Drones, crowd suppression devices, explosives, rockets. This guy is planning something big.
I think he's personally planning on watering the tree, if you catch my drift. XD
@Quippers United he's a libertarian, I haven't gotten a direct answer but he hearted a comment that i wrote saying I think he's a libertarian.
So he's just putting information out that we all deserve and where that goes it goes.
@SKM 94 I'm not surprised. Anyone who makes his own air conditioner doesn't need, or want, help from anybody.
Don't forget the -getaway boat- yacht.
@Downstream01 If you are going to launch a doomsday device it needs to be from international waters.
52:45 I thought the Challenger disaster was due to a failed internal seal in the SRB. Could max-q affect that at all?
It was. It may be that the extra stress at throttle up was the last straw and the SRB gave way, but it was not the throttled engines themselves that blew.
I was not expecting you to be intrested in rocket science, not gonna lie
Wind shear aloft was also a factor. An in situ plug of debris from exhaust particles and burnt seal material formed in the joint after ignition, which kept the joint from cracking wide open right away. Otherwise Challenger and her crew would have been destroyed right on the pad. When Challenger entered that unusually strong wind shear level (coincidentally near max-q), the flexing of the booster jarred the plug loose. Engine throttle up was the icing on the cake. Once that happened the exhaust gases were essentially a thermite blowtorch flame in a supersonic slipstream; it cut the aft booster attach point, and the aft dome of the external tank, causing liquid hydrogen to stream out. It wasn't long before the bottom of the tank opened up circumferentially like a zipper, and that was all she wrote. Aero forces then broke the whole stack up. All because of something as simple as rubber seals failing in cold temperatures. I hope that answers your question!
@Tech Ingredients saw a video on this. The seal is to keep pressure inside. The way the srbs are made came into play. They were made in sections and joined at the ends using a y shaped edge with an o ring inside to keep pressure on the bottom of the next section, along with some pins. When you watch a video of the challenger taking off you can see some wiggling at the bottom of the srbs. That combined with a cold o ring and the design allowed pressure to leak out. Specifically when it flexed, the o rings should've expanded to keep pressure on the two sections of the srb but didn't and a side of the y connector flexed to let pressure out. Which just happened to be hot and just tore the thing apart. Scott manley has a great video on it. Forgot the name though sorry about that.
@Ethan Smith There wast least one other booster which had one of the pair of O rings fail. The outer of the two O rings was all that stopped it from failing in the same way as Challenger. Like many disasters, it was not caused by just one failed component; it happened because of a concatenation of several circumstances, including cold weather, two failed O rings, failure at exactly the right point for hot gas to be ejected onto the fuel tank, wind shear at Max Q and sloppy manufacturing and safety testing techniques, compounded by managers not listening to the dire warnings which were given by engineers.
In some ways, you can say that they were tragically unlucky on that occasion, but that doesn't give the whole picture. The Columbia disaster was another example of circumstances coming together to create a tragedy. All previous successful flights had had debris falling off the craft at launch, but the crews of those missions were lucky, because it had always failed to dislodge the vital heat shield tiles which completed the events and omissions which led up to the disaster.
Wow, this video was outstanding! Thank you so much for teaching us in such a great way. I love your meticulous explanations, your care in showing us every detail of the process, and your eloquency. Greetings from Germany :)
This was phenomenal. The camera zoom and focus were great. This was an extremely professional video and incredibly informative!
When we were growing up, imagine if we had access to teachers like him. How many more of us would have ended up as scientists.
I did. Obviously he couldn't get into anything this dangerous, but he was extremely hands on and already pushed the boundaries of what the school would tolerate a bit. Honestly they probably would've nixed him if they thought they could find a competent replacement, but that area was notoriously stupid.
Yeah the people in power who control the educational system don’t want a bunch of smart people haha that’s like there worst nightmare
Dude I’d be able to build a fission reactor out of grass and portal ray gun that’s a wearable like watch for the consumer market by now if he was my science teach .
This was exceptional! Kind of amazed when you picked up the Ammonium Perchlorate, being familiar with that stuff, as I did not realize that it could be obtained outside of the Space Program. We in Henderson, NV. remember that stuff. Last amazing videos of yours I saw were the SPEAKER panel tests. You are an incredible teacher!! Thanks!
Awesome, thank you!
Congratulations for the scientific spirit Sir! And thanks a lot for sharing your experience. Guys like Werner Von Braun, would have been proud of you.
Some of the chemistry involved is very complex, there's a lot of math in the depths, but he makes it for a great way to have people of all ages interested in science and inspired, and I find that is great!
