Well done! I'm really honored you took my suggestion seriously! 😃 On a more technical note, I think the nozzles were falling apart during the burn, and that caused most of the inaccuracy. The ignition leads might have interfered a bit as well. However, I came to the conclusion that differently from bullets, spin alone is not sufficient to stabilize a rocket. Complex rotational instabilities appear as the motor burns that cause the rocket to wobble wildly. After publishing my original videos I found out that even some space missions were lost due to a spin stabilized upper stage wobbling out of control. I think that fast rotation, that was supposed to be the Gyrojet's greatest asset, ended up being its biggest curse.
I agree that spin stabilization with a rocket is a hard ask, but also, I don't think you'll ever achieve spin stabilization with the setup shown here. Because the shell isn't a tight fit in the tube, it's easier for the shell to slide forward than it is for it to rotate--just consider the surface area of a line down the tube compared to the surface area of a single revolution around the rocket's axis, much less the many, many revolutions you are looking for for spin stabilization. And as long as the rocket isn't spin stabilized in the tube, if there is any room for it to bump around inside the tube and end up with weird momentum coming out the end of it, it will. Frankly, what this rocket bullet wants... is to actually be inside a close fit, closed, rifled gun barrel, with the the barrel providing part of the spin, and the closed nature of the tube containing the rocket thrust to help overcome the friction and impart spin. Only once the bullet leaves, going in a straight line and spin stabilized, would the rocket motor even potentially help KEEP the spin stabilization, and even then as you say if the rocket motor burns unevenly or the nozzle gives way, the physics of the motor will suddenly change mid-flight, and that will probably overcome any benefit of the stabilization.
@@Anthromod probably not exactly that, since the axis of rotation is the one with the lowest moment of inertia (and not the intermediate one), which is stable for rigid bodies. However, non rigid bodies with ways of dissipating energy (like a rocket ejecting gas and burning propellant) tend to transition towards rotating in the direction of highest moment of inertia, which is "head to tail" for a rocket. The behaviour is further complicated by the fact that the center of mass is moving and moments of inertia are changing as the burn proceeds. Even nutation instability has been observed in space.

The fact that the grain isn't uniform is going to create a lot of instability as well. It _really_ needs to be packed tightly without air inside in order to ensure maximum stability. Also, these tests really shouldn't be done in the city. Imagine if it actually worked rather well, but went over the wall and hit someone... "Safety third" is only okay if *you* are the only ones in danger.
Because of the relatively low burn rate of the grain, making the nozzle a higher degree angle and also capping the back of the tube to allow pressure to build up will help significantly.

2:40 This stuff is known as rocket candy (since it's basically a sugar and an oxidizer), you can use it for low powered model rocketry. The reason why it's not generally usable for higher power rocketry is that it's generally very slow burning (compared to real rocket motors), and so a larger mass of it won't burn very fast. I have some friends who made some in their kitchen oven lol (this is pretty dangerous as too much heat can cause the propellant to spontaneously ignite!) Before you start making anything, you should check your local regulation on what amount of energy you can use in a model rocket without a license (where I am it's 80Ns). Do your math and chemistry, calculate out your yields before hand, and don't go overboard! If you do want to make some yourself, I'd recommend a temperature controlled hotplate or gridle, and definitely don't do this indoors! You can find KNO3/Potassium Nitrate online as tree stump killer, and most sugars will work fine (altho some may work better than others). Iron oxide is easy enough to find and technically not needed, tho it helps. Prepare your molds before hand! As stated before, overheating this stuff can cause it to ignite! The shape used in the video with the hole through the middle is the most common design in general for rocket motors, if you use a cardboard/reinforced paper tube you generally will not need to demold it, that can be lit with the rest of the propellant. This should go without saying but make sure you have proper safety equipment, safety goggles, fire extinguisher, clothes that won't catch on fire, etc.
funnily enough, conventional bullets would be way more effective in space. The jet in jet bullets tries to counteract the slowing factor of air drag. Unless you put enough propellant there to achieve a higher max speed than conventional bullet's muzzle speed, but that's basically an RPG, a small caliber won't cut it.
I missed this when it first came out. It has been a while, but here are a couple ideas to help the rocket bullets fly straight. 1. You cannot rifle the barrel to get a stabilizing spin, but what about the rocket exhaust? A rifled pinhole, leading to angled exhaust bells for the nozzles? 2. Fins and spin are not he only ways to stabilize a rockets flight path. What do a kite and a bottle rocket have in common? Drag. Some model rockets use a similar method for recovery with a ribbon streamer slowing it on decent. A tiny carbon-fiber ribbon attached to the center of the back of the bullet. Roll it up and place in into one of the nozzle bells to maintain the shape of the bullet when loaded. One fired, the exhaust should unfurl the ribbon, causing drag at the back of the rocket and forcing it to fly strait. Using drag alone, you could have 3 streamers placed equidistant around the back of the bullet rolled and placed into a central nozzle. I think they should be 2/3 times the length of the bullet. Should stabilize nicely.
That straw hat in the beginning made me cry. Rest in peace Danny from Taofledermaus. You were a hell of a shot and im glad you got to shoot the gyrojet. You were a uncle to many. Thank you integza for your video
That looks a lot like a center of gravity issue as well. Adding some weight to the front of the rocket may help immensely. If you look at the original Gyrojet, while it is hollow - the front 1/3 of the round was solid brass.
