"if you wanna get your ass to Mars, Your gonna use a liquid rocket engine" - Noted :D
It's an Arnold Schwarzenegger (Quaid) quote from Total Recall.
For maximum thrust combine carbonated liquids and various laxatives
seriously though now i'm curious if you can use butane/propane or gasoline and hit it with NOS for more lift
And here I thought it was a word play, and he said "If you want to get your MASS to Mars". Damn.
mars is rich on chlorates... it will just be a pit-stop planet...
Tech Ingredients: Careful, methodical, safety-conscious, stoichiometric
Integza: I'm gonna run pressurized O2 and propane into a 3d printed rocket inside my house!

Other UA-cam Channels: Don't Try this at home.
Tech Ingredients : Here's exactly how you try this at home
But with every possible detail, safety precaution, process, theory, and implementation included, hence still making it a lot safer than 99% of other YT science creators who dont even understand what they are doing and are just recreating something cool they saw in another video.

I completely agree and it becomes fractally true again to your comment.
I appreciate the lengths taken to explain the details needed to achieve a successful result. This goes for all the projects I've enjoyed on your channel. Thank you. ✌
You are my favorite scientist/engineer/Inventor/narrator/teacher. It's like we are on the same wavelength of thought. I identify as a know it all, but I learn so so much from you and it's great. #1 fan *Tech Ingredients*

You’re by far the coolest dude I don’t know.
Don't even need to wait for this to start playing to give a thumbs up because I already know I'm going to love it.
says, "on 3."
goes on 0.
It's like rock paper scissors vs rock paper scissors shoot.
On three: meaning, I am starting on the number three. I am now on three... 3, 2, 1, 0. Zero being the go word.
That's not usually how it works. "to go on 3." means that you go on 3. "1 2 3!" he just counted the wrong way.
I guess internally he's always thinking what he says at 37:14 but then shortens it to "on three".
It's a common science thing. Number of that that start listing points when talking...
one: blah blah blah,
two: rhubarab, rhubarb...
and C: blah, blah, rhubarb.
In the military, we said "IN 3", meaning after a 3 second count. I suspect "ON 3" is a misnomer.
When coordination was needed across a team, the controller would shout "IN 3" and everyone else would shout it back. Then would come "Fire in the hole!", then the count would start. When counting down, saying "Zero" marks the end of the third second.
i don't see it mentioned anywhere, so just a small note: Specific impulse is NOT unitless but is "Seconds" instead :)
Awesome video, as alwasy!

Since I was child I always enjoy watching science demonstrations, Dr. Julius Erving was a favorite. I enjoy your demonstrations as well. I'm 70 and still learning.
Your videos have uncovered for me so many areas of practical engineering already - each time with in-depth, engaging explanations. I also appreciate how you always dub all the measurements in imperial and metric wherever it makes sense.
I love your detailed explanations. I used to experiment with hybrid engines in the early 2000's and the problem I was trying to solve was a non pyrotechnic ignition. At the time, hybrid rocket engines were using a fuel grain to start the process. Instead of a nozzle, I made an injector out of a "T" fitting with a copper rod going down the center of the "T" fitting, closed off with a compression fitting to insulate and attach the copper rod. The nitrous came through the center of the "T" fitting and exited out the other end of the fitting, which was screwed onto the engine bulkhead. Now, a high current plasma arc was initiated between the copper rod the "T" fitting. The copper would erode and vaporize under the plasma current. Plasma vaporizing copper creates a combustion process and produces a bluish purple flame. Copper is combusting with the oxidizer before it enters the combustion chamber. Copper is also a catalyst for nitrous oxide and should cause the nitrous molecules to split, produce heat to start the combustion process. But then Columbia blew up during reentry and I got side tracked and never picked it back up again.
"Let's do Nitrous" I see what you did there. :)
he was a wild man in college i bet 😂
He literally called attention to it in the video.
