- In this video we are going to make some super simple and cheap rocket motors using 1/2 PVC pipe, Stump Remover (Potassium Nitrate), Powdered Sugar, Sulfur, and Bentonite Clay (Kitty Litter).
Parts List:
1/2" PVC pipe (clear PVC here: goo.gl/5sgfD4)
5/8" Wooden Dowel (sandpaper to adjust to size)
Stump Remover (Potassium Nitrate) goo.gl/9dL5vs
10X Powdered Sugar
Sulfur Powder amzn.to/2LxWlFB
Bentonite Clay (finely ground kitty litter) - Věda a technologie
For people new to rocketry, have fun with these but do not overdo it. If it blows up, plastic shrapnel is incredibly hard to detect on x-ray. It's better to have a larger nozzle diameter which may not create a lot of thrust over a too small nozzle diameter and a massive CATO. If you want a lot of smoke also put just a pinch of baking soda in
Thanks for a very informative explanation and demonstration. My son and I are brand-new to rockets and all that go with them. Your knowledge and inight are fantastic. Thank you very much.
@@frankwestphal8532
Thanks very much. 👍🏼
This was a damn good video. It caught me by surprise, too. I've been screwing around with a dry packed powder mix for my rockets, and a couple days back I had the idea of milling some crayon shavings into my powder, thinking the wax would act partially as a binder and also to surround the oxidizer particles when the flame front hits and melts it. And now here it is in living color, way before I ever thought of it. Damn. This channel is AMAZINGLY good, so this lets me know I'm on the right track. Cheers for the reply on the aluminum video. I'm ditching oxide catalysts and going sulfur after seeing this.
Glad your enjoying the videos Rex! While iron oxide is a great catalyst, I found sulfur to be a bit easier to work with for a compressed sugar rocket. I'm sure a couple percent iron oxide would bump up the specific impulse a bit more though, so it's probably worth a shot.
All my rockets with 2 % red iron oxide blow up...

Have you noticed that when American's need accuracy - they switch to METRIC!
Any unit can be accurate
@@michaelschuler7397 You may use metric to be accurate, but you use Imperial to go to the moon.
@@frankduncan5685 but they will be using metric to go to Mars. 😁
How many metric flags on the moon?
@@Ninja1000sx. remember when NASA used imperial instead of metric by mistake and one of their mars landers crashed...
Very nice. Saw your caption and had a wash of childhood memories return. Back then I got my potassium from the hobby store that sold supplies for Gilbert Chemistry sets, made my own carbon by charring wood. Had lots of success, but turned out Cub Scouts didn't offer merit badge credit for such adventures. Thanks for sharing.
Jay Littleton I wish I lived in the days when you could get potassium nitrate from the drug store! How awesome that had to be! Thanks for sharing your story and checking out my channel!
I imagine there are ready sources in small quantities other than the stump remover. I was all set after my post to see what I can get to make up a batch of "Christmas Lighting Effects" but my wife put the Cancelled stamp on that REAL fast. sigh.
Superbly produced!
What class would a homemade motor this size be? Looks to be a C or D size, but what about the actual power?
ive made engines this size and they were approximately between a c and a d for power.
You will probably get a much better reaction by taking the Potassium Nitrate and sugar in a pan and caramelizing it, then adding aluminum powder. But first place the potassium nitrate in the oven on low heat for 30 mins to draw out any moisture in it.
Great video greatly appreciate you making it
Excellent video. All the details I needed!
Good job visual and verbal instructions clear to understand and No background music
And he gets straight to the point
Nice but I like making rocket candy and using some rust or aluminum powder that has been oxidized as a catalyst..
What I like is you can form them while in a hot past like form into paper molds and when they burn off they leave amazing white plume trails to track your rockets.
Cool video, those motors are costly , if you want to fly a lot, nice to know how to make them, nice video!
Thanks for the cool video!
Great video!
Use an acid brush to clean your moving bit.👍
wow. i actually guessed your first quantity (67 g) was a percentage of 100 g, and after you said the second measurement (27 g), i predicted you would say 6 g of sulfur. thanks for keeping it simple for scaling!
I always try to keep it simple!
Definitely taking notes on this video. 👍
Don’t know much about chemistry so this might be a dumb question...but anyway, how do you know what proportions to use in making the propellant?
From narration
67g KNO3
27g Sugar
6g S
Originally, trial and error.
