I tested ALL the ROCKET PROPELLANTS I could find online

[@glitchygarden6973]

Some things I want to point out: - You need certain types of charcoal for "usable" black powder. Namely willow, balsa etc. - You need to ball mill the potassium nitrate for nearly all KNO3 based propellants. Please invest in one, as it's also safer. - Be careful when you compact your black powder rocket motors. Any cracks developed during manufacture/burning would lead to an explosion. I like using a press better than a mallet. - The thing used for the match heads is not red phosphorus. It's a mix of chlorate/perchlorate oxidizer, some sort of fuel, glue and stuff. The phosphorus is actually in the striker paper. Phosphorus is some nasty stuff, please do not experiment with them. - Rocket candy is famous because both the oxidizer and the fuel can be dissolved in water, thus eliminating any grinding in the manufacturing process. It seems like you didn't actually make the "candy" and just used the powder mixture, which would require some good grinding, probably with a ball mill. - Acetone would not ruin nitrocellulose, but the amount of solvent in the mixture can determine the burn ratio. IIRC, the solvent content is precisely controlled to modify the burn rate of the powder in firearm ammunition. - Perchlorates are really powerful oxidizers, I would recommend you start with KNO3 first. Store them safely, until you have access to a better lab/testing site. Be careful and have fun.

Our base is Ammonium perchlorate, a few different sized grains of aluminum powder, copper, and a small list of other ingredients to help the casting process. Turns out making a solid rocket motor is a lot more like cooking, everyone has their preferred ingredients as MIT has a similar formula they named "Cherry limeade", look it up it's pretty cool.

Integza, when I have made KNO3+sucrose rocket-candy, I have used a 2:1 weight ratio dissolved in water with a small amount of karo syrup and ferrous oxide powder, gradually heated and continuously stirred until it was dehydrated into a very thick paste. this super-saturated solution under low heat co-crystalizes the components. the paste while hot is to be handled much like taffy, pressed into the mold used to shape the fuel grain. done correctly, while it is hot to prevent inclusion of voids, this produces a solid grain and creates a very uniform burn when ignited. if you do this, use a water-buffered double-boiler for *SAFETY* as this will prevent the paste from heating to its auto-ignition temperature. and don't do it inside your home, even with a double-boiler... just... trust me on this.

If you need help with soldering, I've been soldering for most of my life and can give you some advice. First of all your set-up and equipment makes a big difference, especially for tiny SMD level stuff. You can certainly use those direct plug in hobbyists irons but they're best for big stuff or large through hole soldering. What you want is a soldering station that can regulate it's temperature and you can control that temperature with a dial or buttons. The reason temperature is important is because when too cold the solder won't melt completely to wet the two surfaces and you'll get a cold joint, too hot and all the flux will burn off really fast and the solder will start acting weird, wanting to go everywhere and get stringy and follow the iron tip. When your temperature and flux is just right the solder acts like a water droplet on a hydrophobic surface, it has a lot of surface tension and only wants to spread out on metal. But again using a hot direct plug in hobbyists iron all the flux burns off too fast before the solder can both spread out in the joint, and consolidate itself into the least surface area through surface tension when you remove the iron. For the iron itself you want one that you can change the tips because using the proper tip is also important, too small and you won't get enough heat into the joint and too big you'll be hitting everything around the joint. Another added benefit of these stations is that you can change the heating element or tip as they wear out also if the temperature can be set low enough you can use these stations for plastic welding, you set the temp to just above the glass transition temperature of the plastic you're working with and have a dedicated tip just for plastic welding. If you get into more advanced stuff it also helps A LOT to preheat the board on a hotplate or in an oven before soldering, not hot enough to melt the solder on the board but hot enough so that touching the iron to a joint is enough to bump the joint up to a liquid state and the rest of the board around the joint isn't pulling heat away because it's already warm. Now for the soldering. You don't have to add any flux if your set-up is correct because there should be flux in the center of the solder wire. But for learning and delicate stuff adding flux during soldering and cleaning it off with isopropyl after wont hurt anything. You want your iron tip to be shiny and clean, that's a big factor in using too much heat because a dirty tip is insulated from the joint and so you turn the temperature of the iron up to get the heat through that layer. While the iron is heating up you want to hold the solder wire to the tip so it immediately gets tinned, or wet with solder. When up to temp the iron is too hot if you get a big puff of smoke whenever you touch the solder wire too the iron, that's all the flux burning off you want a slow steady stream of smoke coming from the tip. Now you want a wet sponge or copper brillo pad to wipe the tip on to remove excess solder and keep the tip clean. When you go in to solder something I like to have a tiny bit of solder on the tip to help with heat transfer into the joint but it's not necessary. The important part is that you heat up the joint first with the iron tip then add the solder wire directly to the joint. What happens is the flux in the solder wire melts first and coats the joint, if you hit the iron tip first the flux can get burnt off by the tip before any gets into the joint. Next the solder itself turns to a liquid and follows the flux into the joint. Because the flux is there the solder wants to wet the metal and spread into the joint through capillary action and surface tension. Then you want to remove the iron before all the flux is burnt off so that the liquid solder can consolidate to the minimum surface area through surface tension.

