- In this video I show you how to build a simple jet engine from scrap, and it glows red hot! I made this videos as I got many requests from comments and e-mail. Feel free to comment if you need help with your engine.
The engine classifies as a valveless pulse jet.

If you made a jet engine like this, please link video of it here. :)
Are you serious 🧐 there's no engine 🤬🤬 wast my time
@@night_mode97 This is a simple jet engine.
@@night_mode97 you are also wast of time...
NOOB
@@night_mode97 it is a real jet engine, just maybe it doesn't produce enough thrust to move itself and there's no constant fuel supply, so it stops after a short time (but it can be simply modified).

Can you put something like this on ice?
It works beautifully. Funny how a tiny thing can make so much noise
Thats what "he" said
Sounds good tho suprisingly.
Used to think the same thing when my kids were born 😂
You can build V1's now and "BLITZ" the UK.
I wouldnt try that. They put a giant rubber dome over London. It'll bounce right back at you.
Remember to yell “Allah Ackbar” and the mayor of London will call it part and parcel of living in a big city.
@@JohnCamp brilliant
Yup.
Thumbs down are from Boeing and airbus employees
Because he made a pulsejet, not a turbofan
Theyre just jealous cuz this doesnt require windup rubberbands.
their just jealous
@@pressyprice
Nah. It's just that they're going to overwind the rubberband one of these days.
Instructions unclear, my fart can ran off to london and is getting chased by some spitfires
And then the fuel runs out...
Sounds like a rotary engine startup
the ignition at 2:43 was ASMR.. what nice sounds
I think I have videos where the ignition lasts way longer than that
Really creative and really good for the basic knowledge of jet engine. Really cool
I am satisfied only from your this video in whole you tube...thanks.
I'm totally flattered
Same
Thank you, somehow I now understood Pulse-Jet engines
No problem, that's awesome to hear! I hope you start building them too!
Caught me at fart can. Great laugh gets you a great thumbs up regardless of the following content. Thanks for the Video. It was well done.
Now that’s amazing, but serious this is really cool
2:30 really cool how the smoke shows the air funneling into the engine
Nicely built Pulse engine
Simplicity at best
Pulsejet engines are *LIT*
It sounds like my maverick when it's trying to idle!
I'm unsure. Are you mocking the legion of petrolhead fans out there who love the sound of gasolene gone wild? It sounds truly fabulous - a wasp gone dizzy on high octane fuel. As a long time (l'm 47 and I've failed to grow up) fan of your videos, I'm not sure if you're mocking the petrolhead community by calling it a fart in a can.
As farts in cans go, this is beautiful. Fuel, ignition, harmonics and the simplest yet most powerful bwaaaart available. In lockdown sir, I salute you
They do sound like a fart from a distance
ua-cam.com/video/7Ydv9Ef-99I/v-deo.html
this is SO cool dude
Good work
The reason the can is getting red hot is because of how thin the walls are. I’m sure that if you used water pipes instead the engine life would be much longer
Thin walls allow more sufficient cooling if you would pour water into the walls. Without cooling a thick wall will run slightly longer but is harder to cool down.
A video that shows a way of cooling that works.

And here's a thick walled engine that was hard to cool down.
ua-cam.com/video/3TrOOzipB8s/v-deo.html
Very good.
Great video man!! I made mine in less than 10 minutes. If i get it to last a few more seconds I'll make a video🤙
same mine doesn't run more than 10 seconds
Any chance I could get a can length / diameter / exhaust length ratio u found to work best? I cant get mine to run more then 5 sec at most
Do you know some video/image/article that explains how it works exactly? Thank you for the video. I'll use it in a Physics project on my university.
It works so that the flame goes into the jar and burns all the air, which creates a vacuum that sucks more air, and it ignites again.
@@Fileeraus also inertion of air inside the exhaust tube is important - it keeps moving after explosion ends, so there's resonance (like mass on a spring). Exhaust fumes in the tube are blocking air access, so it can be taken only through the right hole. So this pipe must be long enough to make the engine work.
You should put a turbo on it 😂💪
Awesome
Cool
Would it work with a larger reservoir directly beneath it? If so, then with a reed valve at the front, it might me suitable to power a free flight airplane model.
If you want to power an rc plane, you should look into proper pulse jets. These spray can jets are merely artificial and don't have much potential to move even the engine itself. Here's one that I made:
ua-cam.com/video/k6-g5to5VN4/v-deo.html
@@Fileeraus time to prove you wrong.
I will 100% make a Pulse Jet Engine from Tin Cans or (Work Shit). Work shit is stuff you find at work. I work a job I can fuck around in as long as I tend my customers when they show up.
So I’ll be walking around a find a spray bottle that’s broken. Take the tube out. Find old paint cans. Etc. Bars of metal or pipes.
I’ll make Something up.