Yes. The CG (center of gravity) must be ahead of the CP (center of pressure) by typically 1 caliber (1 diameter in length). i.e. Add more mass to the nose tip.
@@garyjimmerson3393 And then you get spin stabilised projectiles - where the deliberately make them rear heavy so they turn over on impact… (both the British .303 and all the Japanese WW2 ammunition had this feature).
The gyrojet is one of my favorite forgotten weapons ever produced! Especially the long barrel version. Thanks for making this! Also, a steeper angle on your nozzles (about 45*) or thrust deflecting vanes on the backend may help solve your stability issues while maintaining the same bore size.
@@commandingsteel well, integza isn't in the US as far as i know, so that's all pretty irrelevant? youtube just is quick to hand out penalties for instructions on anything dangerous i think.
Video idea: Use the extra gunpowder to explode a tomato form the inside edit: I did not explain a lot yesterday, i mean for you to somehow put gunpowder inside the tomato and detonate it (don't know if it needs a container for the gunpowder to work since the inside of the tomato is very wet) Tomatoes are disgusting! And since I'm also allergic to Tomatoes you can explode them all!!!
He's making rocket candy, a propellant. It doesn't detonate, it burns. Explosives don't work as gunpowder or rocket fuel. Edit: Unless you meant the black powder, which is fair.
Put a sharp crease in a piece of paper put the gun powder on the folded piece of paper hold the edge of the crease over the straw and tip up until the required amount has been deposited. Great channel by the way !
Great video, as always! Maybe you could try adding nozzles on the side specifically to cause the high-speed gyroscopic rotation (kinda like those Speed Ball fireworks NightHawkInLight did a video on). If you can get those bullets spinning faster, they might travel straighter!
Honestly, at this point I'd love to just see you form nozzles out of clay on a wheel (oldstyle) and glaze them. I think you might get better results with way less complication. No porosity, far easier to prototype and I think you'd be surprised by the repeatability. Also, I think traditional glazes would hold up under the temperatures you are looking for.
You can put 3 holes in your nozzle in a triangle configuration rather than 2 holes. That would fix the stability issues and make the rocket bullet shoot closer to its target.
Try 1.) closing the back of the gun, that’ll give you a ton of force going forward 2.) create a rifling guide rail down the pipe to control the rate of spin and ensure it has a nice head start spinning before leaving the barrel. Still it will be wild and uncontrollable but maybe less so
VIDEO IDEA: Since you have a lot of empty Co2 cartridges why don't you use as a tank for solid rocket fuel (for example the sugar one). With cartridges you can get a nozzle simply by going to countersink the hole. The divergent part will be missing, you could perhaps weld, on the outlet of the cartridge, a bolt or any suitable piece of metal and then countersink for make the divergent part of the nozzle.
video idea: since you're having trouble with the nozzles melting, have you looked at lost PLA casting? basically using PLA to print anything you want, putting it in casting material, melting out the PLA then casting the area left be the PLA in whatever metal you want. Probably harder than it looks, but probably more your style since machining isn't really part of your content.
I think Integza mentioned before that casting is too much trouble and the easy aluminium casts can't stand the heat, but still a good suggestion, it's probably the best way to meet the goals with 3d printing involved
From my experience I would recommend 3 holes, 2 for rotation and one in the middle for forward thrust and experimenting with size and tilt of the nozzles.
Video idea: I would love to see this idea of nozzle continued but to try various design use them on a compressed air and water rocket before attempting them for use with real propellants
Idk if anyones mentioned this yet, but im pretty sure the instability is from the fact you only have 2 nozzles. If you had 3, or the designed 4, you'd be able to stabalize it from more points than just opposing sides. Reason for my theory: If their on opposite sides, slight differences in thrust will cause one side to yaw, and that yaw multiplied by roll causes it to tumble out. If you had one more, or 4 like the original, the slight differences could be cancelled out by each other.
i would love to see a video where you experiment with the various physical properties of the ceramic material after doping it with various things like casting epoxy or even just frozen water!
Better way to make the starters without the straw: cut up some ping-pong balls (highly flamable), and dissolve them in some acetone. Then mix the gunpowder in with the mixture till you have a paste. Dip the wires into the solution and let dry. You can dip multiple times to get thicker layer. Works perfectly and no plastic straw needed.
Drop the tomato on a chair with two needles poking through. When the needles enter the tomato, the tomato generates a small voltage. When the small voltage is detected, it ignites a thruster that propels the chair up and smashes the tomato against something. Use slow motion to really capture how the tomato squishes and bursts.
3D print a threaded extension/choke for your barrels. Also, it looked like the bullets weren't going very fast out of the barrel, but then accelerated a lot when they reached the pumpkins. Maybe try something that will give them a higher muzzle velocity - I think that would add a lot of stability.
That was actually by design even with the originals. They had a relatively low muzzle velocity and accelerated once leaving the barrel. The original barrels were more holes than tubes so they had ZERO pressure inside the barrel. You could literally see the bullet in the chamber when it fired and could see through the barrel down the entire length of the barrel.
yeah, but first solder the ignition wire to the front, and run it through the mandrel, which should be star shaped. use the casing for one pole and the nozzle as the other pole. that way he can ignite way more fuel instantly and improve accelleration.
