So this is what it looks like when you know what you’re doing

[@AlexW-]

But don't change the way you do your videos we like your .... mhmmm wild production style

[@Cloudsinmidair]

Hey, I wasn't expecting to see you here 😂

[@JohnSims-vl4wg]

HX-752 is dangerous bla bla, but tomatoes are disgusting anyway 😂

[@ultratorrent]

If you weren't showing us what not to do, Integza, we wouldn't even be able to appreciate Joe and his work at this point.

[@gavinblaedow9255]

lol I’ve been watching you both for years and you both have interesting and very different ways of approaching science 😂

BABE WAKE UP NEW BEPIS SPACE VIDEO DROPPED

[@E-dart]

Bepis is crazy

[@NeonNijahn]

I'm up I'm up!

[@eannamcnamara9338]

That's for waking me pookie

[@localsms]

It went from talking to the wife about fun rockets into fun facts about HX 752 and reproductive systems.

[@WSpace7]

“Bepis Space” 💀

[@Admeen3581]

To my FBI agent: I’m watching this for entertainment purposes only.

[@NeonNijahn]

Move along. Nothing to see here.

[@zchris13]

FBI doesn't care, the ones who might care are the BATFE

[@RustyMTB]

It’s ok FBI agents view my LinkedIn every so often. To my fbi agent this is just for funzies

[@william5931]

Just wondering why you need this knowledge. --Your FBI agent

[@NeonNijahn]

@william5931 I don't. I just watch videos about random shit all day. I won't remember this video an hour from now. I'm a sad lonely soul.

[@shoitah]

The most underrated part of all BPS space is the videography. Stunning, professional work. Great job, Joey!

[@Brian-bk9qv]

Agreed.

[@trainedloser]

Absolutely, these are always top notch. I forget i'm not watching a big budget produced documentary.

[@fearlessgaming976]

He is musician and you can see his video music stands out from other channels music because he makes all of them and i think it is most underlooked aspect as people think he copy paste music of others .in reality it takes work forr 2 min music

[@ConnorisseurYT]

yet another Joe Barnard video of all time. This one brutally shattered my kneecaps, thanks Joe 👍

[@BPSspace]

You are welcome!

[@leifhietala8074]

"Not a fun tangent," and yet PRETTY DARNED IMPORTANT so thanks for that, Joe. Good safety tip.

[@mr-huggy]

Reliant Robin is also the car that Top Gear used as a space shuttle in their launching of a space shuttle.

[@mr-huggy]

By the way don't ever show it on KZbin it's an instant takedown.

[@Thefrontdoorscientist]

Joe should send a reliant robin to space. Using reliant robin

[@kender242]

[@BPSspace]

@@mr-huggy I KNEW IT - This is so validating lmao. I thought of mentioning it and just showing a photo but I figured I'd better play it safe and just reference the car instead of the Top Gear episode for that very reason

[@adaama4460]

It's also the car that Mr Bean continuously has altercations with in his Mini!

[@fullflowaerospace]

“woah that’s such a good chemical, it really makes life so much easier.. what could be bad about it?” “OH WAIT NVM”

What could go wrong?

[@fosstera]

12:21 Dude you got me so good i was like NO STOP then burst out laughing when you explained

[@whyevenotter1578]

Out of every channel I am subscribed to, I am by far the most excited when I see a new upload from this one. Amazing videos

[@jpburned2414]

I grew up with harry, used to be best friends. Haven't spoken to him since middle school, but I've followed his rocket engine tests ever since and I think it's so cool that you're using his formula!!

[@leomonk974]

7:31 this tangent is probably the most telling about your character. It’s an honorable one that in my opinion deserves way more recognition.

[@PatrickKQ4HBD]

6:45 ff, Thanks for including this part. Seriously. I don't think I've ever seen another presenter take on the issue so directly and yet politely. YOU SIR, ARE A GENTLEMAN AND A SCHOLAR!

[@robinvanderpal372]

absolutely, that was great.

[@PatrickWilson47]

Awesome video and I enjoyed the tangent on the MSDS like I say at work “Better to be Safe Now Then Sorry Later”

[@JonahGreve-bn6jc]

A couple of months ago I found your channel from the time you talked with Tom Stanton in his video. I was immediately drawn in. In the next four days binged your entire KZbin channel. I got to the end and subscribed. You are an amazingly gifted person. I can't ever imagine knowing all the things that you do let alone teaching me them myself. I thank you for persevering through your scrubs and failures to continue to bring us all your incredible and inspirational work. I ask God to bless you with many launches in the future. May your skies be blue and your winds be low.