@@shadowdeslaar A proper pulse jet with combustion chamber made from a spray can will implode before it moves on its own. ;)
@@Fileeraus worth it. At least itll be a nice fire. And plus can try to upgrade it. They make steel Cans. Well. The ones we sell are.
@@Fileeraus when you say Proper. You mean like a V-1 rocket engine. Right?
Cause so far I’ve got a Gravity Feed Liquid Fuel Can on top.
(Of course not touching).
I also ended up adding a hole to one end of the Can. (Using a pop can).
I added a Exhaust Hole and Fuel Intake.
Now gonna see what happens.
(Probably gonna add a second cam inside the man one, creating a Pressure Chamber). If lucky the pressure won’t be enough to blow or implode but enough to sustain firing.
Mahtavaa! Tässä on sitä ”tee se itse” meininkiä :D
Jaa täällä on suomalaisiakin
@@codjonnet617 Juu onhan videon tekijäkin suomalainen :)
@@nipafilms236 oho en huomannutkaan :D
Sounds like a lot of bees/wasps in heat. 😎😄
Angry bees
Simple and awesome!
gonna try in my garage and spicy things up a bit
Sounds good! How are you spicing it up?
That last engine is like the thermojet
Yep, the model resembles thermojet. I think its called thermo-jam
Do you have to use heet gas treat?
Lmfao you tripped on the can. That shit literally made me laugh.
A few questions, what fuel did you use and was it gasoline. If it was gasoline how did it now just explode
Time to make this tommorow
Edit: my neighbors came over out back and were impressed by this creation
Hyvä video suomi! :D
Kyllä! 👌 kohta tulossa lisää pulse jet toimintaa
Make the same thing out of stainless steel, add a fuel injector, then your set! RC pulsejet!!!!
Hey sorry to bother you what size is the intake hole for yours mine will run for a little right exhaust but it cuts out and will not run longer than 10 seconds also I use heet as fuel
heet it's antifreezing for cars?
I cant wait to make this during the apocalypse 😂
During the apocalypse, fuel for this engine will be hard to obtain
@@Fileeraus yeah, you're right. But it would be cool as heck to mount a jet engine to the back of a motorcycle.
Pulse jets are the best as they sound like a broken car
hey I think I sealed bad the exhaust pipe and it's failing do you think it's that? greetings and I wait for your response
Sounds like a drag racer muscle car
Does it produce decent thrust? I need something where you can see the airflow over a surface. (I want to slap a aerospike nozzle on it)
Yes it does
if you blow air into it whiles its running does it die or fire it up?
It dies
This inspired me to make a jet engine and I ended up with a steel can about the size of a big hairspray can jb welded to a .5 inch galvanized pipe that won't really run on its no matter what you give it I'm currently running 99 percent isopropyl alcohol but I have this electric Balloon pump i use for air and I get my jet screamin and literally glowing doing that. What this guys can does is nothing compared to mine. The first time I ran it on alcohol the paper just vaporized.
Blowing air into it makes it just a bunsen burner. Also, for some reason I've had bad luck with aluminum cans. Also make sure that the exhaust is sealed well, try my method and maybe add your jbweld to make it extra sealed.
@@Fileeraus I can hearing pulsing but with to much air and to little fuel it does that also the jbweld on mine cooked off its dust and it's not together anymore but I'm about to spend some money investing in a bigger jet on propane and I don't plan to have to give it air
@@clips1166 Something like this or a valved jet?
I've tried to run this tin can jet with propane without success.
ua-cam.com/video/k6-g5to5VN4/v-deo.html
I have tried to make three so far and I have only been able to make it start for a second or two...any suggestion for sizes (can,intake,exhaust)
how long is your pipe? 1m should be enough,
My hole is just as big as a pencil
can you manage rpm or it can only be at idle? i judge a srynge or some sort of tiny model pump will do
It doesnt generate rotational force, just a very tiny ammount of thrust, I would imagine if you took a spray can of something flammable and sprayed it in there then it should increase power, good luck!
Thank you so much my car can now make it up and glide over hills seamlessly, I have a 10 in tube for my pulse rocket engine and the cops don't like me for some reason
Just a tip: If you decide to use RC racing fuel and a thin can, put a wet towel on it so it doesnt melt.
It wont melt but it helps to cool it and it will run longer
does it produce thrust maybe for rc aplication?
Not quite enough
can you make this so it can move on its own power?
EDIT oh wait i know why you put bricks and stuff on it.👍👌
it cant really not enough power
I replaced the fuel with oil and it works the same as from the video
Thank you man, I learned a lot from this video. I did take more of an improvised approach😂. I used a whipped creams bottle as the combustion chamber and a metal pole from an old mop. It’s tricky to keep going sometimes, (probably because I’m using a different fuel, isopropyl alcohol) and also because the weather is pretty cold. What do you think?