I think the problem is it needs to be smaller than the inside of the casing since it's meant to burn from the inside and the outside. Otherwise it wouldn't burn quick enough.
@@battlesheep2552 Gun cotton but rather than made with cotton balls grind the cotton to powder before nitrating then mix into the rocket candy should give a high burn rate.
I'd change one thing re the igniter, when sealing the straw, I'd seal it with the wire in place instead of having it glued in, would make building the ignition alot faster! Great video tho! Keep up the good work
I'm a fluid mechanics engineer. I think I can see about 3 problems. 1. Your bullets may have an off centre centre of mass due to how you're packing them. 2. They're not gaining enough speed at the end of the barrel. 3. Your narrower barrel is more accurate than the wider. I think that there's a pressure build up in front of the bullet as it travels down the barrel so in order to counter act this, you should cut vents down the length of the barrel. You can see that in the original designs. You can see that when you used a bigger pipe it accelerated more due to I think more gasses being able to vent around the bullet (but reduces accuracy as it can then move around within the pipe). That might solve the second point.
You should try milling nozzles out of graphite! You could do it by hand, but a CNC lathe might make life a bit easier. *Edit:* For anyone interested in recreating Integza's rocket candy from this video, I implore you to do so on a hot plate outdoors, with a double-boiler/oil bath to evenly heat the pan and avoid hot spots, and with PPE-at least eye protection. I'm not your dad, and I don't mean to be the safety police here, but I personally spent New Years Day in a burn ward when I was 15 making this exact recipe on a stove top. Do yourself a favor and learn from my mistakes! *Edit 2:* I also think it would be cool to 3D print parts, give them a surface coating with a conductive paint, and then electroplate them. Personally I've only ever tried this is copper, and it was for art, nothing structural, so I don't know if there are metals with high melting points that lend themselves well to electroplating. And having a thick enough layer of metal to resist melting and oxidation might conflict with the requirement of tight tolerances on the parts. But I thought it might be a cool idea nonetheless. I have also always wanted to see a rocket nozzle with active cooling in a model-scale rocket, maybe with channels through which liquid oxygen can flow. I suppose this would also increase the risk of the nozzle blowing up lol
@@martingarnett9381 Now that you mention it, I am seeing some reports of graphite burning at temperatures as low as 400°C, which is much lower than I had initially suspected. I wonder why it is often selected for rocket nozzles?
@@DaimyoD0 I suppose its because graphite is a good heat conductor, so it would spread heat evenly across the nozzle and redirect it to the casing as well Also the burn rate of graphite would probably be negligible compared to how little time the fuel burns for
Idea: Railgun or Coilgun to launch a rocket payload! Always thought this was a cool concept but I've yet to see it in practice, so I think it'd make a perfect video/series for this channel!
If you re visit this, a couple of things that may help in your design: First, having the nozzle exhaust be connected to a single and clear inlet. In the current design, if the burn begins on one side and not the other, more gas will be escaping on that side, throwing off the projectile. More exhausts. Having seen a breakdown of the Gyrojet, it had about four ports. No process is perfect, but having 4 smaller points of variance helps to balance 2 large points of potential unevenness. another hypothesis for improvement (read: completely unfounded guess) would be to have small, very steep "rifling" exhausts, and a central main thrust exhaust. Mathematically, it may be the same as shallower rifle and thrust ports, but it may help to smooth out any variance in manufacturing. Lastly, weight balancing. If I'm correct, most of the weight is in the back. And so a millimeter of deflection in the back is several degrees of deflection around the center of balance. If the center of balance is far forward, the same back deflection will become a lesser overall deflection in trajectory.
Integza: hey, can I get a plastic straw Clerk: no, those aren’t allowed to be sold here I: what if it is for a homemade bullet, not drinking from C: I: C: I: I’ll see if anyone else carries them
maybe for a second rendition, adding a low angled tri fin into the actual casing might help. have the fins possibly work in tandem with a tapped / riffled barrel or tube to possibly keep the projectile more stable in flight
This was my thought, combined with a breakaway casing to fill the barrel to the walls, and a solid back. That would help with his tumbling "round" issue, as his barrel in this vid was consistantly too large of a diameter.
Next project you can make a metal part with 3d printing by making the model with pla and the cut it bilatetaly in two pieces and then use the moulding method with filling sand/silica around it and compacting it and then take out the two pieces and pour molten metal into it once done join both of the parts (You can also use water soluble filament for complex models)
That was awesome. A way for the projectile to fly is to rifle the barrel and treat the projectile like a sabot. Possibly rifle the sabot to match the rifling of the barrel... That was cool and lots of potential power in projectile.
Hey, on the slow motion footage, you could clearly see that the nozzle didn't quite work, given one of the holes had superior thrust than the other one. Why not to make the bullet "spiral like" to make the air do the job? (Using a one hole nozzle)
The problem is that the fuel isn't igniting evenly or because of the sparkler which I think might still be plugging one of the vents. Another youtuber had tried to improve the gyrobullet and even with more adjustments to make a better exhaust ports they still lack consistent accuracy (one reason they never took off and they aren't good at short range) One thing he DID find that has helped is not to use the central hole style like the original used as well but a flattened sheet that was rolled up but left slightly loose so there is more surface area allowing for more thrust as it can gain more nozzle pressure faster
First of all: again a great video! Video idea: You could try using this self-createdspiral aerospike nozzle from your last video, this would probably give the bullet a more evenly distribution of thrust and at the same time good thrust Also you could make some kind of launching mechanism, so the bullet has a decent basespeed and is oriented correctly when coming out of the barrel (maybe a pressure-loaded barrel with a spiral in it, so the airflow around the bullet is rotating, which rotates the bullet itself) But then don‘t forget to shoot some tomatoes with it ;)
Video idea: I loved to see the recycled co2 canisters so could you possibly melt them in a home made foundry then make rocket nozzles with the melted metal and use 3D printed ceramic for the mold. I think it would be awesome for a learning experience and also a great video. Ps you could also pour molten metal on tomatoes.