[@wardyosh]

As a researcher with a PhD in organinc chemisty I have had the conversation about chemical hazardous and risks many times . Through someof my hobbies hazardous chemicals have come up several times and trying to convince people that the dangers are real, and could have life long, debilitateing effects is shockingly difficult. Your explination of the hazardous of the chemicals your using was exelent, precise and struck the right tone. I cant stress enough how dificult that is to do, you rely are an exelent comunicator and I will definitly use this as an example the next time I have to explain similar risks.

[@timcovey7280]

I don't recognize said authority, As a garbage man I see hazardous organic chemistry everyday and know how to spell it.. What exactly do you research with spelling like this, We are doomed..

[@lonewolftech]

😂😂😂😂😂😂😂😂😂😂 much fail

[@jimurrata6785]

Really good brief overview of APCP. Id like to see you delve deeper into the more "flamboyant" additives like titainium flake, strontium, barium and the other colorful pyrotechnic nitrates and salts These might not have a place in a space shot where any properties that compromise ultimate ISP probably arent welcome. Lecithin is an emulaifier in the food context. It helps keep things from separating.

[@AsmodeusInflect]

This is spectacularly well presented. You covered a complex topic in an approachable way - I wasn't lost at any point, and you hit the safety aspects effectively and concisely, and highlighted exactly why they're an important consideration which I love to see.

[@DrZeus108]

Oh wow I was not expecting this level of depth. I was completely engaged and I am sad it’s over. I am excited for the next one and hope it’s even longer with more great info. Thank you

[@Daan_Music_]

This is one of the best long term series in all of youtube. I cant wait to see where it leads and the amazing journey ahead. Keep it up!!! You're doing awesome!

[@benjaminnevins5211]

These videos have been getting better and better!

[@backpackerx]

We don't deserve the level of detail you put into these. The sheer effort that went into filming and editing that first two minute overview was amazing.

[@genxtech5584]

Your video series has come a long way Joe. Quality work here, you should be proud!! You may not realize it yet but you will inspire children today with science that will have profound impacts on our world in the future.

[@mr.weirdo5756]

It`s such a joy to see how far you have come. From shooting your first test rockets to this, always blows my mind.

[@universalrockets]

You have no idea the happiness of seeing a new BPS Video

[@justinrobinson9524]

Thanks Joe for the great video as always

[@aculleon2901]

Awsome stuff man. Beautiful shots.

[@CoronaFighter_]

my face when joe picked up the "ammonium perchlorate" and, without any context, just EATS IT-

[@waylontmccann]

Joe man, I love that naming convention. Great work!

[@TeaRex]

Taking a break from studying for my Thermal Rocket Propulsion exam after getting wrecked on a question about a Solid rocket motor and what do I see in my recommend. More solid rocket motors. My life is a sick joke haha Edit: in my textbook it's De Vielle's equation as well, guess that needs updating

[@johnholleran]

Great video, Joe- can't wait to see the rest of this series! Stay safe out there

[@bennyfactor]

Always happy to see a new video for you, most of all because you do such a great job of explaining literal rocket science, but also because it means you didn't get a a visit from Raytheon or General Dynamics or whatever with one of those gigantic checks and some balloons with the caveat you don't get to make videos any more.

[@macios502]

I love that when You read the script You are moving Your head so it looks more energic and a good way to cover the eye movement. Loved the video

[@billgaytes6845]

New to this channel. Amazed at what you are doing. While other KZbin's talk about rocket science you are actually doing it.

[@thatstarman42]

YOU TAKE THE HTPB, IDP, ALUMINUM AND MIX AND ADD THE PER-CHLOR-ATES! YUM! 🎶

[@110Genesis]

I've been following your progress for a few years now. It's simply incredible and inspiring, honestly. Keep it up!

[@leggo0]

Joe you are so amazing at explaining and breaking down complex concepts.Always look forward to these videos!

[@thom7440]

Great video, Joe! Looking forward to future vids where you explain more of the technical stuff

[@kreelaban3420]

Lecithin is actually an emulsifier. There is lots of it in chocolate. the more lecithin, the smoother and creamier it is. It is great for keeping fat soluble in your blood so you don't have a heart attack from drinking real perclorate mixtures accidentally !

