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!

I watched this on Christmas Eve, and here in Sweden we give the gifts on this day, and this video was like a real good christmas gift. I was like a kid, "yes, yes, rockets! Yippie!!".
I have to agree twice cause in Germany chrismas eve is the night that counts - for adults and children. And same for the video that I had seen in the hour it appeared and loved the progress and evolution in all details. Spend the whole video to make sure to understand the big points. But a lot of people will run in trouble here due to the chemistry if you order too much and online cause what is great to power a rocket is also great for a bomb and we had a swedish guy buying ingredients online due to his hope swedish restrictions would end at the border. But seem to be EU regulations behind a curtain that kicked the trigger.
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.

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.
Thanks for showing safe procedures for handling these materials. Some friends were careless making rocket candy at the beginning of the year and started a fire.
igniting any experimental motor with a fuse and run is probably one of the most dangerous things that can be done in rocketry and has resulted in numerous injuries and deaths.
I was in a rocket club when I was in high school sixty years ago. You remind me of the very excellent instructors there. We even had a liquid fuel engine that ran on acetone and compressed air. It was pretty heavy, so it never went very high, but it had a gyro and a gimbaled nozzle. That experience was life changing for me. It didn’t just teach me math, chemistry and rocketry, it taught me confidence, caution, and, above all, how to think. Your site is right up there with the Royal Academy. Thanks so much for this. Really excellent.
I love that you said to use a vacuum when machining the graphite nozzle and immediately thought to specify "vacuum cleaner". Because this is EXACTLY the kind of channel where we might see exotic vacuum machining processes being applied!!! You guys rock.
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.
Have you watched John Dobson build a telescope from scratch, grinding down a piece of glass by hand. The video is here on TH-cam and well worth a watch, th-cam.com/video/snz7JJlSZvw/w-d-xo.html
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.
First video I've seen from this channel. You're an incredible speaker. I can't quite describe it, but the way you've essentially spoken for an hour straight without too many cuts and in such an engaging, easy to understand manner is amazing
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.

I live in VietNam where Sparklers, those hand-held party items, were legalised only a few years ago. Forget fireworks, they are for the military. This excellent series has provided resources that enable us to do things that escaped the attention of law makers. Our group now has science camping weekends where go to so remote area and literally have a BLAST! We made our Man in Space with a camera, and together with information from other TH-cam series, coupled with yours, we have been able to build rockets. We take your videos, add a visual track of your words in Vietnamese, and away we go! Personally I am involved in lasers used for various production processes, but your sound series have been used in our laser range high in the mountains along the Laos border. Thank you for your great work and the stimulation it provides to curious young minds on the other side of the world.
when ever I see videos of someone who is quite big on youtube trying to make sugar rocket motors, they tend to make a lot of mistakes or just have poor methods. you pretty much nailed everything. only thing i can say is give tips for improvements. you can use a few drops of sodium laureth sulphate/ SLES (the surfactant in shampoo and soaps) to thin the fuel as much as possible. Richard Nakka has a video detailing its use. You may also want to try making a reusable motor out of metal. this will allow you to only need to make fuel grains for each firing. With regards to storage, its best to store it in an air tight container with desiccant to keep the fuel dry otherwise it will pull moisture. the only fuel I've ever used that just does not pull moisture uses erythritol. Another thing is that fuel with iron oxide in it does not store long term, it does something to it that causes the motor to always explode. anyways. good video
@@mojaverockets I'd be tempted to make a core alignment jig. The reliability of these engines is contingent on many things. One of which is the reproducibility of the core. Simply jamming it into the molten mix will, eventually lead to a CATO of the engine at worst, at best unreliable motors. Also, it would have been nice to weigh the test composites to at least increase the chances of comparing apples to apples :) Anyway, always enjoy your work. Stay Safe and Stay Well.
Every night I drive my nephew to work 3rd shift. He is in early 30s and still wakes up 30 before work. The whole time I talk about different channels I watch and don't shut up. He is a real smart kid and I know he would love to tell me to shut. You have given me weeks worth knowledge because I was getting low on subjects. Thanks for the video
When I was a kid in the early 80's I I pressed sugar + potassium saltpeter with a hydraulic jack into my rocket engines, this method blow my mind. You are the best !
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! :)
So informative, it was sad not really being taught chemistry and so much of the world being confusing early on. Amazing creators like you give so much understanding to the people in the world it's truly incredible.
How nice, back in the day we did not have all this fancy modern way of building model rocket motors. Our casings were roll with glued paper bags over maderals. They hardened after a few days, the had to be inspected and sized, plugs and nozzles were made from pounding fire clay and grog with homemade maderals, all our tools had to be made as you could only order the chemicals, scales, and things already available for other uses. It took much longer to do this and then build our own Dinamo meters to test thrust out put, but that only came after hours of testing motors under ground due to many failures. It was fun and I put many years into this until I had a reliable safe motor to use. What you have to now and just order is incredible to me. I wish I could start over, but I have to many medical issues right now. Good video, nice safe shop you have thanks for passing this down to next generations of young people. I still hold a certification in High Power Rockets, mostly as a donation. Although I might attend the LDRS in Black Rock if I am well enough. Thank you.
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!