A good ignition compound is just some match heads crushed up and mixed with the striking strip on the side of the matchbox. It can be ignited by striking it and works as a bullet primer.
Idea for a future video: You should build a larger spark gap Tesla coil, or a solid state coil (musical?). You could also try Labcoatz’ design. That would be pretty sick!⚡️⚡️
For moving powder around, try just taking a little bit of paper and pinch it right at the centre of one of the edges, to add a "fifth" corner to it, which acts as a little funnel :) We use it all the time when measuring things in chemistry :D
video idea: try doing the gyrojet with a different design, I don’t know if this will work but an idea I had would be to have three openings on the nozzle, one straight and two similar to the original except with a better angle to produce more spin. that way you would still get the thrust from the main opening but you’d also get the gyroscopic balance.
Awesome, I tried this a couple of years ago. I found that having an explosive cap behind the bullet, projected it out so much faster. I still couldn’t get it to fire straight though 😀
@@Humbulla93 that's cool, didn't know it's a gas-less reaction. It react quite violently tho, wouldn't it move at least a bit anyway as reaction to the kinetic energy of the "sparks" hitting the chamber?
Awesome video! For anyone more interested in the gyrojet, Backyard Ballistics did a really nice video recently where he recreated them to pretty good effect.
Love the CO2 cylinder Gyrojet concept. What about fins that spring out and an aerospike nozzle. since the barrel you are using isn't that tight you should have room for four fins that contour to the side of the cylinder and fold out when it leaves the barrel with some sort of spring to put the fins up.
video idea: Tom stanton recently did an electromagnetic launch track build; I suggest you do something similar but use it to launch some sort of bullet or a model plane. (side note: i am a little curious to see if it would work to launch things vertically). Kind of like a mini coilgun or something.
How about making a gunpowder powered engine? Dropping small fragments of gunpowder into the cylinder (s) combined with high compression should work nicely
Re explore this with some different casing ideas as well as some nozzles for different design, maybe sourced from your subs?? Also, I think I could help you with a silicone mold for the fuel!
Video idea: try making a rocket that is just like those ones people make with a PET bottle, some water and a small pump, but trying to reach extreme pressures (and something that would not blow up like a PET bottle)
Video idea!! You should try to make a rocket which will work with some short of "phases" where different engines turn on/off and undock themselves to try and maximize fuel efficiency and distance traveled would be so cool and interesting imo
Video Subject Idea: Making CO2 canister rockets with fins tilted at various degrees to see which angle gave best spin for better flight accuracy different nozzle designs could be good as well. Maybe even see about making a propellent out of tomatoes "since they seem to be flammable". If I had to guess the flammability might come from the sugar content but maybe its something else.
Or maybe have said fins work on a Centrifugal force. So as it spins, if at all, it'll cause the fins to pop out to stabilize. Along with the angling so they keep the projectile spinning thus themselves out from said Centrifugal force. ^_^ (Spiraled groves to start said spin, Centrifugal forced fins to take over as it flies out.)
Aerospike nozzle on the gyrojet but with two slight spiral vanes down the expansion surface to create torque. It will be easier to print and more efficient than the two nozzle approach. You can truncate it to 75% length and have a hole in the center for your fuse which will be glued in and sealed with sliding connectors on the electrical wires to allow separation. This will stop you having to put the fuse up a nozzle and have it blocked.
Well done! I'm really honored you took my suggestion seriously! 😃

You can find KNO3/Potassium Nitrate online as tree stump killer, and most sugars will work fine (altho some may work better than others). Iron oxide is easy enough to find and technically not needed, tho it helps. Prepare your molds before hand! As stated before, overheating this stuff can cause it to ignite! The shape used in the video with the hole through the middle is the most common design in general for rocket motors, if you use a cardboard/reinforced paper tube you generally will not need to demold it, that can be lit with the rest of the propellant.
This should go without saying but make sure you have proper safety equipment, safety goggles, fire extinguisher, clothes that won't catch on fire, etc.
Integza- can engineer and execute his ideas in at a spectacular level-
couldn't think of using a paper funnel for the gunpowder 🤣
I thought the same lol
I think that Itengza wants to escape into space in a huge spaceship, firing back from aliens with jet bullets
Lol
So 40k?
funnily enough, conventional bullets would be way more effective in space. The jet in jet bullets tries to counteract the slowing factor of air drag. Unless you put enough propellant there to achieve a higher max speed than conventional bullet's muzzle speed, but that's basically an RPG, a small caliber won't cut it.
But Nikki "Bugsy" Tesla always said the Aliens were his friends, 👽👽👽
so if we just need small rpg, why don't build a shrinking machine and shrink a rpg :D
That would even be somehow useful 😁
"Who needs to buy a well engineered X when you can make a much cheaper and crappier version yourself?" Story of my life dude.