I would have paid to have a teacher like him in high school. An hour long video that seemed like 10 min. Thank you for your hard work!
Indeed same feelings, such easy introduction and very interesting!
hes our new mr wizard loved that show as a child, when i thought as a child, acted a child. since becoming a man ive had to put away childish thing. tech ingredients fills the spot perfectly
At mine, high school, in the 80's & early 90's they taught some of these ways chems can be used. No more, just that America is an evil country & it should be hated. Very anti-commie back then too. Now they're top professors at many universities & even sooner. Not too pleased or optimistic about were we'll end up if this socialism/communism popularity continues and isn't countered with how America is quite awesome . But these schools, constantly teaching our own children to hate America and only look at the bad things that happened. Not gonna be a recipe for survival
I had such a teacher back in HS. I don't remember the reason, but in class he created a little NI₃ to spread out in the hallway. You know, that fun stuff made by soaking iodine crystals with household ammonia! DON'T try this at home if you know nothing about it.
He disappeared from the school's faculty the following year, and a couple of years later I was working as a grocery bagger in the local market while he was a shelf stocker! The owner of the market sat on the school board that probably had something to do with deciding his career change!
Absolutely amazing how he keeps the presentation coherent without pauses or edits
This video was the same density of information as my university lectures have, except the topic is really interesting so watching through a whole hour is done with little effort. Kudos to you and your team!
As a Veteran Air Force Rocket Fuel Handler I found this video really fun to watch. I used to work with UMDH hydrazine and N2O4 nitrogen tetroxide. These were extremely dangerous and poisonous chemicals that we worked with in amounts in the tens of thousands of gallons. I would love to spend a day in this guys garage.
I salute you, Air Force Veteran too. Love to get ahold of some jp4 if I remember right, in Duluth back in 78 - 82.
Wow, I really lucked out today !! This is exactly the video I was hoping to find about rocket engine building. So detailed and clear, you simply cannot do better. More importantly this channel is amazing and your a phenomenal teacher. I subbed up right away as I did not want to chance losing track of it. I can't wait to have an opportunity to see more videos from you. Thank you very much for your time and effort in making great videos to watch and to learn with. Thanks again and Take care
Thank you! I thoroughly enjoyed all experimental sciences ny whole life. But hit a big depression era ss I turned 41. Your videos have been drastically helping reignite my science spark again.
Truly Thank you!
Absolutely love your vids. I will probably never build rocket engines but I sure enjoy watching the process . Very informative , well made super detailed video. Thank you for sharing your passion with the world . Very inspiring stuff !
It's hard not to feel a sense of wonder and passion when it comes to rockets (and other things that go boom)! You did a fantastic job here walking through the process, and even have me feeling the urge to put together a rocket just for some fun! Merry Christmas!
A very well put together video. I build rockets also and never heard of the rocket motor company. I've always used thick walled cardboard and line it with graphite. I'll definitely check that company out.
I remember when I first found your channel, it was at the very beginning and immediately subscribed. I was so afraid you might not get traction and shut it down. I'm so grateful others have found as much value in your channel as I have.
I just found your channel today and can I say, it's refreshing to see a person of science describing these techniques. I found dozens upon dozens of videos I will be watching and liking! Thank you for treating us as intellectual people but still teaching us in full. I feel like I'm back in university!
This was a great video! Really appreciate the work you’re doing!
Thank you for sharing your knowledge with us all. I really appreciate the level of detail you put into explaining everything.
I'm reasonably certain that I could follow your meticulous instruction over a radio...you're BRILLIANT at how you convey your subject matter! Thank you!
I do actually listen to his videos while I'm driving or working.
Awesome communicator. He ought to be a High School science teacher to inspire the next generation of engineers.
I absolutely love this mans channel. I can watch it on fast forward and catch every word because he speaks so eloquently; covering every step and bit of information with such a flow.
@Rich Marceau How about president 8) I'd vote.
Nice 🪐-Saturn-🪐 imagery in your opening sequence logo -Tech Ingredients-. For any curious its the image of the Hard drive inner disc with ring imagery. 💽.
Nice to know. .
I can't believe this video is more than an hour long.. It felt like ten minutes the way it just sucks up your attention. Absolutely amazing quality! If chemistry classes were like this in my high school I would have been a chemist right now.
I love that the Ammonium Perchlorate mix burned for exactly 2 minutes. There is always conformity to be found among chaos
Great video, as always!
Wow! I love it! The slow burn was absolutely impressive. This would be great for a glider. I always wanted to make a couple top fuel dragsters and lined them up head yo head with small fast burners. Kinda replicate a quarter mile drag.
i still have the ''Jetex" engines. doubt anyone can still get the fuel pellets. they are prolly antiques now.