@@sporkeh90 hahaha yeah mate that Rabbit hoooole is deeeeep asf😂🙉🙈 But worth exploring!

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 :)
What got my attention was that you seemed to allude to the method of layering the different regression mixtures so a solid fuel rocket can lift suddenly, then accelerate slowly before hitting the fast regression mixture in thinner atmosphere.
I suppose it could be achieved, if You would have signigicant diameter of the rocket (quite big is necessary) and then wou would use some internal tube every time in different diameter to our the next layer of the fuel. PRocess would take few days, but it's achieveable.
That would work but is not relevant to a motor that could (easily) be built that way. A serious issue with the plain hole through the middle is that as it burns the surface area increases, increasing gas production and therefore thrust. The "simple" way to get round this is to use a star shaped hole, the surface area remains constant, but would make layered manufacture very very tricky. Having said that though, a layered approach would be another solution. One construction technique could be like dipping candles. Each dip in hot wax adds a thin layer.
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!
@@fkujakedmyname As a design engineer I appreaciate the thought process that goes into their design descisions. I can see you may have passed high school. did you get much further.
I'm surprised that you didn't mention The Elemental Maker, he's highly knowledgeable on this subject. Also, I see I'm not the only one who uses the mill table as a workbench!
I did so enjoy your presentation. Good job. Started trying to construct rockets in 1957. We would skim match head material and place it in small tubes of paper. Do not think we ever got lift off. 73 years of age now and fortunate to be here, intact. Couple years later we did a match head piece of 1/2 inch copper tube. Got our attention. Even did some stupid shit in VN. Big fan of black powder as well the flash powder. Grew up with original Cherry Bombs, M-80's. Still have some supplies, scales, grinders. Getting warm in my area, so many projects on my list. In highschool we were scraping Pidgeon shit off tree limbs for nitrate. Enjoyed your information as well the delivery. Thank You.
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!
It's fairly easy to get it outside of commercial use, but most suppliers still want see some credentials just to be reasonably certain that you're not some random nut job that will cause another round of regulatory scrutiny. I know a chemist that got a visit from the FBI for ordering oxidizers, and it was probably just a routine audit and their name fell out of the hat, and nothing happened. But they are watching and companies do want to protect themselves from liability.
Benn watching TH-cam videos since it's inception. I like how your just about the ONLY 1 who does this step by step, without that monotone, virgin, clinically depressed cereal killer kind of voice. And ur the only 1 I'm actually going to donate to.
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 :)
Thank you so much, I'm so glad to have stumbled upon you. I missed my calling in high school because I was lazy. I have resparked my imagination and I'm gonna change the world with some new ideas in physics and chemistry. I'm 59 years old and I want to Set an example for others 😄I'll at least change the outlook of my family and friends
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.
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.
8:00 - in all the years I've been watching science and rocket videos on TH-cam, you're the first person I've seen who's explained rocket thrust in this manner. Everyone else just talks about Newton, conservation of momentum, reactions, etc. None of this actually explains thrust, this explanation does. I first came across this explanation in a children's book on space flight - I think it was in 1968 or 69 (not a coincidence - everyone, including 7 year olds, were crazy about space flight and rockets back then). The thrust would be the area of the opened door multiplied by the pressure (or pressure differential) in the room. Excellent!
This brings back old memories. As Kids, we use to only use ~3 to 4" of canon fuse, to get away. Now, that I'm older and slower, that 7" length sounds about right. Flash powder was our standard powder for firecrackers. For larger ones, we slowed down the burn a bit. But I use to tweak the fuel/oxidizer mix, empirically, by examining the residue. Use to get a good thump out of it, when optimized, that would knock over a can a foot away.
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.
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! 👍👍
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 wish I'd had teachers like you when I was in school as a kid! You make everything so interesting. Plus, your knowledge and demeanor makes one want to hear and learn more! More subjects and more in depth. You make things understandable. The problem was and is, that my brain is wired a bit differently, as no one understood that my problems in school were mainly due to that little known (at the time) ailment called dyslexia. I did not know why I hated school, or why things just did not make sense. I was schooled in the 60's and 70's so I was labled as a student who was lazy and just did not apply himself. Things on paper (lessons, school books, etc.) were hard to understand. My brain just did not jive with what was on paper. As I grew into adulthood my brain worked those things out and made connections in a more round-about way. I found that hands-on learning was the way for me to learn. The more mechanical a problem was, the easier it was to solve. I found that I was extremely inclined mechanically. I still have no desires to be a rocket scientist, and hate mathematics, but I do love learning from you and your channel! You make learning exciting! Thank you, for just being you! 😊