This is AFTER brain cell loss?!
(Not that that's an actual effect of sane nitrous use, or they wouldn't use it for anesthesia.)
Had me going..no 41.3 not 42.3 lbs. Love the channel keep up the excellent work! Used your sugar rockets in the stem class last year!
Great!
For those curious, scrubbing the sulfur dioxide out of racing nitrous should be as simple as bubbling it through a saturated sodium carbonate solution (long-boiled baking soda). Might require 2-3 passes/chambers, and an activated carbon filter at the end for good measure. Such a set-up could also be used for a DIY re-breather, though as the oxygen depletes there is a risk of passing out and dying without realizing the O2 is low.
I love your countdown “on 3, 3 2 1 0” I think you mean on 4 or even on 0 😂🤣😂
I have seen solid fuel with differing patterns vs a generic hole. If my memory hasn't gone to shite, I remember where a "star" pattern on the combustion interface gave a huge kick at the outset and throttled back, automatically, as the burn progressed. I know that I am tossing another variable into the mix, but I remember the paper saying that it was a "massive improvement".
That would make sense. More surface area to start off but it would tend to burn into a circular shape and taper off as you said.
Finocyl (fins on cylinder) is more popular as its easier to make (much easier to machine a mandrel for) and very closely approximates star grains.
They are used equally in solid and hybrid engines. I've made some finocyls before, they're good but add a lot of work.
This is true in solid rocket motors. In NOX hybrid motors the faster the fuel burns the higher the pressure which reduces the NOX flow thus reducing the pressure...
Burn stability can be a real challenge in hybrid motors. Many amateur hybrids sound like they fart themselves into the air. Different fuel grain geometry can help.
Plenty of 'old school' stuff on the effects of solid booster core geometry in Scientific American 4-5 decades ago.
The geometry and throat ratio to burn-chamber area has a big influence on thrust and burn speed, even tiny changes can make dramatic (catastrophic) results. Some nozzle throats are designed to specifically ablate/degrade as the burn progresses. There are core/compositions that start with a short high-impulse 'chamber' then transition to 'end-burning', or a progressive 'layered' change in composition to achieve the same result.
This is a great channel, I am currently working on the desiccant air conditioner using peltier for the heating and cooling, and a thine baffle with ceramic resonance atomizers to mix the air on regeneration and dehumidifing areas.
I just found you and this channel... I'm closing in on 40 and it feels like the scientific approach to The Anarchist's Cookbook. It's elating, yet ethical. Thank you for this!
One of the best feelings in the world is someone referencing videos that you've already watched and understand everything so clearly because of it
Tech Ingredients: talks about nitrous
Vin Diesel: *INTERESTING*
The Virgin Galactic craft is carbon fiber - fiber glass, burning NO2 & Rubber, so it's a 1970's corvette that goes up! :P
All the information to keep you safe... and if ignored all the information to go horribly wrong! I love this man.
The only channel where we can talk about rochets, dragster cheats and sous vide all in context. Man I wish I had had him a science teacher!
I always wonder where you learned all this stuff to begin with... Thanks for the great video!
Right? How can he knows so many things so deeply in so many fields
By doing (and research to make the doing work.)
The depth of knowledge he has is like an mmo player. This is what happens when you don't have video games, but are instead forced to min-max your speakers, race car, moonshine and catamaran.
This man talks about nos in a way that lets you know hes got a foxbody sitting in the garage that he takes to the drag strip on the weekend and walks all over everyone with. Aka this isnt his first time playing with this stuff
I’m not sure he is the foxbody type... he is wearing a button up shirt AND it’s buttoned!!!
However I am quite interested in his choice of car for a drag race. I see him with a Datsun 510 bracket racer complete with a knob to set the desired time.
LS swapped volvo wagon
"...and 10 seconds is enough for a dragrace - hopefully" - whatever he's running, it might just have a cage and a chute.

This channel always gives me “Shop Envy”.
