3D Printed CO2 Pool Torpedoes

- We all know that you can build CO2 rockets and CO2 dragsters, but what about using CO2 under water? When I was growing up, torpedoes were a big feature in movies, TV and video games and something about them fascinated me. Now that I’m all grown up, I decided to make my very own CO2 powered torpedoes that you can launch in a small space like a pool. After a prototype design that proved the concept, I settled on a three piece 3D printed design that houses a 16 gram carbon dioxide cartridge as well as ballast to keep everything traveling smoothly. Printing takes about six hours for the torpedo and another four hours for the launcher. The torpedoes are launched by a device with a spring loaded nail that pierces the seal on the CO2 cartridge and sets the torpedo on its way. These things are great fun! Down the track, I’m going to look at altering the launching system to fit a radio controlled vehicle for some underwater battles.
The torpedo won't harm anyone, but be cautious around the launcher (sharp object) and CO2 gas (high pressure and cold)

These are *A LOT* of fun! What would you do with them?
These do look like a lot of fun by themselves!
But as you said, it only gets better when you mount it to a an RC model. Can't wait to see what you do with these! Loved the video!
I'll tweak the fin design to a spiral, to achieve some kind of stabilization
Isn't that pollution?
harass the wildlife at the local lake
I would fill them with high explosives and have a scale submarine battle
I think something that would make these much better is by making the nozzle/exit a smaller diameter. This would make a lot more thrust and make the torpedo move much quicker.
in theory, you're right..but limited by 3d printed plastic ..depending on quality but it will just explode instantly due to extreme pressure if u want make smaller nozzle
It would explode if the gas could not get out quick enough
@@danielcarpenter9935 I understand that PLA Plastic has its limits. But also the nozzle diameter could have been made a lot smaller. When you look at the video the diameter is huge which is why all the gas releases so quickly and why it doesn't go fast or far. I understand a tiny nozzle would totally destroy the plastic however
Just get some metal tubing. You can make a bell reducer just by getting two different sizes. One to be threaded to the co2 and the other that’ll fit snug inside the threaded pieces so you can solder it. You’re not limited by the plastic in 3d printing. Your creativity can work passed that
I don't think that's right though is it? Say the canister holds 500psi. If you make a smaller orifice you'd still have 500 psi but pushing on a smaller area, hence less pounds of thrust. It's a tradeoff, more pounds for a short duration, or less pounds for longer. The ideal diameter would depend on the weight of the object and how streamline it is
It would be fun if you collaborated with Integza to create a version 2!
It looked like you had a lot of liquid co2 belching out the back of the torpedo. I suspect a smaller firing pin hole and an expansion chamber would improve the thrust. These would decrease the amount of co2 expelled and allow the co2 to expand to a gas before coming out of the nozzle.
I was thinking about mounting the cartridge closet to the front to provide ballast and also make room for an expansion chamber as well but the weight variation after emptying it would throw the balance off. Maybe find a sweet spot toward the center but I was definitely thinking a smaller hole and an expansion chamber into a kind of necked down exhaust port kind of like a rocket nozzle as well. This is way too cool.
@@eamonia Maybe a bath bomb warhead to balance it?
The classic method to gas power a torpedo is to use a turbine and propeller assembly so the gas pressure is used more efficiently. I myself would not be able to resist the lure of designing such a thing!
also if you printed a water inlet after the expansion chamber, the gasflow would accelerate it out the back and thus create more thrust.
@@Culpride I concur. A well designed venturi, possibly following or combined into an expansion chamber/heat exchanger, could massively increase the propulsion efficiency, and thus probably the range. Also, relocating the canister would leave the total system lighter, translating into even better acceleration and efficiency.
A little torpedo hystory for you:
Prior to Pearl Harbor, most torpedos were launched underwater. Any torpedos launched by plane (airborne) would have a very high likelihood of jetting off some direction, and this meant you needed to fly very close to ships if you wanted a chance at hitting them. This made them unfavorable. Leading up to Pearl Harbor, Japan had been engineering torpedos and ended up with a torpedo called “the type 91”. This had modifications to help it’s initial drop to be more stable, and for the torpedo to be at a certain depth. This made it so they were hard to see because they’re underwater, but also kept it at a depth that would strike the ship’s hull.