Thanks for the video ! It brought back some good childhood memories of model rocketry ! Very interesting tutorial and meticulous craftmanship in how you make your motors ! :- D
You are the best when it comes to explaining what you do. Thank you!
Very rarely can someone captivate my attention for so long ( i normally realize that they actually know less then i do lol ) but you sir are a different animal. I like your broad knowledge and the way you have to clearly communicate it. We feel your passion, and it shows in your videos. Thanks you so much and Merry Christmas to you too!! Looking forward to see the motors thrust test result!
Yeah, I don't watch Clip-Share to learn from myself.
I agree with your comment.
I love your content it definitely keeps me entertained thanks for the work you do and the educational content you put out there
A great video. Was lots of fun to watch. Thank you! I’d love to have a shop setup like yours.
Outstanding,great presentation.Some small things to consider ,glycerin comes in quite many grades of dilution,80% product is glycerin ,90% as well,anhydrous glycerin is also glycerin.Ammonium nitrate commercial grade can be a mix of NH4NO3 and (NH4)2SO4,so it is important to know the quality of ingredients.Centering a rod/pipe in the the hull of the rocket engine is easier with some kind of of centering jig.The info about addition Fe2O3 and NH4ClO4 is quite "enlightening".
Had fun with Estes rockets as a kid and later got my daughter into it as well, but my dad always used to say that he refilled his own rocket engines back in the day. Finally got to see what's involved. Thanks much.
Great video. Very thorough. I used to make sugar rocket engines when I was a kid. I like that you played around with different oxidizers and catalysts.
Clip-Share algorithms may not prefer your super detailed longer videos, but we do, thank you for putting us ahead. Respect..🙏
Wow I sure wish this would have been available when I was exploring rockets back in the 70's. Great presentation ..
Everything about this channel is amazing. Thank you for this material.
What a great science lesson, and video!
Your commentary is concise, and kept my attention for the whole video!
Thank you for these very interesting videos, much appreciated. Love it
Utterly magnificent lesson. Thank you so much!
Love your detail and passion for engineering and science. Thanks for another excellent video!
I’m almost 50 years old and it’s amazing how you have inspired me to take up chemistry as a hobby now at this stage in my life. Thank you and please keep them coming.
Great!
Will do.
This gentleman is teaching engineering for free. such a valuable lesson with practicals. WoW!!!!
My respects and full support to this guy, his videos are extremely high quality, in both production and information, congrats and thanks
Thank you.
Great video, phenomenal teacher! I will be watching more. Thanks!
Very clean lab, and great information. Thanks for doing this.
This channel has to be the best for us slightly unhinged nerds and geeks who just love to experiment. I've even done some of this stuff myself, but nowhere near as well! He's like the dad we all wanted growing up.
Is it too late to be adopted?
@M Brew :) :) :) :)
Not just nerds....
LOL "Unhinged" is definitely a prerequisite for this activity!
Fascinating. You put a lot of effort into your production.
Superb teaching skills, in a fair world every kid would grow up with teachers of this quality.
First time on this channel, and I had to subscribe. This guy is a spectacular
natural teacher.
Great technique and very thorough. I really appreciate the research you've put into the small additions that increase your yield. The only thing I would suggest as a change is for you to brush on your contact cement. You could even do it with a finger. What that does is substantially reduce your wait time until tacky But will also reduce the amount of globs that occur that might fall off into your flash powder.
The other thing you might want to think about is having a flash powder plug That pushes down to the bottom of the burn channel. The only reason for this would be less assembly time.
Perhaps shreading a cotton ball, mixing a small taste of flush powder and acetone and then impregnating the cotton with the flash powder paste. You could then either insert a pinch of impregnated cotton and to the rocket engine followed by a fuse or you could wrap a pinch of impregnated cotton around the end of the fuse then insert the fuse to the bottom while twisting the same direction as the cotton twist and then twist the fuse the opposite direction to relax the cotton bound cotton fibers - which in theory would allow the infused cotton and the fuse to hold. 🤷♂️
The reason for the acetone is to make the paste but then allow a rapid evaporation leaving the flash powder behind.
This channel is amazing. Thanks so much for this and your support of the NAP.
So far, this is the most informative video I have found since making my own sugar motors. Very professional, not all hyped up. It's like watching my old physics instructor but this time I'm totally interested! :)
Video on making the engines was extremely interesting and informative. This one was more "gee whiz"; I was expecting time-force graphs, "after action" examination & discussion, future trials. The sparks being ejected are (probably) either molten fuel droplets or the nozzel burning out - either will reduce performance.
