Integza is competing with Electroboom to see who can put his skeleton into orbit first.

By using metal with holes, you're essentially making a... Swiss knife.

I like the idea that you went, "not a fan of this plastic spinning next to me. I think ill stop." But you were just playing with hydrogen and oxygen in a shared line. As someone whose accidentaly caused a small explosion in that same way, that made me fucking nervous.

The duality of man's inclinations for technology: Can we make war with it? Or can we make food with it?

Tbh i would have liked to see more of the hydrogen with compressed air and experimenting with that cuz invisible fire making a red hot knife is COOL. cool video otherwise

a bit disappointed to see you accepting a sponsorship from temu :(

Alright, now that you've made a knife, we need a flaming sword

Another material that looks just like the 3d printed porous knife, is the air mufflers/diffusers on industrial pneumatics. Under magnification, some of them look like brass beads that have been heated and pressed into a truncated (blunted) cone shape. If Integza wants an off-the-shelf porous material, that has pipe thread already attached, I would use the pneumatic muffler method. I just checked the industrial supplier McMaster-Carr here in the USA, and I see they even make stainless ones.

A 3D-printed knife with a billion tiny hydrogen rocket nozzles in it is just too appropriate for this channel lol.

I've never feared for you life more than the moments i watched you hold a knife with a supersonic gas output with a flame front that was traveling back to the source.

A sword version of this with only half of the blade burning would be a terrifying weapon. Keeping the fire a half a meter or a foot and a half away would be a big improvement for the user too.

It would be awesome to see a 3D-printed old-school cannon that shoots cherry tomatoes 🍅 or 3d printed projectiles using the rocket propellants you previously created. I'm also curious if you could add rifling in the barrel and show the difference between with or without it. Would it be too hard to make it with a 3D printer? Missing some explosions lately ❤

A TEMU-ad.... Would have preferred a Raid-Shadow-Legends app over TEMU

As a guy who bakes bread, I love the idea that a bread company is trying to be as high tech as aerospace companies.

Mans just casually makes a lightsaber when testing a jet engine theory, Fucking sick.

The repellant feature is awesome! Propeller and boat hull would make a low friction and perhaps efficient boat.

I love when someone looks at one problem and realizes it's actually a solution to another problem they have.

The most incredible thing in this video is that he did all of these INDOOR. In a somewhat closed room.

Next logical step is a Star Wars style light saber using plasma and magnetic fields to contain and shape the plasma.

The transition from the crazy ass balloon popping to the calm professional talk

That hydrogen and oxygen experiment was a 50/50 chance of never seeing Integza’s neighborhood ever again.

Video idea: You should make a video collaboration with NileRed, where you turn tomatoes into rocket/jet fuel!

Integza: Fearlessly holding a flaming ready-to-explode red hot knife without gloves on. Also Integza: Hides under the table when running a tiny motor. Be bold, my man. Integrate the death motor with the flaming dagger of death 😆

I'm not into aerospace myself, just admiring all the engineering, but I LOVE this chanel. I've watched 5 videos nonstop, bro is cooking

Not temu sponsoring the video 💀

This concept has been in use in high-performance (military) jet engines for more than a decade. They don't use it for fuel injection, but rather air cooling the rear turbine blades. Turbojet power density increases with combustion chamber temperature, but past a certain point no existing materials can withstand the heat. The solution was to bypass some of the air from the compressor section through tiny holes in the rear turbine blades to cool them well below their melting points, minimizing turbine blade creep.

"I'm a big fan of bread, but my true passion is jet engines." -Absolute poetry.

The video was awesome. I was a little worried about your ceiling in a couple of those shots though. Anyway I am an aircraft technician and totally agree with you. I can't wait to see how you incorporate it into a jet engine.

Cmon, even a RAID shadow legends sponsor is better than Temu

4:30 nah bro, he enchanted his knife with fire aspect

Fun fact, a lot of people don't know but Royal Kaak has a motto for their bread company, it's - "Put Kaak in you".

Imagine a thief breaking into his house, seeing that flaming knife lighting up in the dark

Please no more Temu😢

I was thinking that I would love to see a fan driven, Nitromethane liquid rocket engine. With an aerospike nozzle, so it looks like the blackbird's engine. Great video.

You should make a "hot/ cold" house fan, make the blades out of your new porous metal 3D Print all the casing but have hydrogen source pumping into the fan blades so when it ignites you can have hot air or switch it off and have cold air. Major dangerous but watching you wave that knife around with fire all over the place. I'm guessing danger is your middle name. Keep up the good work. Have been watching you for years

I can't believe we've looped back the internet to see integza do the 1000 degree hot knife videos

That is so cool! I tried making a flaming sword once by casting aluminum over a tube that ran down the length of the tube, then drilling through the edges of the blade. It was a bad design.. for a lot of reasons haha. That works so much better and you can still use it like a knife!