I had been wondering if sulfur would be a good burn rate catalyst for KNSU motors, considering that it serves that purpose in black powder. Though granted, I was considering a melt/cast or recrystallized propellant (ala James Yawn). I might have to experiment.
Thumbs up from Norway 😀
Thank you Terje!
This is awesome. Exacty what I was looking for with my class.
Now all that we need is the smiling group of locals I saw on my trip last year to mexico to visit ElementalMaker so they can launch these rockets from his great tutorial from their fingertips while he records as they share a funny smelling huge cigar between each other to set off the rockets fuses. Cheers to Tultepecs great fireworks!
That was simply awesome.👍
maritimer Man glad you enjoyed! Thanks for checking out my channel!
Hi there, really good video and greatly informative. How do I dry out potassium nitrate that wasn't stored in an air tight container please? Keep up the great work.
you can dry it in an oven at 150°C for 2-4 hours safely
Spread KNO3 out on cardboard or cookie sheet. Turn oven ON lowest setting, when hot, turn it OFF and put KNO3 in 'til oven cools.
I've been subscribed to your channel for over a month, maybe two. I just hit the 'thumbs up' button. I'm also a basement chemist, and have made rocket motors before as well as flash powder. I've also mixed a 50-50 of Muriatic Acid (30% acid) and water to remove rust from metal parts. Once the rust is removed, I wash the parts with water and baking soda.
Thanks for your sub and thumbs up!
awesome rocket engines thank you.
This is kind of exciting. Watching a guy put homemade rocket fuel in a tube and then beat on it.
The pounding isn't so worrisome, but I figure that someday the friction of drilling out the core is going to set one of these things off in my hands!
either don't make rockets or DRILL SLOWLY by hand
@Charlie Montana Actually in powder form and mixed with an oxidizer, it's pretty common to get self ignition. Adding sulfur just makes it more likely because it has a low ignition temperature... Just static electricity could light a cloud of it off.
When making sugar rockets I usually mix the sugar and KNO3 together with just enough water to dissolve them, put it on the stove and boil the water away. Take it off heat and let it cool a bit when it gets creamy white in color after it boils for a while, that means all the water is gone. After it cooled a bit but is still liquid, pour into your rocket, and insert a piece of magnesium sparkler in the center of the core as a fuse. It will set into a perfectly mixed anhydrous sugar and oxidizer solid fuel, and the magnesium sparkler will easily ignite it even without sulfur. Because the sugar is mixed better with the KNO3 by dissolving with it, you don't need the sulfur in there. It's also much safer to handle than in powder form.
Great vid!
But which one to you consider safer to make, this one or the KNSB?
Both are very safe propellants when done correctly.
ElementalMaker thanks a lot!
Great video! I guess because you used powdered dry clay, I assume as the engine burns, the nozzle clay inside ablates to form a convergence cone, and the exhaust hole ablates to form a divergence nozzle. I use use hydraulic cement and wooden forms to shape the convergence cone and divergence nozzle, by having these geometries at launch, the rocket efficiency remains relatively constant throughout the burn.
Great video
I read a few of the comments and they don't seem to understand. This exercise is fun and safe to be shared with kids. I understand very well some of their comments but they're also talking chemical reactions that would be more than a third degree burn maybe more than that to your neighbor the quarter mile away. Great video as usual and with respect to making chemistry and physics fun to learn and life fun! Light up people it's not a video on shaped charges of thermite! Let's play nice and I wouldn't advise making three and a half pounds of rocket fuel unless you are going to get your unfavorite brother-in-law to do it haha!
Any idea what kind of fuel they use in those “Whistling Moon Travelers?”
They scream when they go off and imagine the sound of one ten times the size!
Those are made with a composition called whistle mix. IT'S usually K C L O 4 and potassium benzoate if I'm remembering correctly
I'm a lot more used to watching you review chainsaws! 😄, good tutorial though 👍👍
Chainsaws? Huh?
@@ElementalMaker i think he means you sound like AvE
Nice work.
1:06 can you please explain how you did it? Would the molten wax just clump up and make a mess?
You have to heat the clay powder up just past the melting point of the wax, and then thoroughly mix a very small amount of wax in while it's hot.
How did you melt the parafin into the bentonite clay and still end up with a fine ground product?
Just put a bunch of clay in a loaf pan with a half a block of paraffin then threw it into the toaster oven for about an hour at a low temp. The bentonite seems to absorb the paraffin very nicely. It clumped a little bit, but once cooled easily powdered again just by mixing with a spoon.