Even just adding fins along the torpedo’s shaft (more near the tip) it would give the torpedo much more accuracy when firing.
I read somewhere the first torpedos were launched from shore batteries at the entrance to harbors. The propeller was driven by a coil of wire. The wire was uncoiled back to shore by a steam engine. How crazy is that?
@@iguanapete3809very crazy
The raid on taranto cerca 1940: Am I joke to you?
@@iguanapete3809 actually you’ve got that confused with modern fish. Back in WW2 the torpedo ( bear in mind I’m using the German G-7 series as I understand it’s workings very well) was predominantly mechanical in nature and was descended from the torpedo developed in the late 1890s by Whitehead. To arm it the con would call down range, angle on bow and depth settings. They turned a big wing nut at the front and a little propeller would measure the distance ( minimum arming distance was preset at 300 meters to protect the sun from a misarming fish). The G-7A predated WW1 and like the whitehead torp ran on steam. Upon being shot out via compressed air or sensing the fish hit the water the water would enter through an inlet and something would activate and immediately produce steam to drive the turbine hooked to the propeller. The G-7A had a rather long range but did produce the distinctive white “ bubble” trail which could be seen and avoided. The G-7E introduced later in 1941 was all electric. It had a shorter range owing to batteries and a lower speed but produced no trail. It was best used during daylight or stealth attacks. The G-7E also introduced the magnetic influence detonator which they later added to the A model’s warhead. It worked like a magnetic mine, once close enough to a ships magnetic field the warhead would detonate right under the hull creating a giant void of water and slamming the keel with enough pressure to crack it. It was usually only good on calm nights or harbor raiding where the waves couldn’t bother the depth keeping of the fish. Until the US MK-37 torpedo introduced in the 1960s they used the straight running steam powered MK-16. Even the Whitehead fish that sunk the Blucher in Norway weren’t attached to shore, they were free swimming. Anyways the MK-37 introduced the trailing wire. A multi mile long pair of thin copper wires that connects the weapon to the launching submarine. This allows the sub to control the torpedo and lets the torpedo use the subs own sonar for its attack. The MK-48 of today still uses the wire ( hence the term “ wire break” ) you can disconnect them and a MK-48 is smart enough to find its own way to the target. The MK-48 is also not battery powered either, it runs a small internal combustion engine and runs on “ Otto fuel” this is needed to give it its long duration( over 30 minutes once launched) and it’s high speed ( needed to sink the faster Soviet attack submarines of the Cold War) the MK-37 had speed limitations that could allow a sun to evade it long enough to cause it to self destruct. ( the battery run MK-37 is also suspected of suffering a battery fire which detonated the warhead of one of the torpedos aboard the I’ll fated USS Scorpion )
Torpedo just means naval mine. Most torpedos throughout history have just bee gunpowder barrels
Might want to try adding a twist angle to the fins and try to spin stabilize them and reduce porpoising. Awesome video, thank you so much for making the files available!
Rifled fins was something that I thought of it.
I don't think that will work, because the instability is always going to be towards the surface of the water, not a deflection due to differing resistance. It'll help it go straighter left/right but not up/down very much.
That might make it go out of control like spinning in circles or curving
No I totally agree putting a twist in the stabilizers will definitely help from purposing
i tried and it made in cuve alot uncontrollably (very random) and slowed it but 2nd attempt gave it a controlled curve but still slowed
That first print time lapse was so satisfying, absolute perfection!
Would love to see a gas-turbo propeller drive version
why not make a version that has a some but not to much explosive the shink a paper boat
@@Benneth12 firecrackers?
How to carbonate your pool.
Cool project, very inefficient design but for a swimming pool that doesn't seem to limit it. It's cool you made it as simple as you did rather than chasing perfection and ending up with an overly complicated final version. I (and apparently everyone else in the comments) have ideas to improve it, but the simplicity of yours is excellent. It just works.