People often underestimate just how much energy is stored in regular Sucrose. Your typical kilogram bag of sugar contains 17 mega-joules of molecular energy. That’s a little over four times the energy stored in a kilogram block of pure TNT… Even if Sugar doesn’t burn when you put a flame to it, that obviously doesn’t mean that the retained energy can’t be utilized. It just needs an oxygen-rich environment. Like when mixed with an oxidizing agent or mixture of oxidizers with a decomposition catalyst…
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 think he was referring to all the epoxy and epoxy related items he has accumulated over the past few years. I would assume he needed quite a bit for his 'Drone Rotors' projects from 3 years ago.
Amazingly informative - thank you. I found the part about the catalyst and the retardant fascinating too - and after you explained why there would be occasions when you would want a fast regression initially and then a slower one, I wondered if you had ever thought of making a double stage solid rocket - especially as you have the test rig to be able to see if it "worked as planned". This might only be being viable with a larger size to give you the extra space inside to play with though but I was thinking if you started off exactly as shown above and made a slow regression rocket but with a VERY large centre hole - so that once the over-sized former was removed, you could then pour in the faster regression mixture. Then once the smaller former was finally removed, you would have an initial fast regression layer - then after a few seconds rapid initial burn, it would progress to a much slower, but longer endurance one. Forgive me if I have made some very obvious errors (and you may already have done this on another video I have yet to find!), I stumbled over your page and became captivated but have yet to properly digest all the information provided, awesome video, thank you. I have liked and subscribed :)

And same for the video that I had seen in the hour it appeared and loved the progress and evolution in all details.
Spend the whole video to make sure to understand the big points.
But a lot of people will run in trouble here due to the chemistry if you order too much and online cause what is great to power a rocket is also great for a bomb and we had a swedish guy buying ingredients online due to his hope swedish restrictions would end at the border. But seem to be EU regulations behind a curtain that kicked the trigger.
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.

Thanks for showing safe procedures for handling these materials. Some friends were careless making rocket candy at the beginning of the year and started a fire.
igniting any experimental motor with a fuse and run is probably one of the most dangerous things that can be done in rocketry and has resulted in numerous injuries and deaths.
I was in a rocket club when I was in high school sixty years ago. You remind me of the very excellent instructors there. We even had a liquid fuel engine that ran on acetone and compressed air. It was pretty heavy, so it never went very high, but it had a gyro and a gimbaled nozzle. That experience was life changing for me. It didn’t just teach me math, chemistry and rocketry, it taught me confidence, caution, and, above all, how to think. Your site is right up there with the Royal Academy. Thanks so much for this. Really excellent.
Thanks!
That's a high compliment and very appreciated.
I love that you said to use a vacuum when machining the graphite nozzle and immediately thought to specify "vacuum cleaner".

@Ivan Jakanov Its literally rocket science
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.
First video I've seen from this channel. You're an incredible speaker. I can't quite describe it, but the way you've essentially spoken for an hour straight without too many cuts and in such an engaging, easy to understand manner is amazing
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 .
Yeah, but given that he's a white male, the "woke" cult driving our cultural norms would have considered him as evidence of racism & "toxic masculinity", and fired him for someone who is far less competent at teaching/inspiring students, for the sake of "diversity".
Bill Entley. Best teacher in my entire academic career. Taught high school physics, and you could tell he actually cared about making you LEARN something and not just giving you a grade. You could also tell he was one of those kind of people who was so smart it was kind of scary. And also funny as hell. And ugly as a can of smashed assholes.
One of the few creators that gets an automatic like before I even watch the vid. Huge amount of respect for this channel.

We made our Man in Space with a camera, and together with information from other TH-cam series, coupled with yours, we have been able to build rockets.
We take your videos, add a visual track of your words in Vietnamese, and away we go!
Personally I am involved in lasers used for various production processes, but your sound series have been used in our laser range high in the mountains along the Laos border.