This video brings back memories of my JROTC training in high school. We spent about a week on rocket engines. One thing I remember is you can change the shape of the central void in the grain to vary the burn rates. That was almost 40 years ago, so I don't recall any specific shapes in the text. I can visualize how a cross or star shape would burn differently than a round hole would though. Great video! 👍👍
End burn without a hole is slow, round hole is fast, a star is fastest because of more surface area.
Hello Sir! i just stumbled upon your page. I absolutely love your technical descriptions for everything you do. i have been in hobby pyro for all my years. professionally licensed shooter when i turned 18. over 20 years i have been exparimenting and dabbling in alll sorts of different compositions. your channel is inspirational and i will continue to watch and learn! thank you
So much thanks, what you do is invaluable, great work from Australia
Fascinating subject matter, learn a lot from your videos (liked and subscribed) Wondered what would happen if one were to make different mixtures for one engine (like a multi-stage i.e fast burn then slow burn motor) would there be any chemical interactions between mixing these different types of blended fuels a layer at a time in the same rocket.) Hope your doing well and look forward to more products and videos in the future. Best regards.
I appreciate yours and your son's enthusiasm in your projects and dedication to completeness.
I've not seen anything like this before, really informative and interesting. I quite like the engineering side of this. It would be great to see these rockets in flight.
Thanks!
This is the first of your videos I've viewed. What a tremendous resource!! Thank you for going through all the science. This is absolutely awesome!!
Welcome!
Since I watched your video on creating graphene in a quartz tube with catbon black, copper wool plugs and a self-designed 'Doomsday' capacitor-based power supply, I have been utterly captivated by your extraordinary breadth and depth of scientific understanding. It is clear that you do these videos out of a passion for teaching, rather than out of any need for income, as it strikes me that your skills are commercially valuable in the extreme. I have been glued to your channel from the first viewing, cemented when I watched the one on resonating panel loudspeakers (as a lifelong audiophile and previous owner of similar designs, as well as electostatic panel speakers - Quad ESL). You make everything so easy to understand - more so than anyone or medium has before. Thank you so much and, please, keep going.
Thank you!
Awesome Video your descriptions and explanations made it very easy to understand. I haven't made a sugar rocket in years but this makes me want to start all over again.
Thanks for making this video, you explainded all the concepts very well, good job.
Probably the most intuitive introduction to practical rocket science one could find online.
Want a much more detailed explanation of solid fuel rockets: clip-share.net/video/jATkV8HE2sQ/video.html
Watched it. its not a detailed explanation at all. Just a consumer news service level record of a test day for SLS Solid Booster. The only part I found interesting was the 2 minutes showing the geometry of the grain port... clip-share.net/video/jATkV8HE2sQ/video.html
@Ben Coman I found it to be laced with design tidbits throughout, but no, it is not a how to build your own with blueprints and fuel formulae.
If all other viewers are interested in watching is the lighting of the candle, here is a much shorter video: clip-share.net/video/E3cPKgFKe0Y/video.html
@Ben Coman What part of "intuitive", "introduction" and "practical" you don't understand? I can help.
Im not a science geek or tech savvy, but this is interesting to watch and easy to understand(mostly)
Dude is my dream future self. Soo dedicated to science he makes almost everything himself from scratch and shows it to the world
I have an idea.
The last 25% of fuel is a slower burning mix with a colorant added to create a visually pleasing launch that will start out slowly then accelerate once it leaves the pad. The first propellant injected is a slow slow burning smoke mixture that will leave a trail all the way to the ground to aid in locating.
I think you have the best Clip-Share channel for (DIY) tech! I think if you put your mind to it you can do whatever project you want. I really like the broad information. Thank you so much!!
Can't wait to see him make a homemade fusion reactor.
Always a good day when tech ingredients makes a new video!
I use a drill for mixing epoxy which obviously creates loads of bubbles which are degassed by drawing the epoxy into a 60cc syringe but only a small amount, then capping the tip and pulling a vacuum with the rest of the plunger travel. I do this several times and it only takes a few seconds. Extremely fast way to get all the steps done with perfect mixing.
What a great teacher you are, thank you.
I love the diversity of your video and technical content
A very fine video. You are a great technical speaker. The pace was great. The presentation was clear. Well done!
No BS with this channel. All business. I respect that a lot. Thank you for the excellent content.
One of my best friends in middle/high school had a dad that worked for Loctite. He legitimately had every single Loctite product in his garage that the company made for the previous 35 years. I never paid for a single adhesive or epoxy until I was in my 20s. But I think I could watch one of these videos specifically about the various epoxy types, mixes, ratings, additives, and some unique uses for them all. For some reason, the older I get, the more I appreciate random building materials. In fact, this makes me want to make a rifle out of nothing but epoxy.....