Edit: Also, it can be tricky to start (sometimes). It also runs for like a couple seconds. Maybe I made the intake to big, I would say it’s big enough to fit your ring finger through or it’s the fuel because methane doesn’t burn as quickly.
Try mixing it with gasoline
@@Fileerausthank you so much bro. It ran for more than triple the other times.
@@Fileerausjust got a run for like 30 seconds !
@@Fileerausyou think it could create thrust by modifying it somehow?
@@Fileerausmaybe by adding a nozzle or narrowing the exhaust end?
You should stick a leafblower in the end of it
Why on earth
Tried to build one but I can't seem to get it to work, I think I made the intake port too big which sucks cos it means I'll have to get another whole new can
New can to the works then
I have a quick question, does the exauhst pipe need to be this long?
It can't be too short, but it can be longer no problem. You can try with shorter but it might not work as well.
Just a simple question, how much thrust?
0.00000000000000001
Can I add a fan or leaf blower or compressor to the intake so it can run longer?
You don't need additional air, if you can make fuel feeding system, then it can run longer.
@@Fileeraus I made it but it would pop then sometimes stay lit for a minute, but only make any noise when I blew air into it. If it matters I used nitro rc fuel. I also noticed the metal tape on the exhaust, does the pipe have to be sealed, or is a bit of gas/exhaust leaking ok
I used foil tape to act as a bit of sealant on the exhaust, so yea it needs to be sealed. Try again when its sealed and if still not working, maybe make the intake hole a bit larger
when it stops running time to call the tow truck
How fuel?
"back when I was young"
What all fuels can I use for this ?
Basically anything flammable the key is in the hole in the front and pipe in the back. It’s just a siphon that uses combustion instead of gravity to create the low pressure
Does it actually produces thrust ??
A little bit, but not enough to move itself. Also this design has thrust in both ways.
I tried it. I used a shorter in height butane can and a fatter exhaust (as well as a wider intake hole). I used ethanol for fuel and it didn't work. I am not sure if it is because I am not getting the fuel air mixture right, my intake and exhaust ports are too big or small, the can is too short or the fuel I'm using is wrong. I even made a hole on top and put a spark plug to spark there but that wouldn't ignite the fuel
Note: It has been a few months now, comment says 3 months ago its more like 4-5. I am thinking of making a second version and start out with smaller intake and exhaust holes, ethanol as fuel, no i am not planning to use gas. If it works, I will try to put a carburetor on the intake hole and attach ethanol fuel lines to it. Choke wide open, because this thing will probably need way more air than a normal engine. Plan is the carburetor will provide fuel so the engine won't stop after a minute or so because the fuel in the can is burnt. Also, hopefully i will be able to control the throttle. Not sure if the carburetor idea will work though, since it might not have enough compression (and it doesn't) to suck in fuel via the venturi effect. I don't know how much air you need to send through the carb to make fuel come out so. Wish me luck, if i ever get my ass off this chair and actually go do it
Try to make the intake hole smaller or larger and also uae a long exhaust pipe
I`ve tried to recreate it. But it only runs for a few soconds.
I think it breaks down because it´s getting too hot or. How can I match the length of the pipe and the size of the hole?
well it's a pulse jet engine and they aren't easy to create. Maybe your hole is too big?
I made one as well and it does the same thing. When I used a long pipe and sealed the hole better it worked fine. And I'm using metholathed spirits as fuel
@@xXrandomryzeXx Yes, i think the hole was too large. In the next days I will try it again.
Right dude , where you get the exhaust and how big is it (length)? Ik im late to the vid
Also how wide should the intake be
Do you think I can use pure ethanol as fuel? Also what do you think of creating a fuel input so you can add more fuel while it’s burning
Yes, go for it! I've seen someone use a syringe to inject fuel
Have you tried to propell anything with those?
I have not, but it can be done. I focus on long runs and overall performance :)
I made this but I tested 3 length of pipe: small(2’6”) medium(3’3”)and large(4’10”). The small and medium pulsed but stalled out after 2 seconds but the large doesn’t want to start. What length should I use?
Intake size is more critical. I have around what your longest pipe was
@@Fileeraus oh I see
I made 2 differenti engines One with a smaller can and One with a bigger One but they managed to only give 1 cicle before shutting off any suggestions?
Possibly too small intake, or too much fuel
Hey what cans did you use what brand were they and how long was the pipe and how wide it was?
Paint can and brake cleaner. Pipe is 1.4M and width is 1.6cm
Thank you
Does it make any thrust
It does make a little thrust
does it produce any thrust
Yes, it blows hot air from both ends
Hi i build one and it works but just for a fue secunds and i dont no wat is the problem. So please help
This is amazing , I want to try and make it but I am unable to find the exhaust pipe , is it possible to run it without it?