I missed this when it first came out. It has been a while, but here are a couple ideas to help the rocket bullets fly straight.
1. You cannot rifle the barrel to get a stabilizing spin, but what about the rocket exhaust? A rifled pinhole, leading to angled exhaust bells for the nozzles?
2. Fins and spin are not he only ways to stabilize a rockets flight path. What do a kite and a bottle rocket have in common? Drag. Some model rockets use a similar method for recovery with a ribbon streamer slowing it on decent. A tiny carbon-fiber ribbon attached to the center of the back of the bullet. Roll it up and place in into one of the nozzle bells to maintain the shape of the bullet when loaded. One fired, the exhaust should unfurl the ribbon, causing drag at the back of the rocket and forcing it to fly strait. Using drag alone, you could have 3 streamers placed equidistant around the back of the bullet rolled and placed into a central nozzle. I think they should be 2/3 times the length of the bullet. Should stabilize nicely.
That straw hat in the beginning made me cry. Rest in peace Danny from Taofledermaus. You were a hell of a shot and im glad you got to shoot the gyrojet. You were a uncle to many.
Thank you integza for your video
That looks a lot like a center of gravity issue as well. Adding some weight to the front of the rocket may help immensely. If you look at the original Gyrojet, while it is hollow - the front 1/3 of the round was solid brass.
That’s true of all rockets - mass at the top makes them more stable in flight.
Yes. The CG (center of gravity) must be ahead of the CP (center of pressure) by typically 1 caliber (1 diameter in length). i.e. Add more mass to the nose tip.
@@garyjimmerson3393 And then you get spin stabilised projectiles - where the deliberately make them rear heavy so they turn over on impact… (both the British .303 and all the Japanese WW2 ammunition had this feature).
The gyrojet is one of my favorite forgotten weapons ever produced! Especially the long barrel version. Thanks for making this!
Also, a steeper angle on your nozzles (about 45*) or thrust deflecting vanes on the backend may help solve your stability issues while maintaining the same bore size.
Amazing seeing you hone your low cost techniques and DIY attitude. Can't wait to see more of whats to come!
Cool project, and good humor!
Fascinating, but don't you realize that modifying co2 cartridges is dangerous?
I learned from the best 😂
Cooking his own explosives deflected the "don't do this at home" needle quite a bit more for me...
@@hermanrobak1285 And sealing them in with hot glue. I almost expected him to solder the plastic explosive container closed.
@@jimjjewett the hot glue isn't that dangerous though, there are no sparks to cause the gunpowder to ignite
Driving to work is dangerous too
Integza: *Shows how to literally make gunpowder at home*
Yeah im going to save the recept for gunpowder now
and rocketfuel
well, not like there aren't dozens of tutorials on youtube on making black powder
Shhhs don't tell the youtube mods
@@commandingsteel well, integza isn't in the US as far as i know, so that's all pretty irrelevant? youtube just is quick to hand out penalties for instructions on anything dangerous i think.
Love how you explain everything in detail.
It would be awesome to see two aero spike nozzles set up for the gyroscopic “projectile” . Why? Because i think they look cool.
Or just 1 with fins integrated into the nozzle
Video idea: Use the extra gunpowder to explode a tomato form the inside
edit: I did not explain a lot yesterday, i mean for you to somehow put gunpowder inside the tomato and detonate it (don't know if it needs a container for the gunpowder to work since the inside of the tomato is very wet)
Tomatoes are disgusting!
And since I'm also allergic to Tomatoes you can explode them all!!!
Gongratulations Gokalex! You won a 3D printer! Send me your info (Name, Address, Zip Code, Phone Number) to integza@gmail.com.
@@integza wooooo sent!
I like how you're literally making explosives, and the hard part was finding plastic straws 😅
Welcome to the 3d printed age. This is why they fear "ghost guns".
He's making rocket candy, a propellant. It doesn't detonate, it burns. Explosives don't work as gunpowder or rocket fuel.
Edit: Unless you meant the black powder, which is fair.
Everyone knows plastic strays are far more dangerous than gunpowder, right? ;-)
@@BetweenTheBorders gun powder is still a low explosive, it burns and doesn't dotenate so ""it's fine"" I guess lol
Put a sharp crease in a piece of paper put the gun powder on the folded piece of paper hold the edge of the crease over the straw and tip up until the required amount has been deposited. Great channel by the way !
Great video, as always! Maybe you could try adding nozzles on the side specifically to cause the high-speed gyroscopic rotation (kinda like those Speed Ball fireworks NightHawkInLight did a video on). If you can get those bullets spinning faster, they might travel straighter!
"Honey! The crazy neighbor is firing explosives at the side of our house again...."
But honestly, your projects are all insanely entertaining.
When all your neighbors had to worry about was a ball.
2021: 🚀
Honestly, at this point I'd love to just see you form nozzles out of clay on a wheel (oldstyle) and glaze them. I think you might get better results with way less complication. No porosity, far easier to prototype and I think you'd be surprised by the repeatability. Also, I think traditional glazes would hold up under the temperatures you are looking for.
I’d love to see something similar to lost wax. Print the part, bake it in plaster, then go ceramic or metal.
You can put 3 holes in your nozzle in a triangle configuration rather than 2 holes. That would fix the stability issues and make the rocket bullet shoot closer to its target.
