CuCl2+HCl.
I've tested all of these.
LiCl: the salt is very hygroscopic. It's easier to make a saturates solution in methanol, and dilute it 1:10 for use
SrCl: probably same. I haven't used it much, because it only works in fireballs, juggling or other situations where there is movement. Same with CaCl.
NaCl works, but NaHCO3 gives more even color.
H3BO3: you want a saturated solution for the best color. For all others, 10g/l suffices if you use the dry chemical, or 1:10 of a saturated methanol solution shoud suffice.
CuCl2 needs free chlorine or HCl in the flame. Add 1 part HCl solution to 3 parts methanol. The mixture will get warm but not hot. You can use a chlorinated solvent instead, if you have access to it and don't want to deal with the acid.
I would suggest trying cinamon! It makes really nice sparkles! :D
Cinnamon might yield a nice visual.
For more interesting result - add table salt into the mix. It contains sodium so it will give a very bright yellow color. Also try some other salt like potassium salt that should give a purple flame. Stick to stuff that's not going to be unhealthy so no mercury or beryllium.
This used to be part of my job but, with coal dust. There is huge variability in the type of coal, size of particle and availability of oxygen but, once combustion had started then there was little to be done to stop it. Even if you could do something, you would have very little time to act.
I've heard stories of brewers milling barley grains and getting burnt by the powder igniting. Finely crushed barley may be a good test if you ever do this again.
Try and get your hands on corn dust. Here in the U.S. grain bin sights get destroyed because of corn dust fires/explosions
