One of the most enjoyable aspects is the absolute minimum amount of fluff, but an abundance of information using the correct terminology, and almost no fear in presenting the viewer with a complete picture. You're not hiding information away because it might be dangerous, that is tragically rare these days. Be concise, use the right words, tell the whole story. Been around since the photolexicon days, glad to see you've continued to follow your passions.

This channel always reminds me of doing something stupid/dangerous with a friend and getting caught by their dad, but instead of getting in trouble he just sternly teaches you literally everything about how to do what you were doing. So much great info, keep it up!

If you were a science teacher at some stage in life, or every became one, I'll bet the lowest mark in your classes was 90% and every single kid loved you and as an adult looked back on you as the biggest influence on their life and were immensely appreciative of what you did for them. In a world gone more mad than ever before, I'm sure all your adult viewers think they are so much better off for having found your channel and are similarly appreciative for the escape you bring them. Thank you for your significant efforts in doing these Vids.

"Today on Cooking with Tech Ingredients!"

2:25 Tech Ingredients is going to teach us how to built our own VA-111 Shkval supercavitating torpedo because, you know, what else are you doing next sunday? Coming soon!

RATO: Rocket Assist Towing Option.

Wow…from Railguns to Rockets. Not only the finished product, but a complete guide on how it is done. Safety first and why you don’t do bone head things. Let the experts do it, but come along for the ride. It is truly a start to finish journey. Well done. Great video production as well!!

Iron oxide, or other iron containing compounds like ferrocene, can accelerate the burn rate far in excess of any reduction in particle size of the ammonium perchlorate. The reason is that the rate limiting step is the decomposition of AP to perchloric acid, and this is ultimately limited by the fact that the AP forms a liquid layer on the burning surface, so smaller and smaller particles of AP don't help you past a point. This is why ferrocene can be much more effective than Fe2O3, as the iron it contains can mix in with the molten AP at a molecular level, rather than the molten AP being broken down over the surface of iron oxide particles (and iron containing plasma...)

Those are some NICE motors. Great job.

You guys are living my dream doing science while getting others hooked on it. Love your content.

I love these videos. From the exceptional professionalism, to the amount of complete, precise information, to the father-son collaboration. The latter being, perhaps, the most inspiring, as well as aspiring factor. There are very few KZfaq channels (if any other) with such characteristics. That is, primarily, what makes this channel so exceptional. Thank you, for another wonderful video. Best regards from Europe.

"I don't know if I want to mix up 10kgs of rocket fuel in the lab. It's just, .... you know....."

I have no intention of ever making a rocket engine and yet I've watched every video intensly, just in case ... :)

Cutting of cardboard tubes: my method is easy and very effective - I use a small pipe cutter with a very sharp cutter wheel and a wooden dowel which fits closely in the cardboard tube to prevent it from being crushed. Works perfectly, quickly and is very safe.

Cannot explain how thankful i am for content like this. The freedom with which you give away hard earned knowledge is inspiring. I wish there were more channels and people like this. I am confident that your audience will grow as more people discover your content.

My admiration is on so many levels for these videos. The thought about what other people would go through and the helpful advice. Just....awesome.

Off topic but I just recently built myself some of those flat panel speakers and I must say they sound amazing. Love your work! -Texas🤘🏼🤘🏼

So James Bond had Q making all his cool gadgets, and Batman had Lucius Fox... What super hero has you out on loan?

The look on your face when that motor fires and the trailer starts moving is fantastic. It really is the little boy in us even at our now more advanced age that drives us to do this stuff. Well done.

Thank you for the amazing content. I love all that you do. From speakers to rockets to air conditioned computer cooling. I really appreciate the details too, even if I don't understand it all right away, it makes it much more accessible to look things up.

"imagine to be a youtuber and doing this stuff" well, id say it is "imagine doing whatever is fun for you and making a living on it on youtube"

Ah, a long awaited video. A month feels like an eternity. Worth it every time, and an hour long too. Can’t wait to watch this!

Best show on the net, keep up the great work, because I/we love it!

Well worth the watch. There simply is not a better channel on KZfaq.