Very interesting. I did this about 65-years ago. Not having access to graphite, I made my nozzle from steel but machined the convergent and divergent surfaces to a hyperbolic surface using a lathe much like you show here. I ignited it using nichrome wire connected to an auto battery. I rented a 16-mm movie camera to record the launch but I needed slow motion. One frame shows the rocket and the next one shows a hole in the ground with lots of dust. The rocket went out of sight, and we never found it. Then some rocket boys from China Lake visited our city and told us to stop because what I was doing was too dangerous. He didn't have all of his fingers. I stopped.
When you talked about the liquid rocket engine disadvantages, with heat and pressure it reminded me of an real world example of this that I personally experienced in my IB Chem class in high school.
We ended up finishing the chemistry book super early and had a lot of time on our hands. Our teacher ended up just doing fun chemical experiments that we would all just do to essentially fill the time (with him I might add). One day he decided to make an Acetylene Welding torch out of a 20 oz Coke Bottle and Bicycle pump tip punched through the cap. This however wasn't the issue. The performance was rather mediocre.
First issue, the pump tip was split at the end do the flame was spread rather being concentrated. We decided to take a metal file and cut it to a single hole. Second issue, which was my bright idea, was that we needed Oxygen to be produced the chamber as well in order to create a hotter flame. This was a conclusion since the flame wasn't actually cutting through the metal. This is where things went wrong. Biggest issue was we didn't double check out assumptions before doing it or the worst thing in chemistry was DO THE MATH.
So next day rolls around, we had decided to do this and figured out how to produce Acetylene and Oxygen at a 1 to 1 ratio. The only reason I'm here today is luckily we didn't bump up to the 2 liter bottle like we originally planned and made a larger mixture. So we put new tip in drop everything in and we're off to the races. It's cutting and I mean you can tell the pressure in it. The flame is also just hot and starts actually cutting the metal. Right about the time we're all pleased with ourselves our teacher goes to say "Wow, this bottle feels a lot hotter than...." *BAM*.
At this point, all of us have hit the ground, plastic shrapnel is flying everywhere, and when I say our building heard it they all came looking to see what happened. Like there was a school announcement about it to not be alarmed. Everyone cleans them selves up and doesn't say much. The next day we decided to look up what went wrong. I did the actual combustion calculation, some started researching Acetylene with Oxygen and we reconvene about 30 minutes later. Much to our surprise the ratio of Acetylene is 1 to 2.5 times for Oxygen. Acetylene also by it's nature is unstable. On top of that Acetylene gas must never be drawn from its cylinder at pressures above 15 psi because it can spontaneously and explosively disassociate into its components. This is why acetylene regulator gauges display a red warning arc above 15 psi. Which our best guess it we were far beyond that PSI.
All of this combined with the fact that OxyAcetylene is about 10 times more combustible that OxyHydrogen. So glad we didn't do the 2 Liter that day.
worth the read
Here's to increasing your community engagement
Hearing that you read all of your comments, I must say this:
As a somewhat stagnated 22 year old with a history of depression, your videos genuinely inspire me. The prowess of not only application of scientific principle but also the rich understanding necessary to even utilize it as effectively as you do speaks to a lifetime of learning and knowledge, which is something that gives me a lot of hope and quite a bit of vigor! My passion is in chemistry/neurochemistry/pharmacokinetics, but I have a general thirst for knowledge. Seeing you as a successful person not only shows me what my future might look like, but also makes me excited for the journey there!!
Thank you for doing what you do, and don't ever wonder if your work here on UA-cam has had any impact; at the very least, it's strongly impacted me during a time of need!
I feel similarly about his presentations. When I was 22, I hardly had the introspection to recognize my own depression. It sounds like you are on the right track. Keep up the fight, and speedy speed to you.
Goldie Hawn is an actress that often suffered from depression and made a valuable observation.
"The best way to deal with depression is to do something". Inaction or perseverating on the past accomplishes nothing and reinforces the negatives.