Underrated channel. Great videos and a lot of effort all well shot and edited. You'll pop off eventually. (Underwater cam update please love that video!)
Thanks! Im enjoying the ride! I’m having a break from water related projects over winter here, so I don’t have an update on the underwater cam right now. I’m focusing on a fast project on tarmac right now though!

I'm more amazed at the tools it takes to make things like this; the ease at which it can be done. As kids, even youg adults we settled for sling shots made from a Y in the branches of trees, a metal tube with a fire cracker in one end and a marble in the other for cannons. Oh we had a blast, but the toys they have today...I'm impressed. I suppose I shouldn't call them toys. It's probably not as hard as I think it is to build, but I don't know how well I'd do with the technology of running a computer. I guess I'll have sit back and enjoy watching young people work magic...great job. Oh yeah, back in the day a kid could buy all the firecrackers he or she wanted. What stopped us most of the time was not an authority, it was money. We simply didn't have the money. It was under a buck unless you got the real good ones... for a good pack of BlackCats it was about 75 cents. I can't wait to see what you have next.
GREAT BUILD! Super creative dude!
0:55 rockets typically have a diverging nozzle to extract maximum work from the high pressure. That might help you get more thrust. Later in the video you can see how the gas continues expanding after it leaves the torpedo.
Really like your Video 👍
I think if you were to integrate a venturi style nozzle it would help the torpedo to travel farther.
A small nozzle for the co2 to escape and 4 holes to suck in water from the outside. With the smaller nozzle it would also result in less co2 consuption to enlarge the distance even more.
Also if water was to rush out the nozzle it would have a load more thrust.
Ya beat me to it - I was gonna suggest the same thing...
Another thing he could do is to angle the fins more, so the torpedo spins more as it moves, to increase accuracy.
Awesome video
It’s always nice when a print comes out clean.
Mate why isn’t this channel bigger than it currently is, this video and your content is awesome! Subscribed!
Thanks and welcome!
I found one of these in my mums wardrobe before but it didn’t float
💀
Uhhh i think thats an adult toy
😂😂😂
Jimmy bill bob I think it’s time for me and your mother tell you
😧
It’s almost like the concept of the “Gyrojet” pistol, but applied to Torpedoes!
3:08 I love the reference! Probably one of the best lines from Bones on Into Darkness there is!
This is such a neat idea! Awesome video, man.
That space inside the torpedo could be used to store an elastic band or a spring.
You could probably get it to go further.
Or a few grammes of TNT ;)
I think if you would use a internal propellor to drive an external propellor in the back, you would get much mor range, especially if you let the exhaust gas vent throug holes around the tip making a gas shield so its not in direct contact with the water.
That looked fun to make. I really am impressed on how you design and print the parts. Look forward towards the next project.
More to come!
This brought me back to when I was moving from Victoria to QLD when I stopped at Holbrook to see the submarine a truly amazing experience
It's a great place to stop!
that is awsome
If you incorporate a nozzle into the design (as used with rocket motors) you can get more speed and distance out of it.
Honestly really cool. I remember as a kid buying a set of plastic rubber torpedoes and just tossing them around under water. They would build momentum really fast just because of weight. More weight faster movement. Also I can see the practical uses in this case. Say your operating an ROV and need to tag a fish. This fish is big and fast so you shoot it with a GPS torpedo and essentially track it for research purposes. Or if you need to track a vessel because they are smugglers you can use a drone ROV with magnetic torpedoes and stick to the side a little GPS tracker. Or if you need to send a camera lure in a tight spot you can't normally send a camera. Just shoot the torpedo cam and control how far it goes with the winch.
Or maybe 3D print a submarine that just operates off CO2 gasses. It would look like a spear the C02 channels are 3D printed with 100% infill to ensure an air tight fit. It may be best to use a material that can be a little elastic. Then set it up with tiny vales that will open and close to allow for fast acceleration under water. Maybe a seeker mine instead now that I think about how this can work. Essentially if a vessel gets too close it activates seeking the vessel and explodes on contact. Or just sticks on like a leach. Useing magnets. Then a signal would be given off to a satellite that would alert the ship that a sub or vessel is in range of their vessel or base.