I love the philosophy: if the rocket misses its target, you have to add more pumpkin :)
Try 1.) closing the back of the gun, that’ll give you a ton of force going forward
2.) create a rifling guide rail down the pipe to control the rate of spin and ensure it has a nice head start spinning before leaving the barrel.
Still it will be wild and uncontrollable but maybe less so
VIDEO IDEA: Since you have a lot of empty Co2 cartridges why don't you use as a tank for solid rocket fuel (for example the sugar one). With cartridges you can get a nozzle simply by going to countersink the hole. The divergent part will be missing, you could perhaps weld, on the outlet of the cartridge, a bolt or any suitable piece of metal and then countersink for make the divergent part of the nozzle.
This is super steampunk. Black powder rocket propelled bullets in a gun made from leftover metal.
Couldn't help but imagine the glass blowing up while he was dancing after just saying no sparks
"They were not performing as well as [we] expected"
Just like the real thing...
"This one didn't perform that badly..." [cuts to rocket horribly tumbling from the moment it exits the barrel]
14:16 Okay now it's just trolling him.
'I need you to spin!'
Rocket: 'Okay!' *spins sideways*
video idea: since you're having trouble with the nozzles melting, have you looked at lost PLA casting?
basically using PLA to print anything you want, putting it in casting material, melting out the PLA then casting the area left be the PLA in whatever metal you want. Probably harder than it looks, but probably more your style since machining isn't really part of your content.
I think Integza mentioned before that casting is too much trouble and the easy aluminium casts can't stand the heat, but still a good suggestion, it's probably the best way to meet the goals with 3d printing involved
From my experience I would recommend 3 holes, 2 for rotation and one in the middle for forward thrust and experimenting with size and tilt of the nozzles.
I was thinking 4 holes. 3 to balance the spin, with 1 centered for speed (which is key).
@@DraconicDuelist There is no need to balance, gyroscopic force is more powerful than you might expect. Even 1 hole might work
Whooooooooooooooooooooo, clicked fast than integzas developments in rockets
Video idea: I would love to see this idea of nozzle continued but to try various design use them on a compressed air and water rocket before attempting them for use with real propellants
I’d still like to see you try to 3D print a high-pressure water compressor and nozzle to build a water jet cutter for tomatoes.
Video idea! What siege weapon is the best at launching tomatoes? I want to see a tomato get launched 100mph into a wall by a cannon!
"who needs to buy a well engineered (object) when you can make a much cheaper and crappier version yourself" perfect integza moment
"why buy when you can D.I.Y?"
@@SomeoneTookAK ah yes, the D.I.why
Idk if anyones mentioned this yet, but im pretty sure the instability is from the fact you only have 2 nozzles. If you had 3, or the designed 4, you'd be able to stabalize it from more points than just opposing sides.
Reason for my theory: If their on opposite sides, slight differences in thrust will cause one side to yaw, and that yaw multiplied by roll causes it to tumble out. If you had one more, or 4 like the original, the slight differences could be cancelled out by each other.
i would love to see a video where you experiment with the various physical properties of the ceramic material after doping it with various things like casting epoxy or even just frozen water!
Better way to make the starters without the straw: cut up some ping-pong balls (highly flamable), and dissolve them in some acetone. Then mix the gunpowder in with the mixture till you have a paste. Dip the wires into the solution and let dry. You can dip multiple times to get thicker layer. Works perfectly and no plastic straw needed.
Gasoline and styrofoam works as well. Add some limonene (goo-gone is a good source) and you'll have napalm that spits balls of sticky plastic fire.
Can also use steel wool instead of the wire he was using as it's easily available and works ok as well
Drop the tomato on a chair with two needles poking through. When the needles enter the tomato, the tomato generates a small voltage. When the small voltage is detected, it ignites a thruster that propels the chair up and smashes the tomato against something. Use slow motion to really capture how the tomato squishes and bursts.
The quality of your projects is growing at the same rate as your channel. Gz bro! Thx content
3D print a threaded extension/choke for your barrels. Also, it looked like the bullets weren't going very fast out of the barrel, but then accelerated a lot when they reached the pumpkins. Maybe try something that will give them a higher muzzle velocity - I think that would add a lot of stability.
That was actually by design even with the originals. They had a relatively low muzzle velocity and accelerated once leaving the barrel. The original barrels were more holes than tubes so they had ZERO pressure inside the barrel. You could literally see the bullet in the chamber when it fired and could see through the barrel down the entire length of the barrel.
just add a small kickstarter charge and boom: you got a bolter
How about using the CO2 casing as the mold? A perfect fit everytime and no need to move it.
Cool, I should have scrolled down father before posting the same idea I added some more suggestions have a look :)
yeah, but first solder the ignition wire to the front, and run it through the mandrel, which should be star shaped. use the casing for one pole and the nozzle as the other pole. that way he can ignite way more fuel instantly and improve accelleration.
I think the problem is it needs to be smaller than the inside of the casing since it's meant to burn from the inside and the outside. Otherwise it wouldn't burn quick enough.
@@battlesheep2552 Gun cotton but rather than made with cotton balls grind the cotton to powder before nitrating then mix into the rocket candy should give a high burn rate.
I'd change one thing re the igniter, when sealing the straw, I'd seal it with the wire in place instead of having it glued in, would make building the ignition alot faster!