That knife is so cool. My guess is that the side of the jet engine that you don’t want fuel to go to will have to be printed slow and the side that you want fuel to flow through will be printed faster. Thanks for sharing this with us.

I am honestly impressed you haven't burned down your house yet.

I don't believe for one second that you actually use TEMU to get anything.

You're thinking too small. You MAY be able to create not just a normal jet engine but a DETONATION engine. The trouble with detonation engines as I understand it is the combustion mixture comes into contact with a hot surface or hot gas and ignites before the detonation flamefront reaches it. This technology might be able to provide a forcefield of constantly incoming cold (and yet unmixed) gas that prevents this contact from happening. Just like bread dough sticking to a knife.

A “lightsaber” with this tech and sufficient fuel tank would be pretty awesome.

Integza really be roleplaying as "THE GOD OF LONDON" in this video

a temu ad? really? i really hope they paid you very very good

Okay so the coolest part to ME was that it "Self-Cools". Air is a super good Insulator, that's why Insulation is often just very very porous materials or Fiber's of something. So, when the knife is burning something without an oxidizer, it would probably never get hot enough to damage itself. BUT when you add a little more "Power" with the oxidizer, it get's Red-Hot and the SECOND the oxidizer is gone, it self-cools and stops glowing. To me, that is incredibly cool!

Bro this video is one of the more dangerous videos on yt.

i don't know if anyone has suggested this, but try to create a rig for the knife you just made that spins the knife while it's rotating at around a 1000 rpm, and figure out the optimal rotational speed and gas injection pressure to create a literal flame wall... !!! props if you can do this with a long bar instead of a knife... this would be a good concept to start working on the jet engine tbh.... if the fan design can literally spew fire and rotate fast enough to suck in enough air, you have what you want.. :D if you like my idea, please conisider sending me that 3d printer... i would be absolutely thankful.... i don't even want it for free, i'm literally willing to pay what i can afford on my end to have one !!! living in a third world country is absolutely shit, can't find good deals anywhere and even if printers are available parts are missing that make it impossible for me to get it in my city in working condition...

Disappointed that integza accepted temu sponsor

I don't get a chance to mess with aero engines too often, but I do work rather frequently with large gas turbine fuel systems at my engineering job. They've been using diffuser-type reverse flow fuel delivery systems for a while now with pretty interesting results! I highly recommend that you look up the General Electric DLN 1.0 combustor system sometime, Integza. Its an older design from the 80s but in terms of flame stability in high-flow combustion its really quite impressive, and being older a lot of the documentation is freely available online.

Dude that screeching is called flashback. U could end up an exploded smart guy who had a good idea but was not smart enough to install a flashback arrestor in the fuel line.

You looked like a kid in a candy shop already and then you come in with "you know what would be more intense? If I tested it with hydrogen." 👏🤣

he literally made this sponsorship like "hi thanks for ur money temu im gonna maka a sarcastic ad for u" I LOVE THIS KIND OF IRONIY

This is the perfect activity to do indoors

you don't understand how much i wanna grab that knife and turn the pressure to max then just watch it go super saiyan in my hands

Integza: *makes fire knife* Also integza: “lets make toast!”

ouch, a Temu ad. it's really time for creators to start vetting their sponsors properly.

uff Integza.. An TEMU Ad? big oof on that... -.-

this video was like watching an unhinged Beakman from Beakman's world given free reign with dangerous science to build future weapons for some industrial complex

You can also try doing a somewhat thin rocket nozzle that goes al the way to the end and returns to the center, cover all of it but the very center ( or end, for the nozzle to cool with the hydrogen) with coating the outside with metal so that the pores to the atmosphere are closed functioning more like a pathway for the hydrogen to pass by, just like the actual rocket nozzles, u can cool your nozzle while distributing fuel. These micro pore would probably work perfect

"okay here's the bread, i am going to turn on the knife." words you never thought you'd hear from Integza 🤣

Glad to see Integza get back to his roots: almost lighting his ceiling on fire with unchecked open flames.

Next video: attach a fireworks tip to a rocket and let it fly into the sky and explode 🙃

I am amazed your house didn’t burn down.

I am excited to see what you come up with. As a 50 y/o retired Army officer I am blown away by the level of sci-fi that has become reality. There are even some technologies that I used in the military that have not become public yet but they have SO MANY possibilities. I love to see what happens when someone with a high IQ thinks outside the box and changes the world for everyone!!