Usefull for underwater labs.
I know I'm late to the game on this one...but here we are! I was watching this video and my brain was screaming at you. "Why aren't you launching them from UNDER the water!?" Doing so would maximize the performance as the torpedoes would already be surrounded by the water and not have to fight through that moment of trapped air between the nose and water that is created from the transition from air to water (Or in short....less cavitation). That's why the torpedo tube on a submarine is filled with water first before firing. And with these being gas-propelled, less gas would be wasted in the initial "ignition" or launch. Also working with different nozzle sizes would help like what has been suggested by others below. I think your plan of launching them from below your RC catamaran is going to really help with the performance of the torpedoes.
Great video. Definitely subbed now.
An idea I had when doing Robosub was to use an impeller and prop to effectively gear down the gas. Maybe you could make one go 100 yards like that.
This honestley seems like it could have been a toy in the 80’s
not wrong
thank you for sharing this with us!!!
This is great! Lack of stability came from small fins and your cg likely behind your center of pressure. This is awesome though. Great work
Now you just have to find the best nozzle design. That would be a dope collaboration with someone as Integza
I would like to see a version where an impeller is implemented. I think it will help you get a better range due to the fact that it should provide a torqueing motion in the water which is similar to the torqueing motion of a bullet that has been passed through a riffled cylinder.
They have the job of producing a stabilizing rotation, which the fins on the tube already do. Might even reduce range due to additional drag
making a much bigger torpedo powered by a regulated paintball tank powering a turbine engine driving the props would be the closest to the real thing as you could get. A regulator would allow for longer run time as well as lowering the pressure so you dont destroy your moving parts.
So thankful for this
I remember being able to buy CO2 cartridge piercers for models back when I was a kid. You could control the hole size with an adjustment.
Sounds cool.
It would be interesting to see this with a smaller nosal and I'm having a thought about hypersonic torpedoes, they put out a bubble right in front of the torpedoes so it's actually pushing thru air at the front .
Cool project 😎
Thanks for visiting the museum and gaining some inspiration. We love to encourage learning projects like this and would like to collaborate at some stage if you wish.
Friends of Holbrook Submarine Museum Development team
Thanks for watching! I always suggest to anyone that stops off at the Holbrook sub to also check out the museum - it's very impressive. There have been so many suggestions to build a better torpedo, so if I make a follow up video, i'd love to collaborate. Thanks for all your time and effort.
If this hasn't already been said I'm surprised.
Once the design is complete, it would be cool to see it on an RC plane too.
Torpedo Hall of Fame at the Naval War College Newport, Rhode Island the best. Excellent brass clockwork examples there.
i'd love to see a revisit of this project to add a depth keeping mechanism, though I imagine the space and weight requirements for that would require a significantly larger torpedo (and likely a different propulsion mechanism)
would be funny to just re-run the development of the torpedo in the back yard ending with functional acoustic homing torpedoes
I have *SO* wanted to do this exact project for years... Some actual torpedos are ejected from the tube using compressed gas... so an enclosed launching tube might be a cool modification to try.
Great idea.
Very cool. Nice work.
Damn that's the best use of a co2 cartridge I've seen
Simple and fun!
I'd love to see a carbon dioxide propeller driven torpedo. Just use a turbine impeller on the gas side and a regular propeller on the water side. Then you just take the excess carbon dioxide and dump it overboard to give even more thrust. You might need to install a regulator though. You're probably going to need a bearing planetary gear system. Also torpedoes should be nose heavy
Pretty sure any such construction would likely blow up from pressure alone. Consider how much pressure on holds. You would need to machine it from metal to have even a chance and use least one of those commercial regulators to limit the flow, witch point it becomes too heavy and cumbersome to work in this scale. Far as i recall torpedoes use pressured air only to push the torpedo out from the launch tube and then electric motor kicks in. Speed of the device builds up cavitation that is used to make it faster, but this also makes it noisier hence everyone in 100km range knows you launched a torpedo and even larger range know if it hit something or self destructed.