[@hugacreeper69110]

It’s been really cool seeing the scale of your projects evolve over the years nice work!

[@fabotond]

Iam having an Algebra exam in Feburary, and it makes me question my life choices... but watching videos like yours encorage me to learn that shit. You were one of my main inspirations to go and study engineering.

[@lonewolftech]

😂😂😂 algebra isn’t even hard it’s the trig, calculus, and other shit that’ll fuck you up in engineering. Just remember with algebra most of the formulas are given already you just have to learn to plug in data.

[@rrmackay]

years ago as an amateur rocketry member we mixed solid propellant using NH4MnO4 and powdered aluminum with a 5 minute epoxy as a binding agent poured into 2" diameter by 24" length solid rockets. It was wild because the epoxy would get very hot during the curing process. Scary stuff.

[@dougyoud5944]

Nice work Joe! Looking forward to seeing the data on that motor my buddies found out at Black Rock desert last year :) hope it’s made its way back to you by now.

[@lpngcf266]

I remember when you weren't feeling so good and you had to spot for a while. Glad this is where you are today!

[@user-om5gt7ik4l]

Congrats, after more than 5 years you are my first youtube comment. Thanks for finally describing the full details of propellant design, interesting stuff. There's no protecting idiots from themselves anyway, if they are determined enough. Best you can do is explain why its dangerous instead of just giving them an instruction manual. Which you did. As a former research chemist, I'd have to disagree about avoiding toxic chemicals on principle (I've used much, much worse), but I guess I wouldn't want those in my garage. Nice channel. Good luck with the spaceshot!

[@Streetcarsaturdayshuntsville]

Prolly my fav tech video Love the openness of knowledge Can’t wait for more vids on this motor!!

[@ltpinecone]

Another excellent video! Humor, science, and outstanding videography! I also really appreciate your emphasis on safety. Great stuff!

[@Arthur-rh9tf]

Holy crap, very impressive. Been a pleasure following you on this journey. Awesome work dude.

[@MarcusHouse]

Super interesting Joe. Thanks for making this.

[@the-witness8811]

You could get rid of those bubbles in the mixture using a sufficiently small concrete vibrator. This is how we ensure stable solid foundations with concrete. Just know it'll cause some of the more watery substance to rise to the top, since it is lighter. I also don't recommend using this method with any fuels that are sensitive to impact or jostling. Just an idea. Thanks for the videos man!

[@CDRaff]

It's fun how so many propellant mixture names are full of puns and easter eggs that reference each other.

[@98karlh]

as always, just super nice quality content. looking forward to next one

[@lit_for_20]

you make all of this sound so easy to understand. i wish some of my teachers would've been like this

[@tristanbergh8655]

Hey Joe, rocket scientist here, wish I’d had this channel available when i was studying. learn by doing - yes! The studies only touch on a lot of stuff which you’ve absolutely dived into and really got skilled in - i love your videos!

[@fabian1150]

Thanks for all your effort! Never thought that I get so interested in this topic but here I am and I can't wait for the next video :)

[@user-gf8qs1dg3w]

I just love seeing the one upload per blue moon come from this channel. Hopefully some day you're able to reach said blue moon with these amazing rockets!

[@loganki5zyw]

Been here 4 years since I discovered u as a little kid. Still following with interest... Can't wait to see the space shot

[@-r-495]

thank you for the appropriate warning concerning the risk potential of the educts and thinking about the product and cleaning and disposal. intriguing!

[@-r-495]

I agree with ball milling for the AN. personally I‘ve worked with gas mills and far finer grain size range.

[@moldovianfieldmarshal6313]

I will need this in the near future, thank you.

[@curtiscapdeville6011]

You mention the use of MDI as the curing agent for solid propellants. Now I work at the solid rocket manufacturing plants in Utah where we all sorts of different propellants. And of all the formulations I know of, none of them use MDI as a curing agent. Also the curing agent we always went to in college was D.E.R 331 or DDI curing agent. Those are much more readily available and are not as toxic as MDI.