Best and most comprehensive explanation - and proper handling - of commonly available racing-use nitrous oxide tanks and basic plumbing. Thank you for investing time to make videos that encourage safety while evaulating and optimzing systems to engineer a high performance result. Long time subscriber, this is one of your finest videos.
"this is a very efficient freezer", then walks away with the door opened 😳
You see how effecient it has to be?
the cold air inside is heavier than the air around so it does not escape from chest freezers as easily as it does from the door freezer - that's by design
I knew it would bug the heck out of some people :D
we're conditioned towards closing any open fridge or freezer as soon as possible. home appliances even beep at you if you're not quick enough

LOL thanks
"So lets do nitrous. Or I should say, lets talk about nitrous." I almost spit out my drink from that deadpan delivery of the rare joke, it was great.
Also, I always love the level of detail in these videos. Going to use nitrous as rocket fuel oxidizer? Here's everything you need to know about bottled nitrous, including how the tanks work, how to mount them to improve their efficiency in car racing, how to fill them (and heres another completely detailed process for just that, including the equipment), why to fill them by weight and not overfill by volume, sizes of tanks, the proper angle and orientation to utilize every drop... and thats literally just getting started. He leaves almost nothing to "common knowledge" or common sense, but I still dont feel talked down to, or treated as ignorant, and that is one of the finest lines to balance in all human interactions.
I sure love your channel- you are a man after my own heart! The first time I made nitroglycerin I was in the third grade.
Mixing nitrous , turbos and piston engines is a good combination
Get ya some 'engine rich combustion' that way.
@@Miata822 Not if you do it right...
One of these days I just want you to do something simple like making a peanut butter sandwich combined with your usual commentary. 45 minutes explaining the chemical bond between the bread and peanut butter.
“Ok so I’m going attach the peanut butter to the bread in 3…2…1…”
This sounds like something I would do...
There's really only 3 primary variables in the making of a good PB&J:
- the structural integrity of the bread
- the viscosity of the J (jam typically has a more homogenous viscosity, and is therefore preferred over jelly)
- applying the PB and the jam on opposing pieces of bread, to be joined only at the point of completion.
This last factor helps immensely with achieving an even spread, and simplifies the assembly process. As well as avoiding any mingling of ingredients in your PB and jam containers. The main advantage though, is that the jam (or jelly) will stick much better to the porous surface of the bread, than it will to peanut butter. In particular since jam and/or jelly is a water based mixture, and peanut butter is an oil based mixture, so jam or jelly tends to slide across peanut butter too easily, which can make spreading it more difficult. So you want to have a peanut butter slice of bread, and a jam (or jelly) slice of bread, which will come together on final assembly. The spreading of the jam on the bare bread also helps to push it into the tiny irregularities in the surface of the bread, to achieve a more secure fitting of the jam material.
The jam (or jelly), has a temperature dependent viscosity. And often there's a small amount of fluid separation over longer term storage. So you'll want to make sure your jam or jelly is chilled to around 5 degrees centigrade to increase it's viscosity. And prior to opening the container, you'll want to shake up the jam or jelly rather vigorously in order to re-mix any fluid separation. Alternatively, you can open the container and carefully pour out any separated liquid, but even then you will want to shake the container after re-closing it.
Now there's a few ways to increase the structural integrity of the bread. Obviously, you can get a somewhat more dense bread, which will resist tearing to a greater degree. Or, on a somewhat lower budget, you can make cheap bread have greater structural integrity by lightly toasting it, or even laying it out in open air for about an hour before using it to make your sandwich, so that it slightly hardens.