I agree, at the the scale such mechanical devices would fail. Buuuut a induction jet could be a delightful thing ;)
I was thinking the same thing, using parts from a dental drill
Gran trabajo,muchas gracias!!!!
Great video! Loved it!
In version 2, make sure to try out firing under water to see if the mechanism has the power :)
For the next version, swap the CO2 cylinders for NO3 cylinders (nangs) and add a tube of wax to the outlet to create a solid/gas hybrid rocket with way more thrust. You could add a wick to the wax so it burns just like a normal candle until the NO3 is released.
Way back in the day there were balsa kits for small boats and cars using this propulsion. The biggest problem was, no nozzles. If the striker punched the hole in the CO2 cartridge off center (which it almost always did) the vehicles went way off course. The nozzle effect of your design, with a striker that is probably more precise, is quite an improvement.
Now, movable fins and gyro stabilization. . .
man this video is so high quality and interesting and I was suprised this is such a small channel
Great job! I'm curious about the way they're launched, it looked like it was always from above the water pointing down. What would it look like if they started underwater? I'd think that they would have more gas to use for propulsion since the CO2 expands more easily in the air than in the water, so you probably lose more of it while the torpedo is still in the air. But that said, I could also see how flooding the "firing pin" tube would slow down the nail and could make it more difficult to pierce the cartridge. Is that why they were launched this way?
Spot on. Ideally, I would have launched them underwater, but the launcher wasn’t powerful enough to get the job done. That’s something that I need to work on for my future plans though. Oh, but also, it was fun ‘shooting’ them into the water!
Fellas
Its gaming time
The bubbles are so cool!
Dude these are the coolest pool toys ever and I need Japanese long lance versions!
I have already found a way to integrate it into a model TBD devastator, this is gaming time
You could adjust the weight so that when the co2 is gone the torpedo rises. That would make it easier to get it out of the water.
i cant belive this man puts this up for free, perks for that m8
Bro this is actually awesome
Never occurred to me how perfectly balanced a torpedo must be. I suppose it is just a glorified water arrow lol. I do wonder if you'd get a straighter flight (?) path with a bigger rear stabiliser. Seemed like the ballast was just about right, it was just a tad unstable. Very fun project!
I'm sure that you could achieve a more stable trajectory with some serious stabiliser redesign.
torpedoes weren’t just for stuff like this, they had to be accurate to be able to sink ships without any faliure.
Heck yeah, what a cool project! Looking forward to see them mounted on your boat. Do you think the torpedos would still work decently if you attached an action cam to them? Would be amazing to have a first person view haha
I actually strapped an Insta 360 Go 2 to a torpedo, but those shots didn't make it into the video. The drag was too much for it and it didn't do much of anything. Thanks for watching!
@@electrosync Very cool that you tried tho!
great editing and video, keep it up
Thanks for watching!
For your next design, I suggest a shape similar to the torpedo pool toys. You pimply push them and they cut very fast thru the water. The pool toy uses a design that mimics the natural shape of a fish. The shape literally pushes the object thru the water. Add co2 power and you'd have a fast and stable torpedo.
To make them flow faster and further you could also make it have some more body curve then just a straight tube.
Most pool torpedoes will have this Bottle like shape and and generally go quite a distance with a light throw
.
also re working the fins to be a little larger can add plenty of stability.
Could you make some sort of 3D Printed Pneumatic Engine / Turbine (and maybe vent exhaust gas for remaining thrust?) based version for more endurance, or at least sustained propulsion? Could even collaborate with the various channels that have made designs for engines/turbines etx!
Either way, amazing this was an design, and great video!
I’m sure it can be done - the efficiency would be the tricky part to get right. Thanks for watching!
Combine that with an expansion chamber so it goes to a gas form and there you go, a true torpedo with full range.