And i am not allowed to use fuel as I am only 16 but I have some old Diesel laying around can I use it instead .
And can I use any other similar metalic tube for the chamber ?.
Sorry for troubling you with these novice questions.
Thanks
This model will not run without the exhaust pipe. Diesel will not work. You can make the chamber from something else but it still needs a pipe for exhaust, this video just shows the engine made from bunch of scrap basically.
Also, you can go to some car parts store and probably find all kinds of fuel alternatives that they probably sell to you
Okay thanks , also can you please explain the function of the exhaust pipe , and why the exhaust gas can't pass through the hole in the end .
And what length should the pipe be ? Is 25cm okay?
Thanks absolute love your channel
@@tanishqreddy5617 The engine ignites itself from exhaust gases and they need to be collected in the pipe. 25cm is quite short and probably will not work.
Okay thanks a lot
@@tanishqreddy5617 no problem, I like to help anyone who watches my videos
Does it have to be a spray can or can it be any metal cylindrical object? Like a soda can?
it can be anything, but other metals found in household like aluminum will have a short life.
do you need the exhaust tube to run it?
yeah
No
I try to make the pulse jet with a paint can. He start but just 2 or 3 secondes. The size of hole can have an impact for the running. (sorry for my english I am french ;)
You should make a small hole first and make it larger during testing
@@Fileeraus OK so if it start but just 2 second, it might the hole so big.
Or too small. How fast does the engine rev? Also you might have a compression leak in the exhaust pipe
@@Fileeraus It is indeed a leak in the exhaust pipe. I didn't think it had an impact on the engine
@@lucashulot172 If you don't mind spending some cash, you can use car exhaust repair gum to seal the exhaust, or use foil tape around the pipe.
Can i use rubbing alcohol as fuel?
Sure, but it contains water so it doesn't burn as good as other fuels.
lmfaaoo i also burned down my whole garage there was even fire on my shoes 😂
Get a bbq piezoelectric igniter and *boom* you have an engine with no need for external flame to start it
wow thats simple af damn im gonna make that today :)
I want to see the results ;)
how do you figure out how big the hole has to be and how long the pipe has to be
its a bit of a problem with the one i built
Pipe length is not critical, just make it long enough. Intake hole you adjust larger until the engine runs good. Make many tests before you enlarge the hole.
Sounds like a buzz bomb.
I wonder why 🤔
Does it have any useful thrust?
Not really. Its so low that the engine won't move itself. Also this design has thrust both ways lol.
@@Fileeraus well,the smoke seems to get into the entry hole... Maybe it has thrust only on one side ;)
It first sucks air in, the combustion makes thrust from the intake and then a vacuum sucks more air and the fuel ignites again. This happens several times in a second.
Toimiiks tää iha perus bensalla myös?
Joutuu kikkailemaan että saa bensalla toimimaan, mutta on mahdollista. Ensimmäistä kertaa kannattaa käyttää Masinolia.
How long should the exhaust pipe be
Mine is around 1,5 Meters
does it still work if u add a fuel injector?
it can work with fuel injection, I've tried to get this run on propane but no success yet
does it produce thrust?
Yes, just a little bit
Is it powerful enough to move anything? Is it possible to put it on a scooter or perhaps a bike?
Not really, the materials weigh more and it produces thrust in both ways. (Officially not good)
If you want power, look into these designs.

@@Fileeraus Thanks!😃
I sense Colin Furze energy here
@@David-gk8yg Yep, you're sensing true things😂
drill a small hole and put a wire tube and squirt more fuel inside it will run longer
I've been trying to find something that would allow me to spray propane into the jet
Now you can fix this in your bicycle and a fueal line in that .
Any other fuels that will work?
this can work with anything flammable, but use something that is close to 100% of the flammable fuel. I mean deodorant or hand sanitizer won't work good
@@Fileeraus ok thanks
I didn't this with a gas can when I was a kid. It shot across the ground and set a wooded area behind the house on fire. Needless to say my ass was set on fire later that night lol.
Hey can you give some dimensions so I know what I'm workin with? I wanna make one when I get back to my shop on Monday, just wanna know some starting dimensions so I can scale it up or down to how I want. Thanks!
When scaling the dimensions don't matter. Just adjust the intake hole until its right
nice.. can i do it with tall aluminium can like from some energy drink?
I haven't found success with aluminum cans.
@@Fileeraus ok thx... I'll try a few things.. If some of them will be successful I'll let you know :D
Is it possible for this to melt due to the heat?
No
can you use different fuels?
Yes you can, try out everything. Note that fuels like diesel won't work as it needs to be atomized to burn.
@@Fileeraus not necessarily, maybe it would work with a wick burner? It has many fibers to get large evaporation area in small space.
What is flowing trough the pipe? Air or fuel?
Exhaust gases, so air
How much pressure does it out out
7, maybe 7.2
