"Looks like glaze you put on cake" I would have gone with something else but okay

Put tomato concentrate into the resin, then you can use the blood of your enemies as rocket fuel

"Don't smoke" he says while burning plastic in an enclosed space with no respirator xp

2:11 so close. Accidentally almost called them what they are - - Sparklers.

"Sparkler" is the sparkly thing you put on birthday cake. love the video

There are few ideas for improving hybrid rocket that I have. 1. You could incase whole solid fuel and nozzle in metal pipe of some sort, that would allow you to increase the chamber pressure that intern would speed up the exhaust gas that would produce more thrust. 2. If you know the energy density of your plastic filament and burn rate you can increase specific impulse (ISP) by controlling valves using Arduino and a stepper motor connected to the oxidiser valve. 3. You could make a nozzle from 3d printable ceramic resin, that would allow it to survive longer exposures to high temperatures and could be reused, also if the outer casing is made from steel pipe nozzle could be mounted on flex joints that allow it to gimble, but that is only after the problem of caring enough of oxidiser to power engine and also not too heavy for it to be able to lift off. Few tips that might help from my own research and experiences while I was active in our rocketry club before whole covid and all fun that came with it :D Use standard off the store pipe for the outer casing, you can easily drill through the end cap and fit nozzle and also use a high-temperature sealant for no high-temperature exhaust escaping around the nozzle and starting to eat solid fuel pellet/core. because we are engineering students we have all the tools like lathes and mills so it was a bit easier to weld and centre so we didn't have out of centre thrust. but you could also 3d print a centring guide for drilling in the centre of an end cap of the pipe. If you need help with calculations just send me a message on discord :) boksininkas_LTU [KARAS]#6196

it's criminal how under-subscribed this channel is, he is like a mad rocket scientist from the movies. so glad youtube recommended this to me.

As a type 1 diabetic the joke @ 4:32 was freaking hilarious! Thumbs up from me sir!

Serious concerns alongside a video idea: ABS is extremely toxic when burnt. There's a reason why most commercial ABS printers are enclosed and why many people who print ABS encourage building printer enclosures. And that's just melting it. You're burning the ABS and that's releasing even more chemicals into the air. Secondly, I'm pretty sure that your current test stand has way too much friction and way too much mass. Though your printer's linear rail prevents more friction than is necessary within the context of a 3D printer, that's still a lot more friction than necessary. And your rocket mounting method (aka a huge, heavy clamp), means that the moving portion of your rocket has a *lot* of inertia to overcome in order to actually move. These two things together meant that you have a massive wall that your rockets have to pass in terms of force before any movement will be shown at all. If you were to build a system that has less mass on the movement axis and lubricated your rail or replaced it with something that moves smoother at lower forces, you'd see significantly more movement on your rocket tests and be able to judge differences in speed, etc. far more easily. Thus video idea: combine both of these. Build an outdoor test stand designed specifically for testing your rockets. I know you hinted at something like this in the video, but I think you could make an entire video re: your process of building a test stand that is safe (health wise), smooth (rail wise) and light (mass / intertia wise). And the result would also be better, more visual test results for the rest of your videos!

Align your rocket vertically with your rail. By keeping the rocket next to the rail you are actually producing torque on rail because that thing wants to spin.

Me at the start of this video: Man he must have a special fire safe room for this testing Me at 11:06: Is that a wooden roof?

"those things you put on birthday cakes" are actually called sparklers and I have never seen someone put them on a birthday cake, the're usually just waved around at event with fireworks such as fourth of july or sometimes a new years event

The most ballsy thing about these experiments is the lab location - under a wooden roof xD

I have a theme for a future video: upgrade your gas setup. For starters, you *NEED* a ball valve with a spring-close mechanism for each type to be able to quickly turn the gas off. (Pull the lever to open the valve; when you let go, it slams closed *instantly*.) You also need a more solid way to mount the cylinders and controls, so why not make a complete solution based on a toolbox? The cylinders can rest in the bottom and the levels/gauges/etc. can mount as a control panel in the tool tray. (The hoses can be stored in the lid, so the toolbox can be closed up with everything in it.) That way, you can have the whole thing completely portable, yet quickly set it up whenever, wherever you need to. You can even take it on the bus without being asked pesky questions.

The editor version of you giving the other you in the past an idea is just glorious!

your channel has grown so much since i first started watching your videos! great video as always! keep up the amazing, unique work and high charisma

might it be an idea to use a ball valve so that you can shut off the oxygen faster and you don't burn down your attic?🙃

VI: try building a desktop fusion reactor Tomatoes are disgusting!