How is this channel not over 1M subs!? 👍👍👍

loved the response, "Holy Sh!t, Oh my God!" then on replace you can see mach diamonds @ 57:17 ...Nice.

No exaggeration, favorite youtube channel. The fact that content like this is free blows my mind. Also really REALLY appreciate the notes about safety and proper disposal of all materials involved. Too many people gloss over those details and it can be catastrophic, even with something as benign appearing as epoxy.

The passion of the teacher & eloquence of delivery are why I am definitely subscribed. Keep up the good work.

"...and if you are stupid..." :D well said when explaining about disposing of potentially dangerous epoxy and other waste. Some lessons just don't sink in, if toned down too much. Unexpectedly made my day :)

@2:23 You'll probably never hear a man say that he's working on a rocket powered torpedo more casually.

man, my dad would have loved this channel, he dabbled in so many of the topics you present. kudos.

Simply one of the best science channels on KZfaq!

I found when making BATES grains for rocket motors, using a wooden dowel coated in lithium grease worked very well to keep the core surface smooth. You just have to let the propellant cool a little bit before removing the dowel. Having a core guide is also immensely helpful!

That "Circle back" bit gave me a good laugh. I'm glad you don't use it like she does though, since I do eventually want to hear about the composites.

Seriously love the level of detail put on to these videos... you would think an hour would be long and boring but I was stuck to the screen the whole time! Never even bothered looking at my phone. Keep up the good work!

This is the best most useful and informative channel that exists in the whole platform

You're the instructor I wish I had for every class I've taken. I love learning while watching you have fun!

Love ‘em!! I saw how long the video was and couldn’t have been happier. Over an hour with you all is a privilege and a pleasure. Thanks for all the hard work you put in.

I can always count on Tech Ingredients for the highest quality content. Thank you for what you do.

I sure could have used you a couple years ago. I was helping my son with a science experiment. We were making rocket engines with household products. I tried adding a little charcoal, thought it would do some good. Luckily we practiced safety. We setup all the lab equipment and the cameras. We had a remote to ignite the rocket. We were behind an earthen hill. When ignited, after about 1/2 second it exploded. Neighbor came running out, the neighborhood started sending emails. I told the neighbor we were trying to make a rocket motor and the nozzle was too small. Wife actually came out and threatened to call the police on me. It was heard a mile away. I took the film, and looked at each frame, and calculated the parts were flying away over 100 MPH. A lot over. It was plastic, and we were shielded by trees. YES , BE SAFE. Not only from the experiment, but from spouse too. It was fun until then. I sure could have used your help.

This man just said they're working on torpedoes?? lmao this is why I love this channel

Gives you an appreciation for how much fuel must be packed into the Shuttle's solid rocket boosters. Insane!

Best science channel I have ever seen.... and I watch a LOT of science channels! I learn more from your random side comments and explanations than I do from most 15 minute videos here on YT! Please never stop doing this! :-)

I would love to see you see up and keep a marine aquarium with high end corals. With your enthusiasm for knowledge and chemistry, and conveying those through youtube I think it would make an amazing long term series.

"you can start your BBQ with these, the smell of chorine goes quite quickly"... LOL, spat coffee all over my keyboard.

I just love this shit. I would love to feel the energy standing next to it.

Really enjoy and appreciate your hard work, clarity and quality of the videos you've created here on KZfaq. Thanks

The exclamations of joyful amazement at what the host has wrought are infectious. Excellent work.

Heyy it’s been almost 6 weeks, I got worried when I didn’t see a post for a while. Great video ! Thank you for the best explanations.

Great work as always. I feel like the editing and camerawork have gotten even better, very impressive.

Really appreciate the extra info cards. I know looking it up on the internet is easy but often we plan it for later and never do.

I just wanted to say that you are dad goals and I love your channel. Thanks for all you do

man i love this content , for some one that cannot get ahold of this stuff in my country , im looking forward to the hybrid rockets , and maybe in the future watch you guys build a liquid , keep up the great content

On the outro there... seeing the same nitrous solenoids i run on my car plumbed into a rocket engine... hell ya. Nitrous oxide rockets. Thats awesome.