Not Temu 😭

Is it a bad thing that I was on the edge of my seat watching you eat an entire dinner meal on camera? haha. I see the potential this tech has, and fully expect you to expand upon this.

14:14 nick looks proud of the world he influenced

My friends and I made potato launchers using a PVC tube with a combustion chamber on the end. We'd spray in an accelerant, close the chamber, and spark the liter we'd glued into the wall of the chamber, and send the potato flying into the distance. I know your space is limited, but this device shares commonalities with a rocket engine, and could be used to propel tomatoes at high speeds into stationary objects to pulverizing effect.

Electroboom: "Finally, A Worthy Opponent , Our Battle Will Be Legendary!"

Bro made a rare fire knife skin IRL and an ultra legendary SUPERSONIC FIRE KNIFE SKIN

I remember back when rocket scientists were smart and didn't try to do every highly dangerous thing all at once for the admiration of randoms strangers they will never meet in life.

Integza -“ yes I’d like to get a quote on home insurance?” Agent - “ wait are you the guy with the fireball knife and rocket engines?” Integza - “ …. Maybe… “

Video idea: "A jet powered leaf blower" Dont know if its possible, but also the option to spit flames and burn the leafs😂

Integza just casually playing with a pretty big flame indoors is giving me anxiety :D

You need a longer HANDLE made out of CERAMICS :) A sword variant is obviously the next step...

So basically you made a religious knife, since it's holy.

You should add a thermally resistive ceramic handle with a guard so it doesn't get to hot.

Brings whole new meaning to "like a hot knife through butter"... and bread, and cheese... HAHA!

To be honest, it might be a good idea to make a plywood box to cover that compressor and catch the explosion when you're around other people haha.

Today, I watched a video of a guy cutting and eating random foods with a hydrogen powered rocket knife.

Make a flaming broadsword that takes 2 cartridges in the hilt for a flame out the end!

That was awesome! I hope that you get it through security so I can see it at Open Sauce!

Who ever insures any of Integza's home/ property, liability, life, health, neighbors is the real legend here.

Oh my goodness... This is awesome! So here is a thought... Instead of a combustion chamber that pushes air... Push water... With hydrophobic coating on the wall... Then hydrolyze the water to browns gas... The browns gas can pass through... The water cannot and the water can be circulated as a better coolant for the combustion wall...

I swear, your channel is a near constant barrage of super interesting forays into jet engines but this video was completely novel and exciting. Thank you for showing us this kind of stuff (and I'm happy for you that you get to do this, too)

This channel has been such a good source of reference for 3d modeling post apocalypse weapons

this is really going to reignite the 1000 degree hot knife videos

I kinda wanna see you make a Warhammer 40k Melta gun. Which is described as a compact jet engine (rifle size) that is used for melting through naval ship doors and even tank armor in short ranges.

How to make ion jet thruster..? Idea is to make a jet engine combined with a ionic thruster to suck air. Thruster will suck air into combustion chamber and in combustion chamber it mixes with fuel and burn to produce high velocity gases and boommm this idea may work...

you should try to make a pulse jet engine out of the porous metal, you could seal the outside of the metal body to make sure all the gas only going inside the engine, this would allow for even spread of the fuel throughout the engine and possibly make new and very efficient engine. (from there you should put it on a rocket and launch it up to see what happens)

You're really planning on bringing a weapon to San Francisco? Not just any weapon, but a literal flaming knife? Oh boy... good luck.

If you get a lean (oxygen rich (air rich)) mixture going into the blade and run it for a few seconds then the metal should get hot enough to ignite the mixture within the knife leaving fully combusted exhaust, and the heat will be focused on the blade instead of making a huge 3 foot torch, so you could toast bread better You'll want to turn down the flow a bunch to keep the blade from melting You could also drill a hole through the handle, and insert a pipe to seal off leakage in the handle, and increase transmission speed/capacity to the blade

I'd love to see a video that explores other unconventional uses of 3D printing, and the potential they hold! So cool that all this came from a hiccup in the printing process!

the fire knife cheese melting would be an amazing thing to see at a restaurant

Can’t wait to have everyone carrying flaming swords in the future

For a future video see if you can 3D print a battle axe or a sword with the same material and then put them to the test in some epic sløw mo shots.

ladies and gents this is what a mad scientist looks like

Bro just turned a science vid to a flaming knife cooking show

I think it'd be interesting to see you tackle all those "free energy" devices seen all over the internet. May not be as explosive as your usual subjects, but I'd love to see how you tackle the subject with your humorous style!