Can you use Sweet and Low instead of the sugar? I'm on a diet.
jet li yes you can
@Goolius Boozler only in the state of California. 🤣
@@kreynolds1123 Well then you’ll just get cancer
jet li - Actually, it something like artificial sweetener Sorbitol works better. See others on CZcams that use it. However don't use it yourself for sweetener. Stick to real Stevia.
What if you used a cone shaped bit to drill your exhaust hole? Would it increase your thrust?
With this size of motor, any increase in efficiency would be too small to actually measure except on the most sensitive of test stands.
Thanks for the video.
No stump remover to be found on Long Island NY....what else can be used...??
Kennynva T. You can directly order potassium nitrate from many sources online. You could also ask a local hardware store to special order that specific stump remover for you.
You can order Spectracide Stump Remover from Amazon. Not all stump remover is made from the same chemical. You want Potassium Nitrate. Also known as saltpeter (saltpetre). It's also used for pickling and as a fertilizer.
where did you buy your black box ?
You also can ( do it outside since it may burn) melt the sugar goo and cast it to cylinders.
i got a real large tonka dump truck... can i move this up 20 times for say 40 mph?
You might consider ball milling it in a rock tumbler too.
If you use a ball mill, divide the mix into two batches that are in the wrong proportions, like half of the K-nite and all of the sugar, then the other half with all the sulfur. Carefully mix the two batches thoroughly in a pair of paper cups taped together to form something like a cone powder blender to get the final mix. A vibratory polisher with plastic media might also work. The two half batches won't burn properly, so they are relatively safe to mill to a fine powder.
I just love this!
Love the video.......crazy chemist ......note wash the stump remover and get 100 % .get the inerit. Out .........boil in hotwater.......evaporate
To all cheers....
M
Why thank you! And per the stump remover, Its already 99.9% pure kno3, no need to recrystallize. Per the msds its 100% pure actually, but that would be better than reagent grade.
you might find it easier to load granulated mix made by wetting your fuel mix with a small amount of nitrocellulose dissolved in acetone and pushing through a screen. Granulated loading stock always makes for more consistent results compared to powder. We make huge colored smoke cartridges professionally and loading powder/dust is out of the question. You can find ping pong balls made of NC and use them.
Add some flash powder, or finely ground aluminum to improve combustion rate........
Most people making small rocket motors probably know this, but I want to mention that PVC and some other plastics can create rather nasty shrapnel if the motor goes boom. Which is unfortunately not to unusal when trying to optimize them... I had to research this at work and the worst materials were PVC, PEEK and surprisingly nylon.
Polyethylene is safe and therefore often used in firework mortars. Not a good casing material thou since it creeps under load. Fiberglas behaves fairly safe as it delaminates/splits in flakes more than creating shrapnel.
I would suggest using paper tubes for small rammed motors like this. You can roll them in any dia and wall thickness from virgin craft using wheat paste or white glue. When ramming the composition bites into the walls better than in plastics, so fewer booms and safer. Note that the paper tubes need to be parallell wound, not the cheap spiral wound leftovers from household items. It is a traditional method well worth learning.
They make them that way in Mexico, and they are very reliable. People launch them from their hands.
The cheap cat litter I found had some crystalline silica in it. Is that okay?
When I was in the 6th grade a friend of mine brought a bag of batteries, pens, and just random parts. One of those parts just so happened to be a rocket engine. At some point someone thought it would be smart to connect the engine to a 9v battery while in the bag. I still remember my science teachers face when the smoke cleared after zipping around the room. Oh and our teacher had a farthing problem, he told us a story about him having to have part of his colon removed making him unable to hold his facts and he would rip 5 or so per class. I mean they would rip and you know how hard it is to not laugh when you're taking notes and all the sudden the silence is interrupted by a feat? Yeah we all got written up time or two.
You're like to see you actually launch rockets. Build some with shoots and launch them. Will be cool. Love your videos and got seen in awhile
Wouldnt narrowing the outlet provide more thrust as the gasses will propel at a faster speed?
Yes.
Cool thing he uses to move the powders. What is it called?
A thing here, dont use a metal whatever to stir, unless you got a paper cup as he has. Use soft things, even wood. As lomg as it cannot spark or cause friction, and metal together with porceline is a very bad for self ignition ( has happened me once)
Good Job.
Where do you get the sulfur?