Thank you for this knowledge, it is so fun in life to learn new things. You are a great teacher.
Having voiced my concern and surprise about ammonium perchlorate, I have to admit that this guy or outrageously detailed, and well spoken. I appreciate this.
Awesome vid,I,ve heard of these sugar motors for years,never realized how complex they were,like you say,make 10 at a time,Great commentary and videography,well worth a subscribe,always wanted to know how to make a rocket motor,very well explained and in great detail,I only subscribe to channels with something special and great character about them,you have this,look forward to seeing more of your vids,Awesome. Best wishes to you and all your viewers and subscribers, from, Auckland, New Zealand 👑🔥⭐🏅👍✅💯%❤
Just wonderful. Put aside a moment the introductions to some of the aspects of engineering and science........the patience, planning, homework, attention to detail, subtlty. If these are all a student absorbs, they have learned some very essential traits I hope are learnable. I'm certain I'm overlooking some. Thank You! Keep up the excellent work.
Great Video! Thanks for including the google doc with the formulas for quick and easy reference. I've wanted to try this since King of Random did it so long ago, but never got around to it. Keep the pyrotechnical content coming please :)
Ive been brainstorming a rocket glider for months. I hadnt thought about using a slow burn motor before! Thanks!
I absolutely love your analogy and way to "visualize " how a rocket works. You are an absolute Clip-Share legend!!!
Thanks!
I would love to see a slow burning outer grain and a medium inner grain in a larger tube
As a lifelong 'model' rocketry enthusiast,, I found this very informative. Like the shout out to the other channels to which I already subscribed. 😀
Great stuff, yet again. I'm really enjoying this channel, and want to see subs go through the roof. Which sounds like a boating nightmare.
It's not often a video of this length keeps my attention without skipping bits, but I watched every second of it. This is quality. Thank you.
Great videos, love your work.
If you were my teacher in high school I would be working for NASA. If you were my coach I'd have been on a team that won state every year probably and the entire team would have turned pro. The most natural effective communicator I've listened to.
Thank you for sharing your time and knowledge. I really loved the video and if I had you as a science teacher I would have done much better because you have an awesome manner when demonstrating or explaining everything. I hope you and all those hear or dear to you stay healthy and happy in the future.
Thank you.
Excellent video very educational and specific, thank you very much.
Thank you. Really enjoyed that, technical enough for us newbies without a BSc!
Always appreciate when someone way way smarter than you decides to take the time and care to teach, simply because they want to share the exciting things they know with you.
Weak
The depth and breadth, the diversity of this man’s scientific interests and knowledge, and the precision and with which he investigates the topic at hand, and the time and monetary investments made, are truly staggering and shine ✨ like the sun.
You, Sir, are the definition of “polymath”.
BUT wait… it’s not only that, it’s the clarity and utterly pedantic, uncompromising precision with which he and his team (son?) film and document the subject matter, which should have won them awards WAY WAY outside the mere Clip-Share sphere. He transcends Clip-Share but I thank GOD he is here and showing us things.
When I think of REAL scientists and engineers, the sole two channels imprinted on my mind are “Tech ingredients” and “Smarter every day”
We all wished for teachers like You. Now I am old and not as interested like a kid but I still wish for more people like you with passion and great skill in telling what you mean to convey in understandable and interesting manner.
I don’t watch a lot of videos longer than an hour (I mean WATCH, not listen to in the background while I’m showering) but I did this one. Made me a little late to the gym but I couldn’t stop. I used to make little rockets when I was a kid, would have been a lot safer if we had access to the information you presented. Thank you for the clear, interesting explanation of the construction of a solid rocket motor. A little beyond the heads of paper matches packed into an empty CO2 cylinder ignited by half a firecracker stuffed into opening. Shot out of a piece of pipe.
Wow! Amazing contents. Thank you. Writing less as I’ve a lot to thank you for. You are inspiring the next generation and peers. 🔥
Thank you!
Amazingly clear explanations!!!
It's always a great day when Tech Ingredients releases a video! My Curiosity runs wild about running thrust test on each of those engines on the Jet Engine thrust measuring device. Maybe even build a very large Engine and measuring the thrust. That would be an amazing video.
I LOVE YOUR CHANNEL! Thank you for your creation!!
I would like to restart my hobby once I get done moving. I would like to start at class 1 rockets and data collect and make the rockets smart. Recently I just came across your videos and they are very inspiring and I cant wait to start up again. So right now I am studying. Thank you for all you do!
fantastic video, thanks for your efforts!!!