When I saw that the length of the video was over 1 hour, I thought I'd write to say that it's too long, and that people won't watch it. By the time I'm writing this, I've finished watching it.... Fascinating stuff!! Great work! Love this channel!

I remember 'grasping' differential pressure propulsion and lift. It was on a late watch admiring the first F-4 Phantom I had ever seen up close (yes, "admiring", it was a record shattering legend in front of me which was being phased out.). The chief in charge came up and asked if I knew how it 'flew'. One of the most memorable conversations of my life ensued... I knew the theories, but to have someone "walk" me through the physics with a real life example actually transformed my conceptions. Please keep up the good work. Enjoying your content, TI

This might come off as a little shameless, but can we have an update on these projects: HHO Shaped Charge(I know you still might me making the trench) Different types of composites 13000 watt generator Composite body armour The drone Hydrogen Pulse Detonation Engine Explosive wire

Scrape the sides of the cup!! That drove me crazy.

I really love this channel, 55mins before they get to "using our rockets" from the title ... the rest of youtube is clickbait and these guys drop an hour of knowledge no problem

Oh what fun! Sparks in the night, rocket's bright! Love it!

These vids remind me of an amped up modern version of Mr. Wizard.

Try using a plastic straw with a sealed end. In theory you wouldn’t have to remove it, your igniter would just need to be strong enough to melt through It and light the propellant. Then the straw just burns away

😲😲!! HOLY S*#T is a understatement! I mean the rocket grains speak for themselves. The recipe for the whole project is top notch. PLUS in the format of a damn near full feature professional film! Never enough of what your crew produce outta that lab.

Amazing work. Love the step-by-step walkthroughs!

Me: My Trailer is stuck, how will I get it free? Smarter Every Day: Snatchblock! Tech Ingredients: Rockets!

Seems like you could fabricate the core tube cutting jig to also be a drill guide. 2 in 1 tool for the home gamer.

Love the new funny arrows post edit. Informative, fun video, worth the wait.

I used to work at ATK that at the time owned the rocket motor company that makes the SRBs and I've spoken to them about this subject at trade shows where my division was at with them. Fascinating stuff. Excellent video.

Such a great video! So much good info and good edits. Honestly the only thing missing is some B roll footage or some close up stills of the construction process, but that is more of a nit pick. I really want my niece to watch these vids and dream of being a rocket scientist or engineer.

This feels like the TV show "Mythbusters" went to college, and I love it. Keep it up!

loved every second of the video, cried of joy with the peter schilling major tom alussion.

That demo was great! It gave a good “scale” of the rocket motor impulse. Thanks!

I clicked like twice, only to notice that it unlikes the video when doing that. So i clicked three times :)

Would have liked to see all the thrust profiles on one graph at the end, or side by side. Also, any significant difference in final weight of the difference mixes?

You were as delighted with the result as we were! Love it.

"The only thing that generates more heat in combustion that aluminium is boron" to paraphrase. You speak these words and I immediately get flashbacks to 'Ignition!' by John D Clark.

There goes my productivity this morning!

I like the idea of the hybrid motor. I've seen the ones running nitrous oxide with a solid fuel. Other than solid fuel there is really no other choice for hobbyists. Cryo it way too complicated. Thanks for the entertaining videos..

I have never wanted to hang out with someone as much as you. Love this stuff! Thank you

As a kid, my father and I loved model rockets. Now in my early 60’s this really makes me smile. Thanks

Total impulse should be measured in N*s. You are integrating over the time here right? Also makes sense since N*s = kg * m/s in Si units. This is mass times velocity which is an impulse!

How does youtube decide which videos to close caption, I can not think of a better channel to have that service available

i cant believe ive watched for a whole hour. i was planning on fast forwarding, but this is so densely packed with interesting info... well done!

Fantastic motors! Really beautiful burns. As usual, your in depth explanations and attention to detail and precision ("neatness counts") make your videos must see viewing for anyone with a love of applied science. Can’t wait for your next one.

Always enjoy your videos but dang there sure a lot of ad breaks these days.