For a future video you could toy around with rocket nozzle designs? Different bulby shapes, simple cones, and length makes a big difference too

[@videtior]

Bro make An relanding rocket🚀🚀

[@sahilpaple8781]

Yaa please..

[@sanathanihindu]

Yesss...

[@videtior]

Yep

[@gianlucadionisi6730]

Future Video Idea: You definitely should try making flash powder, maybe the one with aluminum and potassium nitrate, taking the precautions. With that, you could make rocket propellant, or even a mortar, to change a bit. It is a good experience and very fun process. PD: Integza you are unique, continue doing this type of content, we love it!

[@vitolapjagruesacomo]

Nice idea, that mixture is safer than candy, and does not need cooking. It would be excellent if he sees it and could try it.

[@gianpxx]

Hey, that's cool, flash powder is more efficient than other fuels, Cheers from Brazil

[@maitenadionisi2509]

Thats a good propellant and easier to make. It will open him new doors to continue without much complication.

[@ayoshakozlov]

WOWWW Im so excited to se that video if integza reads it. 🚀🚀🚀

[@almerindaromeira8352]

For me the most incredible thing is that this is all happening in Portugal and no one has knocked at his door.

[@panagiotiskatev1101]

Make a ramjet engine in a future video

[@a_tsalmpo]

Yes!! Do exactly that!

[@Ragnarok99915]

Αδερφε δεν έχω κερδίσει ούτε καρβέλι ψωμί σε λαχνό από Πανηγύρι …κάνε κάτι να πάρουμε τον εκτυπωτή

[@dangus5326]

good video. I like

[@alexandersmolski7379]

video idea: you should try and build an RC car(or plane) then use the final rocket from today's video to create some sort of speed boost. another idea could be to try and build a rocket-powered tesla turbine?

[@resurgam_b7]

Video idea: A rocket powered whistle, see if you can make the "nozzle" into a whistle and then see how loud you can get it and how it compares to traditional lung powered whistles.

[@Tamada357]

well lol

[@XXXXPyrofreakXXXX]

To make the rocket powered whistle even louder he could use whistle mix as rocket fuel, it is made from sodium benzoate and potassium perchlorate. but be careful,it explodes if you hit it with a hammer!

[@resurgam_b7]

@@XXXXPyrofreakXXXX Sounds like it would be right up his alley 🤣

[@joakimvhes302]

Video idea: How about you try to build a water turbine and use it for a power generator? You could test various different turbines, and see if there are alternate solutions to what is already being used around the world. Small advice for 11:04 For bits that are problematic to grind into fine powder a good ol' mortar would be helpful. There are nice ceramic ones that chemists use, or you could try and 3D print one in resin for yourself (you can even print a ceramic one now that I thought of it). Mortar is also a good tool in terms of how easy it can be to control the level of how fine you grind something. Takes some labor, but for the kind of the tests you do, and amounts you use, it shouldn't really be that much of a problem. Also allow me to add something more; some propellants/explosives work better when they are a bit thicker, instead of a fine powder (example: look at the powder you sourced from the shotgun shells).

[@theaspiringone2571]

Future video idea: Using a gas vapor to power different types of engine???

[@ujjc001]

Future Video Idea: Can you 3D print your rocket fuels, and, instead of just one hole up the middle, try various designs like a honeycomb, twists, etc, to see if more or different air to fuel interfaces change how well they combust. Also, would be interesting to see if you can make a fuel medium that can be 3D printed at all!

[@schwuzi]

It could work with an inkjet 3D printer. It applies a kind of glue between every layer and then prints on the fuel.

[@jimurrata6785]

Characterization of fuel grain geometry is pretty well known. (center, concentric, star, D-grain, end and moon burner, etc...) Printing a hybrid fuel grain is definitely possible. You would need to have near 100% infill or the increase in surface area would lead to catastrophic over pressure.

[@TravisLee33]

I'd love to see a video on how a van der graaff machine works and its practical uses In the past as well as what it's used for in modern times.