For a more filling sandwich with a generally better texture and flavor though, a slightly more costly, more dense bread is actually preferable. Multi-grain breads also offer increased structural integrity, as well as a lower glycemic index, which is generally more healthy, not to mention having a somewhat more varied nutrient content. Here in the lab today we have some Dave's Bread, more specifically their 21 grain "killer" bread. This is a very dense bread, with a large amount of multi-grain and texture, and the fibrous material which makes up the multi grain tends to increase it's structural integrity, so we won't need to do any toasting or spend any time forcing the bread to go stale to increase it's structural integrity. And while this particular bread is very flavorful, it remains in the general flavor range of a white bread, so you don't have to worry about flavor contamination.
Spreading is highly dependent on the shape of the applicator. For the peanut butter, we're going to use a typical butter knife, but we'll be using the straight flat spine of the knife, rather than the rounded edge, to achieve a more even dispersion. However, once that even dispersion is achieved, you'll want to push the spread slightly to the periphery, in order to provide a more firm support for the less structurally stable jam. Also it can be useful to deliberately roughen the surface slightly to create more surface area for the jam to bond to when final assembly occurs.
Now there's a large debate in the industry about whether to include or exclude the crust in a PB&J sandwich. Generally, the crust adds a great deal of structural integrity to the sandwich, as well as providing a more rigid barrier to help eliminate leakage of the Jam. But some breads have a crust which tastes mostly like burned glucose, and that can adversely effect the flavor of the resulting sandwich. The best solution we have found here in the lab, is to simply get a bread which has a better tasting crust, allowing us to benefit from the structural integrity of the crust-wall around the periphery of the sandwich, while avoiding the potential flavor pitfalls which some bread crusts entail. If you were going to use a cheap bread and remove the crust, you'd want to do that as a final step after sandwich assembly, so that the crust could help maintain bread structural integrity during the spreading phase. And the applied force of cutting off the crust would press the more fluid contents of the sandwich inward, rather than outward, and avoid leakage of the contents. But we're using a bread with a higher quality crust, so we won't need to worry about removing it in this example...

You're always so in-depth. Most UA-camrs would be too afraid to post a 40 min video.
The more amazing thing is that there’s 40 minutes about rocket science and there’s 0 mistakes or bad information. This dude just knows all this.
All of these supplies and equipment are also tremendously expensive, and he just has it. This whole channel baffles me for that reason.
Nonsense
SpaceShipTwo that just took Richard Branson to space uses a nitrous hybrid rocket motor. So, they've been to space.
Edit: This was probably filmed before that flight happened, so I don't fault him for not mentioning it. Just wanted that out there.
It doesn't go to space as it doesn't cross the karmen line
@@henryefry The Karman line (the one you are talking about) doesn't measure where space starts.
The Karman line you are talking about (it changes by jurisdiction, define your terms) is the Federation Aeronauique International's (FAI) regulatory convenience altitude established in the 60s. It only exists to determine agency jurisdiction.
Karman himself placed the lower boundary around 80 km.
According to NASA space is 50 miles up, give or take a bunch of variables.
If you say Spaceship Two didn't go to space then neither did the X-15, and you're going to have to demand they give their astronaut wings back.
You're not wrong, because you're not even wrong. Your argument would have to improve just to get to wrong.
That's what happens when you carry Jeff Bezos's salty tear water.
@@henryefry Well, SpaceShipOne actually DID cross the Karman line to win the Ansari X-prize using the same NOS/HTPB hybrid engine design, so the point still stands. Subsequent flights may not have reached the Karman line, but they do cross the 50 mi mark that NASA and USAF use to mark space and award astronaut wings.
@@Timestamp_Guy only NASA uses 50 miles, so I don't count that as space. You gotta get to 100km for it to count.
Who cares what NASA says no one else uses 50 miles. Everyone except NASA uses 100km. Not officially in space if you don't get into internationally recognized space.

“Okay, let’s do nitrous.” Thinks ‘wait, some people actually imbibe this stuff. Poor choice of words.’ “I mean, let’s talk about nitrous.”
Are you worried you’re going to relapse or something?
It’s not addictive. LOL
Also, the high is kinda lame.