So, in theory this can be as wide and as long as we want? And will it be better if we make it longer ( stays in the air longer or launches faster )?
It's a different set of calculations. On a ported rocket, lengthening the port causes more volume to be burning at any one time and increases pressures, which could be good or bad, depending on where things are at. Changing the diameter can have an even more profound effect but then you pick up the issue of maintaining the clay plugs because the area on the plug increases much faster than the diameter or circumference and the amount of fuel burning at any point in time varies more as it burns from the port toward the outside of the engine and the area increases. If you switch materials for the plugs, you need to not exceed the pressures of Schedule 40 PVC by too much. It will take quite a bit of trial and error and you will want something that measures and records peak thrust and knowing the diameter of the nozzle to know where you are on pressures. They make some pretty big sugar rockets here on CZcams. Learning from those guys can get you into the zone you want to be in more quickly and you can take it from there.
Spacex move over. These are like the ones I made in high school 60 years ago, but I used plaster of paris for nozzles and plugs. Was no pvc then (that I knew of) so rolled up paper tape. Half would explode. I used a black powder fuel wetted and slowly dried. Dextrin added to the fuel for binder.
Do you know like a recipe for powerful rocket fuel a thrust of 3 lbs or up
What is that an equivalent to, an E motor?
This is good info. However, you just showed us a small motor. If we used the same ratios, but a longer tube, would it function to push a rocket to higher altitudes, or would it not work at all?
It can certainly be scaled up. Check out my newer rocket motor videos. I also built an arduino based test stand to quantify thrust data.
Simply amazing and great to know. Thank you.
What class rocket motor is this , B4 or A
I don't thing you can buy stump remover here in Quebec Canada anymore. If any knows where please share where.
Nope, not since 2013, it's on a list of "restricted components" which means to sell it you need to have a license. And it's not just Quebec, it's a federal law. You don't need a license to own it, but you must comply with some regulations for storage, transport, usage, etc... www.nrcan.gc.ca/explosives/restricted-components/9981
In short, you just can't buy it in hardware stores anymore, but anyone can own it as long as you don't intend to sell anything that contains it without a license. They just made oxidizing agents and reducing agents harder to buy for someone who shouldn't be handling it in the first place. Here is the whole list of restricted components:
456 (1) The following components are prescribed for the purpose of the definition restricted component in section 2 of the Explosives Act:
(a) ammonium nitrate in solid form at a concentration of at least 28% nitrogen;
(b) hydrogen peroxide at a concentration of at least 30%;
(c) nitromethane, UN number 1261;
(d) potassium chlorate, UN number 1485;
(e) potassium perchlorate, UN number 1489;
(f) sodium chlorate in solid form, UN number 1495;
(g) nitric acid at a concentration of at least 75%;
(h) potassium nitrate, UN number 1486;
(i) potassium nitrate and sodium nitrate mixture, UN number 1499; and
(j) sodium nitrate in solid form, UN number 1498.
Acquisition - others
459 Any person may acquire a restricted component for a purpose other than manufacturing restricted component products for sale.
You should be able to boost the performance of this fuel by adding between 0.5 and 1% charcoal. This is not for the chemical reaction, but for the opacifying effect it has.
Great suggestion, I will have to give that a try!
@@ElementalMaker Let us know how it goes :)
Well??? How does it work?
@@andrewostrelczuk406 - A lot of the energy in the combustion is in the form of light. If the fuel is transparent to these light frequencies, then the energy is transmitted straight to the casing. But if you have charcoal in the mix, this absorbs the light energy at the surface and helps heat the fuel at that point, which means that less energy is used to turn the fuel into a plasma and more can be used to get the gases going out the nozzle faster. It is a small but significant amount.
I was thinking about the result of the mixture. Better results or same, or even diminished returns on the labor and experiment process. I hope that you don’t take this as dismissive to your explanation, that is fascinating. A bit of a wow effect!!! Back in my Middle school days We had a wonderful gifted science teacher, who got me started with Rockets, I was classified as a “Basement Bomber” for building my own design rockets... Got teased a lot about it till the day(s) for Launching. Then my Redemption was clearly much sweeter than the some of the other Popular kids designs. Most of which failed in some way... two of them were perfect in flight and recovery. I was amazed that my rockets had constantly developed broken pieces even before launch day and had to repair both on the launch day, balsa wood fins were broken most often. Thanks to my Mom giving me a tube of new Supper Glue, I was a successful Rocketeer.