[@mrspoon6321]

Future video mabey: a fully 3d printable rocket with compressing apparatus to make fuel that can simply be put into the rocket somehow

[@openhostwebservices6086]

Now that you have a propellant now let’s launch something but I’ve always been interested in the centrifugal space launcher method. I think that would be really cool to see and understand how it works.

[@Thasrissian]

As far as soldering goes it might be worth testing different types to see which works best for you. Solders without lead in them can behave differently from ones with it in the solder composition. It might also be worth investing in a soldering station with a temperature control.

[@arnemaschmann7629]

As a future theme for a video i would like to see a tug of war between to minicars propelled by rockets. It would compare initial energy vs longer burns

[@theviperiscalling]

As a followup to your combustion engines, you should make a turbocharger! Uses the exhaust gas to compress the air, improving the fuel-air mix. It'd be a difficult project but very cool to see in-action, especially transparent resin!

[@sigmamale4147]

Or a more simple supercharger, that would be cool too

[@RRVCrinale]

For a minute I thought you wanted him to power one with a rocket like the old Turboniques.

[@theviperiscalling]

@@RRVCrinale that'd be sick too! Either way, temps, tolerance and pressures would be difficult at a meaningful rpm, but as a demo piece, or for lost-plastic casting?

[@Givesamanhope]

hes teaching us how to make explosives next time make a guided rocket (safely) like bps space i allways wanted to see a javalin like petershripol

[@Diesr]

yeah thats a great idea lmao

[@dosmanx2781]

i want files

[@dosmanx2781]

for my 3d channel

[@mattfreeman2465]

Video idea….. make a jet engine utilising a toroidal fan at the front to focus the air flow into the compressor. You could also replace the turbine with a spiral tan, such as the nozzle you made for the CO2 rocket, thus focusing the thrust.

[@kwadaholicreviews6354]

I'd love to see you do one of those compressed air and water rockets like a professional type they go ridiculously high

[@themrflibbl]

I made one using a water cooler bottle and it went way to far, several gardens over, luckily it came flying back over my wall when the neighbour brought it back. Those things hurt if they hit you even when empty.

[@gbhadoria6439]

How about 3d print a 3d printer using your 3d printer. Then you can say you 3d printed 3d printer from which you 3d printed you 3d nozzel.

[@lets_play4288]

Make a supersonic wind tunnel and test a hybrid ramjet… It’s when solid propellant is used for a ramjet. ASA maybe?

[@brembobremse3690]

Idea for video: Make 3d printed Newcomen non rotative atmospheric steam engine. Show how Industrial Revolution get started and change this world forever!!!

[@antonioamarildo8752]

Finally a good suggestion!

[@eugecocornetti8697]

video idea: Can you make a rocket with the last propellant? It would be very cool. If a rocket with potassium nitrate can fly up to 500 meter high I can't even imagine how high can go one with the Ammonium Perchlorate!

[@markinipannini]

As he said it's what nasa uses, so i'm thinking at least 503 meters...

[@eugecocornetti8697]

at least 4 times

[@eugecocornetti8697]

It would be awsome bu also dangerous

[@falsofalsari]

if in open air it should be safe

[@shun-patrickcharbonneau5530]

i would love to see you make an underwater rocket ( that s probably called a torpedo ) and luch it , would be cool if you could make it go crazy fast and see the slomo of that

[@MinePossu]

Send a tomato to space.

[@jakobfindlay4136]

The kind of flux you get matters, I was using plumbers flux and got disgusting looking solder joints changed to mg chemical flux and got amazing looking joints with everything else being the same.SDG electronics did a great video comparing a bunch of different flux's and is worth checking out

[@Mr.deadly681]

thanks integza for you give to another person the printer

[@Maxl51]

Since you probably have made a lot of prints that failed or you don’t need anymore. It would be a perfect Idee to try to „recycle“ them. There’s also a Tutorial on Thingiverse, it is called „Petamentor“. You can improve that design and show us what we can do! BTW i Love your Videos ❤️

[@anishlaha4020]

Here's a theme for a future video: How to turn a rocket into a weapon of destruction, A step by step on what NOT to do with a rocket to make it into a weapon of destruction! And use a bulletproof polycarbonate enclosure so you can test this invention without killing yourself or destroying your house!

[@charlienicholsonr]

Future video idea: Build a rocket that takes tomatoes to space where they will never be seen again by humans.

[@MoonaKissa]

You should make a liquid nitrogen + boiling water propelled rocket engine or kind of reaction control system / RCS kind of like in this video! kzbin.info/www/bejne/Z5KUmnuLmcRkarM

[@kitsune3769]

I would be curious to see what happens when you mix all of them into one