I'd be curious to know why for each nozzle test there's a visible drop in pressure/flow right after the first blast. Thank you very much as always for your insightful videos!
Possibly some amount of ice crystal formation at the nozzle chokes the flow a bit?
@@alexponting3325 I was wondering if it was about temperature drop. Joule-Thomson? But then why the timings of the choke doesn't seem to change between the first nozzle (with probably the smallest diameter) and the others?
Made me wonder, too. Probably the valve in the solenoid is bouncing.
You know, it's quite remarkable how many relevant angles you cover, so comprehensively, in your videos.

I can't decide if its funny or sad that as soon as something can be used for people to get high, it gets regulated, but once it's been fouled enough to stop that, it's a non-issue.
In EU they also ban anything that can be used by "terrorists" - as if citizens are terrorists by default :(( ... applies to many basic chemicals including nitrates and oxidizers like conc. hydrogen peroxide, chlorates, perchlorates etc. etc.
It is sad because their regulations kill hobbyists that may become great engineers later... making people generally less interested in natural sciences or just having any real fun.
@@LiborTinka Yeah. As regulations expand, the ability of everyday people to tinker and explore becomes more and more limited. A vague sense of dread seems to be all it takes for something to become restricted beyond the reach of ordinary people.
What is your background?! Like seriously how does one guy have such a depth of knowledge in such a wide range of fields?! You’re inspiring, my man!
We'll get into that and a lot of other topics on our second channel which is in the works.
This is something I always found fascinating. I'm very glad that you are doing instructional videos. Thank you.
I cant be the only one he just taught the pronunciation of Sous Vide...
Sue vee'd ;-) French is a very strange language when it comes to writing things down.

The highest quality scientific information available on the internet. It's like being an intern at NASA with a really good mentor.
Awesome to see pyrotechnics and rocketry being demonstrated in a safe way.
When I was a military pilot, our short range missiles were solid fuel. It seemed a little far fetched, but one of the precautions for handling them would be to take off any digital watches. Guys complained it made them tense if someone were in the cockpit and they were hearing relays clicking. They made us help them at least once, so what they were doing at the time remained remained part of thoughts while in the cockpit. Another that is easier to understand was that if one is subject to a fall that it could not be used because of the possibility of the propellant inside incurring damage thereby effectively adding porting/surface area which could greatly increase the internal pressure. Concerning the USS Forestall incident when a Zuni (AIM-9 variant, solid fuel motor) hit John McCain's plane and triggered explosions and fires that killed 137, most tended to not accept the pilot's account when he said he was certain he had not triggered the missile by accident during his checks. There was a lot of talk about possible scenarios of how it would be easy for that to mistakenly happen. They had approved abbreviated procedures (there was a war going on) which were afterward rescinded. However, there were subsequent unanticipated launches and non-launches, and combined with pre-USS Forestall incidents, came together to cast doubt about their foregone conclusions that these incidents could all be attributed to human error. This revealed there were non-human issues involved. These play into what you said about solid fuel rockets.
The USS Forestall incident isn't all that different than WW II where they replaced a lot of sub commanders with new guys because they said the sub commanders were too cautious and they simply missed. Later they would learn that the Mk 14 had 4 major areas of failure, and even had a 70% failure rate even with direct broadsides. However, it is more logical that they fired their not only most experienced commanders, but also their best commanders, and likely would have been more effective with fewer losses, because they had the moxie to calculate an accurate risk vs. benefit based on their experience with the Mk 14. If you were a member of Seal Team 6, and 7 out of 10 time you pulled the trigger nothing happened, you would soon learn the best way to stay alive long enough to be effective would be as a sniper. They wouldn't investigate the torpedoes until after decoding Japanese intercepts which reported what their sub commanders had been telling them. Lockwood was on the wrong side of the torpedo problem in the beginning, and it appears to me that linking cause and effect to replacing commanders is more an effort to sanitize a part of his otherwise stellar legacy and to the benefit of the Navy's and others.