This question is part humor, part morbid curiosity, and partly legal...how many of those things can you fire off at the same time before people in suits show up? I know in previous video's you mentioned the maximum size a single hobby rocket a person can use in the US was, but could you say set off 10 at once, 100 at once legally? Because if so, I'd like to see that trailer fly :P (assuming it's even possible to do it safely lol)

Excited for the next video!

I have a suggestion for a possible future experiment: When making carbon fiber, kevlar, fiberglass or some other composite material... What would happen if you tried to turn the binding epoxy into aerogel? [EDIT: Nevermind, just saw your response to this question when I asked two weeks ago. But keep reading!] On a related note, here is something else that I would love to see you explore some day. *(Wall of text warning.)* Different allotropes of carbon can be merged, enabling you to combine useful their properties into a single material. Here are some of my favorite examples: - Carbon Nanobuds: These are literally carbon nanotubes with fullerenes stuck to them, giving you some of the amazing physical properties of both parent allotropes. - Graphenated Carbon Nanotubes: These are carbon nanotubes fused with sheets of graphene, which not only enables you to get the useful electrical properties of both materials (great for making battey-capacitor hybrids), but may also potentially allow you to have a 3D block of graphene without it just turning into graphite, as the sheets are effectively held together with 'ropes' instead of being allowed to slide past eachother. - Graphene Carbon Fiber: Not really an allotrope per se, but the addition of graphene to the PAN when producing carbon fiber makes for a stronger and stiffer end result, while also requiring less energy. - Aerographene: Again, not necessarily an allotrope, but it is possible to turn graphene into an aerogel. The end result is a material that is up to 7 times lighter than air (though it doesn't float because of its porousity), and is a good thermal insulator while still being an excellent electrical conductor. It's still aerogel however, and as such it can be rather delicate. I wonder if you could combine aerographene, graphenated carbon nanotubes, carbon buds and carbon fiber into a single material that is both lighter and stronger than traditional carbon fiber. In order to truly do such a material justice, however, you will also need the right kind of binder. I get the feeling that the stuff that is most often used in carbon fiber is just too mundane and general purpose, and would probably hold this hypothetical material back from reaching its true potential. Then again, I don't have any experience, just fast access to knowledge. So I very well could be talking completely out of my ass.

The unit for impulse is N·s (says "total impulse = __ N" a lot, ahhaha)

Does the water of crystallization (in sugar or Sorbitol) play any part in further reducing the thermodynamic efficiency of the sugar-based rocket?

One of my favorite videos you've ever done!

Great job! Very nice. Loved seeing the after dark test firings. There's a lot if energy in that simple mixture!

Just curious, what do your neighbors think of Starbase North?

You probably make the dankest scrambled eggs

Fantastic job of both teaching and entertaining simultaneously!

I need to thank you. I'm a retired and unfortunately disabled 52-year-old who discovered your channel last year. With only basic high school and college chemistry, you generated more interest than anybody else ever did. I've been trying to learn basic chemistry all over again and have progressed a bit and collected quite a bit of lab equipment and I think I should be a Skylighter poster boy. The more I learn, the more I need to learn. In this same way, I became a senior software developer, beginning 20 years ago. I have that same drive and excitement for learning the science behind the pretty fireballs. Luckily, my wife understands and my children have that same incredible passion when they take an interest; They have 100% focus and its impossible to tear them away from it or even get their attention. Mama didn't understand it for a long time, butI sure did and now we encourage it wholeheartedly. You put me on this new path, so thank you!

if it has its own engine, it is no longer a trailer, or is it?

Don't mind me while I go grab some popcorn and drink.

Bloody awesome guys! Love it!!!!

Loved this episode. I used to build rockets in my teens. I was always afraid of heating the mix to melt it, so I just mixed the chemicals in water, soaked paper towels, wrapped them around a removable core, and dried them in the sun. I used sugar and potassium perchlorate IIRC. Worked pretty well, but it was very hygroscopic. BTW, one useful tip when using hot melt glue. Just put a little ethanol under the joint, and it will release right away. The surface tension of ethanol is very low and it just gets under the seal causing it to come apart.