[@hvip4]

Man there are a lot of science, experimentation, engineering KZbinrs I watch. You're among those top of the line straight up madman. There are the popular science guys who are just using cool tools and materials like vacuum chambers, ooblack, ferofluids, liquid nitrogen to make experiments done a 1000 times before. Then there are awesome builders, creating jets, airplanes, plasma, laser, chemistry, high voltage experiments and many/much more. Very extremely cool projects, but mostly for themselves and KZbin, without a clear goal. And above that there are the madmen. Off the top of my head I can think of "Thought emporium" and yourself. Doing stuff that requires some brutal scientific research and dedication and a clear goal in mind. I am not an expert I have just been interested in this kind of content since the beginning of KZbin. I really appreciate what y'all are doing ❤

[@fdelacou]

Brilliant was an excellent choice of sponsor for that video! On the other hand, AG1 could have been one since it was also about chemicals that could neutered you! /s

[@IronAnt2008]

At school i was looking for new videos of you and now when I’m going to sleep you post.

[@JustGoAndFly]

Very good video. Excellent pace, no irritating Adderall narration, super interesting stuff. What all KZbin videos should be!

[@tec4303]

THANK YOU for talking about safety!!!

[@AllThingsSpace3]

nice work BPS

[@eannamcnamara9338]

It's awsome seeing how far you've come, from testing thrust vectoring with standard hobby motors to literally msking your own fuel for a space shot! Also eating the sugar really got me! Im telling you, BPS and Copenhagen suborbitals should team up, place your space shot on top of their spica instead of the capsule for a bargain bin vanguard rocket if you will lol

[@FinnBuildsThings]

Wish I had this skill and brain power, I’m just now using fins with mobility but even that barely works. Keep this awesome stuff up!!!!!!

[@codemonkey2k5]

Super interesting. Thank you!

[@fledglingrockets]

Waking up to a new BPS video is the best feeling! (I only now realized how similar our logos are)

[@timewing5501]

For those of you who don't know, 0:21 is a Pegasus rocket launch - an insane rocket that launches satellites into orbit by dropping a solid fuel booster from a plane. I used to be a flight controller for CYGNSS, a constellation of satellites launched on one of these boosters (and probably the one in the clip). Really cool to see it in the wild!

[@ryomensukuna0616]

Last semester I studied this things as rocket propulsion system had 5 units solid rocket pro, liquid rocket , hybrid then electrical propulsion ...damm it was ...main highlight was learning regression rate in hybrid and liquid rocket specifications...thou we couldn't study entirely but got an raw idea of rocket propulsion system as an aerospace engineering student...now after seeing this video I can literally remember wht I studied and can understand nowww more easier ❤... amazing mate....if in case you conduct some free online internship( mainly I am from India ) please notify us because you are an excellent teacher and scientists

[@davidlabedz2046]

Thank you for such an informative and fascinating video. On to the 100km flight.

[@aravjain]

Yooo!!! Great vid, Joe!!

[@nathanguyon7620]

I love this series. Side note, always wondered what kind of difference if any using regular aluminum vs. ball milling your own and mixing the propellent under an inert atmosphere. The oxide layer is super thin, but freaking resilient stuff. Dunno, just popped into my head after years of not thinking about it thanks to this vid.

[@blakeparker8282]

Love the videos I love rockets and the science behind how they work big or small rockets

[@Djbz91]

Great bit on toxic chemicals really informative 👍

[@Lampe2020]

12:16 Wow, my heart stopped there for a second, until the thought that it might only be sugar came through my mind. And then you said it and I calmed down again **phew** XD

[@B_r_u_c_e]

Excellent. Thank you.

[@xxxdiresaintxxx]

00:01 You start any video like you did with this one and the very first words out of your mouth had better be... "Space .. The final Frontier" Or something equivalently fantastic! Love you Joe!

[@RoseHayes-321]

Great video. Thank you so much for the inclusive language when discussing mutagens.

[@oasntet]

Lecithin is also an emulsifier, useful for getting fats to stay suspended in water. It's commonly found in nut milks to prevent separation, as nut extracts don't have whatever cow's milk has to keep the fat particles in suspension. It's also a pretty handy additive if you want to add something like peanut butter to a smoothie, or want to make a lower-fat ice cream at home without risking ice crystals growing everywhere.

[@Chad-Giga.]

Or want to make potent weed edibles

[@joshdaniel8609]

Those zoomed in shots of the suppressant, aluminum, and other motor ingredients make them look strangely appetizing haha. Anyways, great work Joe!