Interesting, thanks!
Love the content - thank you. As a sound guy, I would recommend using an over the ear microphone instead of the lavaliere so that you don't get the level surges when you move your head around. You could mitigate it a little with a comp or limiter, but it sounds like when you move your head down you get a little distortion.
I did a research project in undergrad on hybrids. I never got approval to actually get the nitrous (#dumb), but did some cool machining for the actual engine. I used brass as well instead of stainless. My idea was using 3D printed matrixes to stabilize the paraffin during the burn by having it exposed to the flame front in sequential concentric rings, separated by slower burning ABS. The 3D printed structure also enabled the kind of helical ports required for high surface area/low volume (a fix for the regression rate issue). The project was about combining different technologies to get the highest impulse (volumetrically) motor ever made. in theory such a motor could be used in storable applications like mars sample return, as nitric acid can be stabilized for deep space storage. cool stuff, I might go back to school to finish this project, or do it in my garage if I get time (and a garage lol) . I enjoy your channel as always.
I have been eagerly looking forward to this day since you first announced your rocketry program.
Thank you.
Really wonderful presentation here.. I'm SO happy I found (was directed towards) your channel!! Thank you for sharing your years of knowledge with us. I've been a scientist at heart my entire life - a self taught engineer in practice with a love of all things mysterious.
Best episode ever. EVER! There is much to appreciate, but the moment(s) I enjoyed most was the 21st century rocket science explanation about the rocket nozzles in front of the rough sawed shed wall, with the flickering shadows from the sun through trees. Exquisitely presented!
I don't understand why this channel doesn't have a billion subscribers
engagement, engagement, engagement. happy, youtube? no please give this man more of your ill-gotten money, please? Krasnow and this man are what everyone alive should be watching more of and I trust youtube is going to do that. You also remind me why having kids is a smart idea. Best Internet Scout Leader ever!
Thank you so much for the fine level of detail in all of your explanations. This is a channel I learn so much from! Keep doing what you do!
These are great motors. My buddy and I built some high impulse m-motors, shot a rocket up 20,000 ft down in washington state. It hit 811 mph at 100ft off my trailer. Was awesome. We used PVC as the fuel grain
You are an excellent an engaging teacher, and I'm sure your students tell you as much!
Saw the 4th video first, now I'm back to learn how you got there. Great stuff!
Don't forget get about Rocket Lab's Rutherford engine. It's an electric pump feed liquid fueled engine. Or pressure feed engines like the Kestrel engine used on the falcon 1, a very simple engine compared to the full flow Raptor engine.
Draco and SuperDraco in Dragon 2 capsule is pressure feed too.
Phenomenal series, can't wait to see the next video!
Tomorrow!
Amazing level of detail ! University classroom quality. Excellent video! Thank you.
While I don't have the technical skills to implement any of this knowledge, it's incredibly interesting to learn about all of this. Thanks for the amazing education.
Great video as always, this comment is actually for the (less) sung heroes/ingredients of your show, your son(s) I'm assuming who do all the editing and camera work. I can't explain it, but they're lifesavers for the fine details and direction they take. Each episode it's more refined and I find compared to earlier videos I absorb the message more and more. Hats off to the tech guys at tech ingredients. I'm sure they get rewarded with all the fun explosive bits hah.
You contentiously produce quality entertaining videos, both with high production value and in depth explanation. I also love how you explain the "why it works" and the "how it works" while simultaneously showing exactly how exciting the given demonstration really is. Thank you for providing "mind candy" to the world! You rock F'n rock!
Excited for the nozzle fab instructions!
I love it. Found you when you built your own room cooling stuff. Now we're here watching you building rockets. And imagining how it would be to actually build one on your own. Guess my neighbors are very happy that I'm only dreaming about it instead of blowing everything up.
You guessed right. We have had a LOT of local attention!