Love how this guy tries his best to make his videos funny and understandable by also trying his best at English. Keep up the good videos.

Estes vídeos são incríveis. Fico contente que há um canal português com tanta qualidade

"Keep burning." "But we're out of-" *I said we burning today*

Almost every time, when I starting to watching video on this channel I think: "Nooo... It can't be! He can't do this" But at the end of video: " He did it... Again!" :))

What? A Portuguese channel like this? Love it!!

the "sparkley things" you put on birthday cakes are called sparklers. very creative

You’d benefit using some sort of intermediate valve between your fuel source and the flame. I say use a oxy/acetylene cut off torch for the ability to not only mix two gasses, but also have the ability to have the fuel sources on and off instantly.

"one of those sparkler things you put on birthday cakes, I dont know how to say it in english." Sparkler, you got it... its just... sparkler. lol

ce amuzant esti, nu mai face glume de astea ca ajung la spitalul de nebun. ms

You should coat the plastic with fireplace sealant and carbon fiber. The fuel would be able to continue burning with no leaks and it would be fast to make.

Try to do Lost PLA casting. You 3d print an object, bury it and sand, and pour molten metal. The molten metal will vaporize the PLA and replace it resulting in a metal version of the 3d printed object. There are also wax filaments manufactured intended for this process.

Let's all just take a moment to appreciate the fact you're building highly flammable rockets in the attic of what I assume is your house. And wasps bother you more than accidentally burning a hole in the floor 😁

Man !! you are one step away from changing human history of rocket science

Tuga ta em todo o lado, continua com o bom trabalho

Video theme idea: creating an underwater propulsion machine. Or building my own DIY rocket engine thrust measuring device (I actually have a good idea on how that could be built).

My mom likes nasty tomatoes, how can I convince her to stop eating fruit from the deadly night shade family? You could try using a composite metal filament. The kind you bake out the resin and then sinter it in a high temperature inert gas ore reducing oven. Hmm maybe you need to build an oven first. I have seen people use a kiln like yours but had it like a Russian nesting doll with one segment full of charcoal to prevent oxygen from getting to the part. Maybe you could use tomato based charcoal? Codie's lab has some nice videos that are related to this.

Youre freaking awesome glad I found your channel

How have I only just come across this channel!! It's amazing

"Who needs a fire extinguisher, when you have MY lungs?!" - Integza

Interesting idea, I think you should build the fuel and the rocket separate, I think you're just burning your nozzle off super fast. So you should print a nozzle and case out of something that won't burn as much (perhaps ceramic) and the fuel should be an insert into said nozzle and body

Nice! Looking forward to the follow up

Okay, just found you and you sir have won me over! Subbed!

I'm very much like to see Integza hit 1 million subs. His contents are very good. Good Luck !!!. Love from Sri Lanka

Ayyy you actually wore your safety goggles the whole time! Now you just need to get an emergency cut-off valve for your propellant so you don't end up blowing your attic up.

This guy is the funnest insane person I have yet to find on RU-vid. I hope he does not blow himself up. The content is too good.

Brilliant, I love outside of the box thinking

I don't watch your stuff every day, or even every week. About once a month though I fall down a youtube Integza hole and watch 20 of your videos back to back. Today, is that day.

Please do these kinds of tests outside, the fumes less than optimal. Stay safe ;)

That's the best video I saw ever.... Parabens

Of all the places to do this. An attic full of insulation is by far the best

Print a ceramic test chamber with ceramic nozzle that holds the 3D printed fuel. Just print fuel cells and insert them in the ceramic engine for a reusable engine that won’t melt 😁

You could explore creating your own filliment with more... Desirable properties. Alternative suggestion, design a 3D printed rocket (including nozzle) that accepts sugar rockets as a sort of fuel cartridge. You could even rig up a way to pump oxygen through a sugar rocket!

You are a genius and I love you !

Hi, novice engineering student here and id like to recommend you try an elongated thrust nozzel made of ceramic or brass. The elongated geometry of the nozzel would provide more thrust by causing rapid acceleration of the gas/flame coming from the combustion chamber. Also print a hard outer shell of 100% fill and a burn core of abs at 75-90% in fill to achieve better surface area and more aggressive combustion

" Polylactic Acid (PLA) is different than most thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane" SUGAR CANE

As far as I'm aware, the sparkly thing is straight up just called a sparkler.

thanks 4 your passion mr.