So, this is essentially black powder, with sugar used as a higher power alternative to charcoal for the carbon source.
Three things: Do not mix this stuff in a blender or spice grinder. This is an explosive and too much friction can set it off. Grinding the individual constituents is fine, but together, just don't even think about it. Secondly, be very wary tamping this stuff down. Too much friction or force can set this stuff off easily. And sugar is sticky if it's humid out. (Let me say one name, Phineas Gage.) Thirdly, yeah, absolutely, a very low speed drill, use a hand bit and brace if you have one.
Red iron oxide is a good catalyst too if you have no sulfur. 1% by weight of the combined fuel and oxidizer. Rockite anchoring cement is also better to use as a nozzle.
Are your proportions of KNO3 , sugar and sulfur just basically gunpowder?
Your videos are much better quality than Jimmy Yawn's I watched years ago when I first made candy rockets! Well done!
How much wax was mixed into the clay ?
0:48 Potassium nitrate, sulfur and a source of carbon. That sounds strangely familiar!!!
Lovely blackpowder :)
you can smell it from here! =P
So are all explosions the result of reacting a fuel and an oxidizer really quickly? Are there explosions that happen completely without some form of oxygen?
Michael Knight most often they use oxidiser but some chemicals explode by reacting with themselves
@@michaelknight2342 Any strong oxidiser will work, obviously, oxygen from the air is easy to obtain. That's why the operators of sugar factories and flour mills are VERY careful, a factory full of flammable dust with every tiny fragment surrounded by oxygen can be fatally explosive.
Chlorine works nicely as an oxidiser, the reaction of hydrogen and chlorine, for example, is spontaneous except in darkness. The activation energy can be supplied by light. There's probably a CZcams video of it.
Some rockets use hydrogen peroxide as oxidizer and hydrazine as fuel. The WW2 V2 rockets used alcohol and liquid oxygen (I think). You could look up "hypergolic fuels" for more information and/or the launch escape rockets being (and that have been) used by NASA and SpaceX.
Any rapid chemical reaction that produces a lot of gases very quickly is an explosion, but if it's confined for the first fraction of a second, the gas volume builds up and it's more of a bang than a whoosh. If you look at a "banging" firework, it's small and solidly built to allow this.
Some explosives have their own oxygen, which is released when they get hot, or when they are pressurised. TNT and dynamite are examples of these. Again, it's about evolving large amounts of gas very rapidly.
How do you get the paraffin (wax) to blend with the litter? Do you buy paraffin already pulverized?
Buy it at hobby store like that or use a coffee grinder.
this is how NASA build its rocked engines :-D
What do you use as an igniter?
I have a video showing how I make igniters
Does it scale well? Could I do a 4 inch diameter version?
Has anyone tried this but used 2" or 3" pvc or a cardboard tube? I've been experimenting using cardboard tubes as pvc tends to break down with the heat. My problem is that I need more thrust.
Hello! How much paraffin must be added to bentonite clay to make a free-flowing mixture? How is mixing done? Thanks for the answer. I wish you success!
I just eyeball it. I heat the bentonite/grog mix in the toaster oven. Probably 1.5cups worth, and add maybe a tablespoon worth of paraffin wax
How stable is the fuel? Any chance of explosion when using the hammer on the fuel?
For what reason you put the delay on top?
Parachute ejection charge. You want a delay before the parachute pops
For the sulfur. Can we crush matches head in powder
and get same result as yellowed one?
No match heads are a very different chemical composition. Very dangerous actually. You need pure sulfur.
Lmao phosphorus != sulfur
If you have or can get a metal lathe, you could build a rig, that would allow you to make a spike over which you place the rocket motor body. You then pour and tamp all of your rocket motor ingredients (the clay, fuel, etc.) into the motor body, and the spike automatically has a space already made so you never have to drill the motors again! :-) A mandrel if you will. The spike mandrel would allow for the hole you have to drill instead of having to drill it, and you would also have a tamper, that is designed with a hole in the middle that the spike mandrel fits snuggly into, so you can tamp the ingredients around the spike mandrel! :-)
Check out my newer rocket videos. I did just that. I made this video for people who don't have access to a lathe. I can make five massive motors on my 3/4 spindle setup in about ten minutes.
Potassium perchlorate and sodium benzoate 70/30 would make a good end burning composition just like estes motors.
What about an electric motor, can that be used without chemical?