@@electrosync Even an inefficient turbine with some expansion chamber might be more efficient (especially if the exhaust is directed backwards to aid in thrust) than just gas straight out the back. The tricky part would be getting it to be small enough to fit. Probably something simple like a paddle wheel and a prop and then eject the exhaust out the back. if you made the design a tad larger you could fit more but that might defeat the purpose, Just using a small paddle wheel turbine that approximates a pelton wheel might be enough.
Yellow one had a little cavitation on the nose that made it go up. Very nice now build a sub for these.
This is awesome!
Imagine if u made like a battleship and tried to sink it with these torpedos
Very nice video. The project looks fun, but you miss an important part: The explosives ;-)
Noooo! This project already seems dangerously close to a pipe shot gun!
Incredible engineering 👍
I usually just nerd out looking at this sorta stuff, but weirdly all I could think with this one was how dangerous that launcher/piercing mechanism is. With the cap being so close to the edge of the cartridge, the nail really doesn't need to be long enough to pierce a skull, 5mm or so should surely be adequate. For version 2.0, as well as for possibly added stability, I would suggest finding a nut or similar threaded thingy that matches the end of a CO2 cartridge and using the soldering iron trick to embed it in the very end of the torpedo. that way the foil cap will actually be accessible to a very small piercing device.
Yea uhh how much money for these?
I don’t know
I think the specific impulse is too low for a co2 rocket pushing through water. You might use to the Bernouli principle to place water inlets before the nozzle. Water will get sucked in and mixed with co2 and thereby increasing the exhaust weight.
those are so cool good job! :)
This looks great
Just as with model planes, the control surfaces should be larger proportionally. Also the length of the torpedo seems very short compared to its diameter. That would influence the directional stability.
Me wondering when he will make a Co2 powered plane"😐"
Interesting project
this feels like an OG The King of Random project!
Add intake openings around the fin area to allow the C02 to suck in water and accelerate it. This would improve thrust and help to warm the C02 and increase expansion. Like a venturi effect.
You might get more stable shots if you launched them under the water. Probably lose less thrust to the atmosphere (escaping co2 at puncture) as well. Just my thoughts but very well done!!
An underwater launch would also remove the gas/liquid transition that occurs when the nose goes from forcing gas(air) out of the way evenly across its entire face, to liquid hitting the bottom of the nose asymmetrically and setting up a harmonic wiggle.
I was thinking that too. I couldn't figure why he only launched them in the air at an angle into the water.
Super cool video! If you ever decide to revisit this video, one thing I haven’t noticed in the comments was the air pocket that the torpedo creates at the front end. I believe this is acting like an airplane wing, lifting the nose out of the water. The only way for the air pocket to be sustainable like that is by a very low pressure on top of the front of the torpedo, meaning the pressure imbalance will cause the torpedo tip to rise. See if you can design a way to eliminate that air pocket! I suspect it is caused by being launched above the water.
You could put a little bit of potassium nitrate mixed with sugar and wood chips in the nose with a fuse of a few seconds in the centre. You could have battles with mini ships as you would have torpedoes with mini warheads. Perhaps the scratch plate from a matchbox could be used to ignite the fuse on launch
Banana For Scale
Of relevance to this topic is a video about implementing automatic Depth Control on a Lego submarine (th-cam.com/video/KLEH8RJsYgI/w-d-xo.html).
They basically encased a Lego sub inside a clear acrylic tube and used a servo to compress or expand a large oral syringe (20~40ml) thus changing buoyancy; a sensor was used to determine depth through the acrylic. About 1:50 in is the where the depth control gets shown.
When I was a kid, my dad and I built a launcher for CO2 tubes. It was just 3 feet of old metal broom handle pressed into a wooden base with a nail in it. Drop the cartridge down and it hits the nail. With a little luck it will shoot into the sky
wish i could design stuff to print. Beautiful job
why did you make the torpedo any longer than the cartridge itself? curious cos it seems the added space up front was the issue as it adds buoyancy and you had to add weights which would slow it down
I could have designed it to be shorter, but I wanted the looks to be faithful to a real life torpedo. I didn't test a shorter torpedo, but I think you'd probably run into stability issues.
@@electrosync I see. thanks for the response. enjoyed the video and am looking forward to your future projects