Thanks.
Did you watch our earlier videos on lasers and laser scanners?
when ever I see videos of someone who is quite big on youtube trying to make sugar rocket motors, they tend to make a lot of mistakes or just have poor methods. you pretty much nailed everything. only thing i can say is give tips for improvements. you can use a few drops of sodium laureth sulphate/ SLES (the surfactant in shampoo and soaps) to thin the fuel as much as possible. Richard Nakka has a video detailing its use. You may also want to try making a reusable motor out of metal. this will allow you to only need to make fuel grains for each firing. With regards to storage, its best to store it in an air tight container with desiccant to keep the fuel dry otherwise it will pull moisture. the only fuel I've ever used that just does not pull moisture uses erythritol. Another thing is that fuel with iron oxide in it does not store long term, it does something to it that causes the motor to always explode. anyways. good video
@NC Dave different type of motor.also thats the worst way to make a rocket motor
using fuse to ignite 'and run' from any experimental rocket motor is flirting with danger and how many are injured/killed
@@mojaverockets I'd be tempted to make a core alignment jig. The reliability of these engines is contingent on many things. One of which is the reproducibility of the core. Simply jamming it into the molten mix will, eventually lead to a CATO of the engine at worst, at best unreliable motors. Also, it would have been nice to weigh the test composites to at least increase the chances of comparing apples to apples :) Anyway, always enjoy your work. Stay Safe and Stay Well.
@NC Dave just because your big on TH-cam doesn’t make what your doing safe
Honest could watch you explain anything. Really good style, explains things slowly and thoroughly, no bs, just the facts. Well done.

I wonder about a capacitor discharge to ignite the rocket
How nice, back in the day we did not have all this fancy modern way of building model rocket motors. Our casings were roll with glued paper bags over maderals. They hardened after a few days, the had to be inspected and sized, plugs and nozzles were made from pounding fire clay and grog with homemade maderals, all our tools had to be made as you could only order the chemicals, scales, and things already available for other uses. It took much longer to do this and then build our own Dinamo meters to test thrust out put, but that only came after hours of testing motors under ground due to many failures. It was fun and I put many years into this until I had a reliable safe motor to use. What you have to now and just order is incredible to me. I wish I could start over, but I have to many medical issues right now. Good video, nice safe shop you have thanks for passing this down to next generations of young people. I still hold a certification in High Power Rockets, mostly as a donation. Although I might attend the LDRS in Black Rock if I am well enough. Thank you.

I'm glad to see you've reached your 500k mark. Congrats and deserved.

Except knowing the difference between cheap and inexpensive
What got my attention was that you seemed to allude to the method of layering the different regression mixtures so a solid fuel rocket can lift suddenly, then accelerate slowly before hitting the fast regression mixture in thinner atmosphere.
I suppose it could be achieved, if You would have signigicant diameter of the rocket (quite big is necessary) and then wou would use some internal tube every time in different diameter to our the next layer of the fuel. PRocess would take few days, but it's achieveable.
That would work but is not relevant to a motor that could (easily) be built that way.
A serious issue with the plain hole through the middle is that as it burns the surface area increases, increasing gas production and therefore thrust. The "simple" way to get round this is to use a star shaped hole, the surface area remains constant, but would make layered manufacture very very tricky.
Having said that though, a layered approach would be another solution.
One construction technique could be like dipping candles. Each dip in hot wax adds a thin layer.
The use of layered propellants with different burn rates and ISP is used in solid rocket motors industry, generally referred to as dual thrust.
Layered propellants and combustion chamber designs are what the big boys use to achieve necessary thrust curves.
This was phenomenal. The camera zoom and focus were great. This was an extremely professional video and incredibly informative!
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!
Your long videos are fine because you don't pad it out with pointlessness, every minute is worth watching.

Also, I see I'm not the only one who uses the mill table as a workbench!
I did so enjoy your presentation. Good job. Started trying to construct rockets in 1957. We would skim match head material and place it in small tubes of paper. Do not think we ever got lift off. 73 years of age now and fortunate to be here, intact. Couple years later we did a match head piece of 1/2 inch copper tube. Got our attention. Even did some stupid shit in VN. Big fan of black powder as well the flash powder. Grew up with original Cherry Bombs, M-80's. Still have some supplies, scales, grinders. Getting warm in my area, so many projects on my list. In highschool we were scraping Pidgeon shit off tree limbs for nitrate. Enjoyed your information as well the delivery. Thank You.
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!
It's fairly easy to get it outside of commercial use, but most suppliers still want see some credentials just to be reasonably certain that you're not some random nut job that will cause another round of regulatory scrutiny.
I know a chemist that got a visit from the FBI for ordering oxidizers, and it was probably just a routine audit and their name fell out of the hat, and nothing happened. But they are watching and companies do want to protect themselves from liability.