Any way to add your aluminum powder to this (possibly without the sugar fuel) to make a higher grade rocket fuel?
MotherEric aluminum usually isn't used with nitrate based propellants. The nitrate and aluminum can slowly react to form unstable side products (forget exactly what they are right now) that can case spontaneous ignition. Although certain compounds can be added to prevent this. I have experimented with ammonium nitrate based propellants using resin binder and aluminum powder
ElementalMaker,
Ah Okay. Sounds cool, and thanks for the clarification.
Not sure about you, but my potassium nitrate is always sucking more water out of the air than I'd like. Even if I baked the KNO3 nice and dry before mixing it I'd be hard pressed to make any claims about the stuff staying dry for any length of time. My attempts to protect these powders from environmental humidity always seem to be only partially effective.
If you want your powder to stay dry vacuume seal it with a silica packet works great I have these that are 2 years old and function like I just built them I put like 8 in a vacuum bag at one (food grade vacuum bags)
I have some stored in screw top plastic bowls for over 4 years and it still works,, R Candy with Kayro Syrup (spelling ?),,, and I can remelt it and mold to fit my shells,,,
do you need to put a delay mix in
If you want to retrieve your rocket via parachute, yes. If you just want to fire and forget, no. The delay is so your parachute doesn't pop right after or during your main propulsion as this can cause your parachute to get ripped off due to wind resistance.
I just blew up my moms brand new blender :-) Man she is going to be pissed LOL ..........Just kidding Hehehehe
I used to make sugar/potassium nitrate homemade rocket fuel years ago as a teenage kid and had pretty good success with some flying rockets....You took me back to my later teenage years watching this process and much more refined and accurate than when I used to make it :-) I had to stop buying the brown jars every week of potassium nitrate from my local pharmacy and when the pharmacist began giving me funny looks back then LOL I later learned that it was given in a dosage to military personnel to reduce their sexual urges when sent out on missions..... :-) Then for weeks I was too embarrassed to set foot back in the pharmacy :-)
Yes I remember when I sent my dad in the get some, and he came back and said "you know what this stuff is called? Saltpeter."
I’ve seen recipes where the sugar mixture is melted on a hot plate (no open flames..duh) then poured into the tube. This seems a much safer approach.
Any difference in performance?
I have done that many times. The only way i will do it. Burns better and evenly
Almost every other video I have see on rocket candy shows them heating the mixture till carmel colored. Does this make a difference in your opinion?
Yeah watch my latest video on making propellant
Super cool
Way cool 😄
So... In another video, you were combining KNO3 and C12H22O11 on a hot plate to make rocket candy. Here, the dangerous step of heating and mixing the fuel and oxidizer is omitted. So what would be the advantage of rocket candy over this mix, if any?
The heated mix is actually more energetic because it is a fully integrated mixture. The powdered fuel can't compare, although it is easier to pump out a bunch quickly.
Why have people overcomplicated this simple hobby? This, as seen in the video, was the way it was meant to be.
didn't know you could do this without making a supersaturated fluid mix under heat and slowly boiling it down until it co-crystallized.
@@arkhamkillzone eh, wut?
@@arkhamkillzone - ah, ok. I know a few things about a few things. and am old. and have a beard. so, um... yes? yes. yes, I am :D
Drilling!? Agh no way dude! Innovative way to get around needing a spindle/tooling I guess, but damn dude that's too scary for me.
Yeah, that seems a bit iffy to me, but it seems to work.
Greeting! Good video! When is a clay nozzle not needed? With smaller pipe diameters?
Just need to find that household sulfur of mine. I can't figure out where I placed it. 2:17 Hydroscopic, "did you mean hygroscopic"? Being that guy. Cool video.
Same here. 1kg of sulfur must be somewhere around me, but I couldn't find it anymore, so I just bought a new kilo.
I subscribed!
Thanks Joe!
why u dont use stump remover?
Hygroscopic* 😁 Great video! I work in plastics so I use the term often. Can't help but correct people lol.
Came here to say this. Great video though!
Remember to grind your own sugar if your powdered sugar from the store has corn starch, it significantly slows burn rate
so could that be a main reason my fuel is slow?
@@NOVASOULJAH it would definitely be a factor, but things like moisture content and particle size/ distribution also play huge roles. Also the fuel has to be under pressure to burn quickly, if your only testing in open air then it will look pretty slow
@@aidanflanigan9532 thank you for helping me :)