Great video tho! Keep up the good work
I'm a fluid mechanics engineer. I think I can see about 3 problems.
1. Your bullets may have an off centre centre of mass due to how you're packing them.
2. They're not gaining enough speed at the end of the barrel.
3. Your narrower barrel is more accurate than the wider. I think that there's a pressure build up in front of the bullet as it travels down the barrel so in order to counter act this, you should cut vents down the length of the barrel. You can see that in the original designs. You can see that when you used a bigger pipe it accelerated more due to I think more gasses being able to vent around the bullet (but reduces accuracy as it can then move around within the pipe). That might solve the second point.
Keep at it integza! once you solve the nozzle problem, I'd love to see you take another shot at this
You should try milling nozzles out of graphite! You could do it by hand, but a CNC lathe might make life a bit easier.
*Edit:* For anyone interested in recreating Integza's rocket candy from this video, I implore you to do so on a hot plate outdoors, with a double-boiler/oil bath to evenly heat the pan and avoid hot spots, and with PPE-at least eye protection.
I'm not your dad, and I don't mean to be the safety police here, but I personally spent New Years Day in a burn ward when I was 15 making this exact recipe on a stove top. Do yourself a favor and learn from my mistakes!
*Edit 2:* I also think it would be cool to 3D print parts, give them a surface coating with a conductive paint, and then electroplate them. Personally I've only ever tried this is copper, and it was for art, nothing structural, so I don't know if there are metals with high melting points that lend themselves well to electroplating. And having a thick enough layer of metal to resist melting and oxidation might conflict with the requirement of tight tolerances on the parts. But I thought it might be a cool idea nonetheless.
I have also always wanted to see a rocket nozzle with active cooling in a model-scale rocket, maybe with channels through which liquid oxygen can flow. I suppose this would also increase the risk of the nozzle blowing up lol
He mentioned graphite himself, too. I wonder (and have no idea), how graphite works with excessive heat. But it seems to hold up well(?)
Graphite can handle extremely high temperatures, but will burn if exposed to a flame.
@@martingarnett9381 Now that you mention it, I am seeing some reports of graphite burning at temperatures as low as 400°C, which is much lower than I had initially suspected. I wonder why it is often selected for rocket nozzles?
How did it catch on fire when you where cooking it? Was it over a open flame?
@@DaimyoD0 I suppose its because graphite is a good heat conductor, so it would spread heat evenly across the nozzle and redirect it to the casing as well
Also the burn rate of graphite would probably be negligible compared to how little time the fuel burns for
Idea: Railgun or Coilgun to launch a rocket payload! Always thought this was a cool concept but I've yet to see it in practice, so I think it'd make a perfect video/series for this channel!
If you re visit this, a couple of things that may help in your design:
First, having the nozzle exhaust be connected to a single and clear inlet. In the current design, if the burn begins on one side and not the other, more gas will be escaping on that side, throwing off the projectile.
More exhausts. Having seen a breakdown of the Gyrojet, it had about four ports. No process is perfect, but having 4 smaller points of variance helps to balance 2 large points of potential unevenness.
another hypothesis for improvement (read: completely unfounded guess) would be to have small, very steep "rifling" exhausts, and a central main thrust exhaust. Mathematically, it may be the same as shallower rifle and thrust ports, but it may help to smooth out any variance in manufacturing.
Lastly, weight balancing. If I'm correct, most of the weight is in the back. And so a millimeter of deflection in the back is several degrees of deflection around the center of balance. If the center of balance is far forward, the same back deflection will become a lesser overall deflection in trajectory.
Integza: hey, can I get a plastic straw
Clerk: no, those aren’t allowed to be sold here
I: what if it is for a homemade bullet, not drinking from
C:
I:
C:
I: I’ll see if anyone else carries them
maybe for a second rendition, adding a low angled tri fin into the actual casing might help. have the fins possibly work in tandem with a tapped / riffled barrel or tube to possibly keep the projectile more stable in flight
This was my thought, combined with a breakaway casing to fill the barrel to the walls, and a solid back. That would help with his tumbling "round" issue, as his barrel in this vid was consistantly too large of a diameter.
Next project you can make a metal part with 3d printing by making the model with pla and the cut it bilatetaly in two pieces and then use the moulding method with filling sand/silica around it and compacting it and then take out the two pieces and pour molten metal into it once done join both of the parts
(You can also use water soluble filament for complex models)
That was awesome.
A way for the projectile to fly is to rifle the barrel and treat the projectile like a sabot. Possibly rifle the sabot to match the rifling of the barrel... That was cool and lots of potential power in projectile.
Hey, on the slow motion footage, you could clearly see that the nozzle didn't quite work, given one of the holes had superior thrust than the other one. Why not to make the bullet "spiral like" to make the air do the job? (Using a one hole nozzle)
Yeah that's what I was thinking
I think it wouldn't work at slower speeds, so when first fired and when accuracy is affected the most, it has the least effect
The problem is that the fuel isn't igniting evenly or because of the sparkler which I think might still be plugging one of the vents.
Another youtuber had tried to improve the gyrobullet and even with more adjustments to make a better exhaust ports they still lack consistent accuracy (one reason they never took off and they aren't good at short range)
One thing he DID find that has helped is not to use the central hole style like the original used as well but a flattened sheet that was rolled up but left slightly loose so there is more surface area allowing for more thrust as it can gain more nozzle pressure faster
I thought a single nozzle with fins integrated into it for the spin work work well and be fairly easy to do
Such a good teacher!