3:04 that one anoying kid when you kill them in any game that has voice chat

Funny you upload this nearly on my birthday and sing happy birthday xD Is quite a strange but wonderful coincidence that one of my favorite RU-vidrs would upload this

you should be amazed at the creativity of the english language to know that it has named those sparkly things sparklers.

you are insane! thanks for the video!!!!

This was one of the best episides yet

i say that we are on the right path to build the first solid wood rocket engine in the history XD

I have this scary feeling that one day Integza will blow the roof off of his house.

One that actually works and can proceed with testing. Well done So it turned out you were doing the right thing all along. What seemed like failure was actually successful

This was randomly suggested by youtube. I am not disappointed this was both very cool and hilarious

In your next video make a car that's powered by a rocket engine. Is it just me that would like to see a miniature car with a rocket engine? 🤯🤯

Those names sound like candy crush combos! Can u guys imagine the smell of candy over there?! Such a cool vid!

You are now my favorite RU-vidr

12:37 "WHO NEEDS A FIRE EXTINGUISHER WHEN YOU HAVE MY LUNGS"

A cool idea to try would be to print a solid propellent grain in one go by adding an oxidiser in the resin (KNO3), the resin itself is fine enough reductor so you do not need to add sugar. This could give you a lot of control over grain geometry, and you could make it fit in any shape pressure vessel. I would recommend a pretty thick piece of PVC tubing or a little thinner aluminium/steel tubing, put a thin insulator between the grain and the tubing to prevent burning your PVC to much or melting your aluminium.

There is a Magnetic filament you could use to 3D print Bullets or little Rockets and fire them in your Railgun. You know.. the Railgun you should be working on!

To get the fuel to burn more entirely you need a metal casing. In highschool I was in a rocket club that got funding and advice from NASA. We had commercialy produced hybrid engines that had a metel casing and acrylic fuel. Plastic is actually pretty energy dense.

3:29, Integza just created a Paradox. Godamn.

The moment when they said it smeels like caramel and inetzga just looks at the rocket like he wanna lick it so bad....

The candle topper things look a bit like what people here in Iowa call "Sparklers", a type of firework that consists of a a long, thin metal rod, with about half the rod coated in a layer of a grey, flammable substance. When lit, the grey substance gives off a bright light, and gives off sparks as it slowly burns along the length of the rod... In case it wasn't obvious to anyone reading this, you're supposed to hold the end of the rod that doesn't have any flammable stuff on it.

What a cool experiment!

first time on the channel love it mate!

You should collab with the plasma channel try to make a glider powered by ionic wind and you should also try using other solid fuels like black powder mixed with oxygen in a stronger rocket chamber, like a steel pipe.

I think you should build a rocket powered plane

Bom trabalho com estes vídeos, realmente é um canal com qualidade continua com o bom trabalho!

Nice video, you have a new subscriber! Saludos desde España!

What of you bought yourself one of those 3D Printer „waste Recyclers“ where you Melt down the plastic again, and With this you could enrich the abs plastic With Sugar!

Whoa the aerospike nozzle engine has VTEC. Very cool when VTEC hits

To increase the efficiency, i would model a thin tube of material through the fuel body to channel the oxidizer towards the end at first, and slowly shifting backwards as the tube burns

Super video! I applauded for $2.00 👏

love your videos integza

Very interesting concept

3D print your parts to make a mold for metal casting, dont waste those rockets! love watching your videos

I thought burning ABS produced some toxic fumes... for what I am reading is not THAT bad, but still be careful bro! Nice video as always.

Hey Integza. The sparkly things you put on birthday cakes are called "sparklers" in English. Also I've never seen them put on birthday cakes anywhere but in Portugal. But I digress. Rocket on!

This is pretty interesting, you got yourself a new subscriber

Thanks for getting recommend to me

Use 10% filling on the chambers and parts of the engine that are hollow (maybe modifying the filling pattern to help with the flow) to give the engine more fuel to burn on. And making a metal or clay sheath where you can put the engines in, since you're using the same outside format for most of them, you could ideally use the same sheath for all the tests.

You could try fitting the fuel into a ceramic shell that lets the fuel burn completely maybe you could try and make nosles that can be screwed onto the creamic body or otherwise be attached and only make the fuel out of abs(you could also try pla)

Love your videos, very funny and enjoyable. I would like to see you use some safety precautions though. Especially since you are burning some resin, it may be a good idea to wear a respirator. Keep the good work going.

these videos are great!

I think it is about time you start casting some of the parts

I think a smaller project like a Emergency stop for the oxygen would be potentially handy 😅 Awesome stuff!

In English, the sparkling things are just called sparklers, but your analogy about them works too