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.
8:00 - in all the years I've been watching science and rocket videos on TH-cam, you're the first person I've seen who's explained rocket thrust in this manner. Everyone else just talks about Newton, conservation of momentum, reactions, etc. None of this actually explains thrust, this explanation does. I first came across this explanation in a children's book on space flight - I think it was in 1968 or 69 (not a coincidence - everyone, including 7 year olds, were crazy about space flight and rockets back then). The thrust would be the area of the opened door multiplied by the pressure (or pressure differential) in the room. Excellent!
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!
This brings back old memories. As Kids, we use to only use ~3 to 4" of canon fuse, to get away. Now, that I'm older and slower, that 7" length sounds about right. Flash powder was our standard powder for firecrackers. For larger ones, we slowed down the burn a bit. But I use to tweak the fuel/oxidizer mix, empirically, by examining the residue. Use to get a good thump out of it, when optimized, that would knock over a can a foot away.
we used to make a gasoline cannon and launch full soda can...

My favorite cooking show.
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.

I wish I'd had teachers like you when I was in school as a kid! You make everything so interesting. Plus, your knowledge and demeanor makes one want to hear and learn more! More subjects and more in depth. You make things understandable. The problem was and is, that my brain is wired a bit differently, as no one understood that my problems in school were mainly due to that little known (at the time) ailment called dyslexia. I did not know why I hated school, or why things just did not make sense. I was schooled in the 60's and 70's so I was labled as a student who was lazy and just did not apply himself. Things on paper (lessons, school books, etc.) were hard to understand. My brain just did not jive with what was on paper. As I grew into adulthood my brain worked those things out and made connections in a more round-about way. I found that hands-on learning was the way for me to learn. The more mechanical a problem was, the easier it was to solve. I found that I was extremely inclined mechanically. I still have no desires to be a rocket scientist, and hate mathematics, but I do love learning from you and your channel! You make learning exciting! Thank you, for just being you! 😊

39:00 Might be cool to add a centering ring to that insert so the plunger gets a straight shot at the bottom
an indention in the plug would achieve that same goal . I did think that about the only haphazard process here. I think the hollow part, if off kilter would radically affect trajectory, maybe not.
and I say maybe not, due to the nozzle. could be that on the back side of the nozzle the direction of the pressure is negligible.

People often underestimate just how much energy is stored in regular Sucrose. Your typical kilogram bag of sugar contains 17 mega-joules of molecular energy. That’s a little over four times the energy stored in a kilogram block of pure TNT…
Even if Sugar doesn’t burn when you put a flame to it, that obviously doesn’t mean that the retained energy can’t be utilized. It just needs an oxygen-rich environment. Like when mixed with an oxidizing agent or mixture of oxidizers with a decomposition catalyst…

Oh, so we’re gonna talk about the TR-3B now?
"... and lube" 🤣🤣🤣
@@ExplosivesLaboratory I don't know what that is. So yes please 😂
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.
22:45 “I have everything related to epoxy.”
Weird flex, but ok.
Its like 24 inch rims but for scientists.
I think he was referring to all the epoxy and epoxy related items he has accumulated over the past few years. I would assume he needed quite a bit for his 'Drone Rotors' projects from 3 years ago.
he did a series on epoxy previously.
those who like epoxy, like it a lot. my grampa was an epoxy fanatic.
He sells the thermal epoxy they made in one of the videos to people who don't want to buy the strange ingredients (graphene etc.)
Amazingly informative - thank you. I found the part about the catalyst and the retardant fascinating too - and after you explained why there would be occasions when you would want a fast regression initially and then a slower one, I wondered if you had ever thought of making a double stage solid rocket - especially as you have the test rig to be able to see if it "worked as planned".
This might only be being viable with a larger size to give you the extra space inside to play with though but I was thinking if you started off exactly as shown above and made a slow regression rocket but with a VERY large centre hole - so that once the over-sized former was removed, you could then pour in the faster regression mixture. Then once the smaller former was finally removed, you would have an initial fast regression layer - then after a few seconds rapid initial burn, it would progress to a much slower, but longer endurance one.
Forgive me if I have made some very obvious errors (and you may already have done this on another video I have yet to find!), I stumbled over your page and became captivated but have yet to properly digest all the information provided, awesome video, thank you. I have liked and subscribed :)
I was thinking the same thing
Youtubing is hard. You're doing it well sir! Subbed!
I respect the fact that you showed your troubles. That really made the video stand out to me.
Moonshine, Rockets, speakers out of balsa wood! Better than any BS on cable and it's educational. If science was like that in school back in the day I would have gotten straight A's. Love what you do , thanks bro you rock!