First of all: again a great video!
Video idea: You could try using this self-createdspiral aerospike nozzle from your last video, this would probably give the bullet a more evenly distribution of thrust and at the same time good thrust
Also you could make some kind of launching mechanism, so the bullet has a decent basespeed and is oriented correctly when coming out of the barrel (maybe a pressure-loaded barrel with a spiral in it, so the airflow around the bullet is rotating, which rotates the bullet itself)
But then don‘t forget to shoot some tomatoes with it ;)
Bro those rounds are absolutely *massive* for even a rifle.
Video idea: I loved to see the recycled co2 canisters so could you possibly melt them in a home made foundry then make rocket nozzles with the melted metal and use 3D printed ceramic for the mold. I think it would be awesome for a learning experience and also a great video. Ps you could also pour molten metal on tomatoes.
I'd love to see a *jet powered potato!*
Kind of like this project, where the projectile is rocket powered, but clashed with a potato cannon!!!
3:16 mmmm, forbidden chocolate
A good ignition compound is just some match heads crushed up and mixed with the striking strip on the side of the matchbox. It can be ignited by striking it and works as a bullet primer.
video idea : use the same gyro bullet from double barrel and smash tomatoes and pumpkins ,Happy Halloween
Idea for a future video: You should build a larger spark gap Tesla coil, or a solid state coil (musical?). You could also try Labcoatz’ design. That would be pretty sick!⚡️⚡️
Build a fallout inspired "mini nuke" launcher that uses some form of rocketry to launch it. That would be an awesome video.
Agreed
I like that great idea
For moving powder around, try just taking a little bit of paper and pinch it right at the centre of one of the edges, to add a "fifth" corner to it, which acts as a little funnel :)
We use it all the time when measuring things in chemistry :D
video idea: try doing the gyrojet with a different design, I don’t know if this will work but an idea I had would be to have three openings on the nozzle, one straight and two similar to the original except with a better angle to produce more spin. that way you would still get the thrust from the main opening but you’d also get the gyroscopic balance.
Awesome, I tried this a couple of years ago. I found that having an explosive cap behind the bullet, projected it out so much faster. I still couldn’t get it to fire straight though 😀
Rifle the barrel with the same spin/twist rate as the nozzles.
Just wondering what would happen with thermite instead of gunpowder🤔

Awesome video! For anyone more interested in the gyrojet, Backyard Ballistics did a really nice video recently where he recreated them to pretty good effect.

@@Gabriel-yd4bq ah damn shame
@@Gabriel-yd4bq that’s bananas. I’d hate that more than tomatoes if I were him
Love the CO2 cylinder Gyrojet concept. What about fins that spring out and an aerospike nozzle. since the barrel you are using isn't that tight you should have room for four fins that contour to the side of the cylinder and fold out when it leaves the barrel with some sort of spring to put the fins up.
I think there are shotgun slugs that work like that
spring out fins on explodeing slugs I mean, not rocket propelled
That's some of rhe best homemade black powder I've ever seen!
What about a Tomato-Rocket™?
video idea: Tom stanton recently did an electromagnetic launch track build; I suggest you do something similar but use it to launch some sort of bullet or a model plane. (side note: i am a little curious to see if it would work to launch things vertically). Kind of like a mini coilgun or something.
How about making a gunpowder powered engine? Dropping small fragments of gunpowder into the cylinder (s) combined with high compression should work nicely
Has been seriously tried in the early days of piston engines.
As you can imagine, didn´t work out well.
"who wants to buy a well engineered gun when you can make a much cheaper and crappier one" makes for a nice motto! I think I'll steal this from you
Re explore this with some different casing ideas as well as some nozzles for different design, maybe sourced from your subs?? Also, I think I could help you with a silicone mold for the fuel!
Video idea: try making a rocket that is just like those ones people make with a PET bottle, some water and a small pump, but trying to reach extreme pressures (and something that would not blow up like a PET bottle)
He could reinforce it like a COPV
Video idea!! You should try to make a rocket which will work with some short of "phases" where different engines turn on/off and undock themselves to try and maximize fuel efficiency and distance traveled
would be so cool and interesting imo
Best quote in the entire video:
"I need those rockets."
Video Subject Idea: Making CO2 canister rockets with fins tilted at various degrees to see which angle gave best spin for better flight accuracy different nozzle designs could be good as well. Maybe even see about making a propellent out of tomatoes "since they seem to be flammable". If I had to guess the flammability might come from the sugar content but maybe its something else.
Or maybe have said fins work on a Centrifugal force. So as it spins, if at all, it'll cause the fins to pop out to stabilize. Along with the angling so they keep the projectile spinning thus themselves out from said Centrifugal force. ^_^ (Spiraled groves to start said spin, Centrifugal forced fins to take over as it flies out.)
Why don't you make a rocket power plane.
Cause he is integza, not tom stanton LoL

Aerospike nozzle on the gyrojet but with two slight spiral vanes down the expansion surface to create torque. It will be easier to print and more efficient than the two nozzle approach. You can truncate it to 75% length and have a hole in the center for your fuse which will be glued in and sealed with sliding connectors on the electrical wires to allow separation. This will stop you having to put the fuse up a nozzle and have it blocked.
