The beeping seems to have really triggered off a lot of people here ;-)
While I didn't exactly enjoy it, I was able to tolerate it without too much hassle. Perhaps a video on the science of psycho-acoustics would be a good spin-off from this. There isn't a lot of easy to understand information on the subject readily available.
Agreed.
Explosions and rocket fuel, but the beeping...!
There has to be a psychological component because people almost universally like loud fireworks.
@@TechIngredients It might have something with the learned response in many to look around for a reversing vehicle? Would it be possible to alter the frequency of the beeps to a non-normal range to test this?
@@TechIngredients the beeping obviously didnt help at all for safety as you are accustomed to it and tuned it out. otherwise you would turn it off the second you could standing so close to a piercing noise like that. at that point it stops being a safety thing and it actually becomes a safety problem as you are programming yourself to ignore it.
@@SupremeRuleroftheWorld What you say is true, but often times, safety devices are more for the people not operating the equipment than the ones who are. I'm sure a commercial truck driver doesn't hear the reverse beeper anymore either, but they probably aren't the ones that need a reminder that they are in reverse. I think this falls into that category.
@@TechIngredients I think if you changed the duty cycle and the frequency (edit: the on-off period, not the tone) of the beep it could be made to be tolerable.
Personally i didn't find it irritating only mildly distracting.
Your choice of background music while showing the slow motion portions cracked me up! 😂😂😂
I have zero interest in model rocketry but you make it interesting. I look forward to your presentations and I recommend your channel to those I know that have a functional brain 😳
“Ignition” by John Clark is such a great book.
I think chlorine trifluoride is off the table.
Bought and read it on NileRed's recommendation. It's 10/10.
@@michaelmoorrees3585 thats the one the burns through concrete?
@@michaelmoorrees3585 off the table, through the table, into the foundation...
Nitrified ammonia FTW (Hydrazine)
You are providing some of the best educational videos on TH-cam. I am still waiting for the rest of the magnetic engine project. Thank you.
Thank you for your dedication to being wholesome
i think in one of your magnets videos about 2 years you talked about building a gauss rifle if i'm not mistaking. Did that ever happen? love the contend, keep it up
6:25 always test wind direction before setting up where the ignition table goes :)
I like 3:50 better, haha
Kind of like, "Don't Piss Into The Wind".......
This is by far the best channel there is on YT. Not every topic is interesting in it self to me but since it is so thoughtful done and a lot of physic information there are still always something that is satisfying.
Well done!
I started to play with rockets 50+ years ago. I found tubes that came in lampshade shipping boxes that rocket engines fit perfectly. I glued find on that I made from old playing cards. My problem was, they went so high that I usually lost them. It was great fun for almost no money
I worked at K-mart. We sold the engines in the toy department where I was a manager. I had to try them out
Beautiful. You deserve so many more subscribers and exposure. Your content is top-notch quality. The information, the demonstrations, the editing, etc; it's all done so well.
The final slow motion clip with your cup of grain mixture was absolutely amazing!! Excellent work boys and girls!
I have to say that your videos are really one of a kind. This is just refreshing to say the least. You brought back fond memories of when I was real young 14 making my engines using sugar as the main ingredient. Using monel thin wire with heat shrink tubing halfway up the filament from one end. The tip was just match heads and ground gunpowder. Worked perfectly with no miss fires. Good day too.
I would love to see you eventually venture into liquid or hybrid rockets
Soyuz style.
He had a bottle of nitrous oxide setup when speaking on hybrids in an earlier video I'm sure he will get to it soon. I certainly hope so at least!
You watch too much cody
@@niccosaur7778 lmao true probably I have started to design and build my own liquid rocket engine with inspiration from him and a few others
Just love this channel. Keep on the good work creating such a content.
Excited to see you're tackling APCP next! I had a ton of fun making APCP engines in college and am looking forward to seeing what formula you used and how you went about constructing them. We had Lockheed witness one of our tests and actually had an engine detonate on us - little more exciting of a test than we had planned on! Hopefully all your tests go well and are conducted safely. Thanks for all the fun videos!
My favorite part about this video, is you put so much effort into safety equipment Building Safety Equipment purchasing safety equipment having a procedure and then you stand downwind.
Great looking shots! But I couldn't hear a thing because I had to turn the volume WAY down due to the incessant beeping. Whenever I want to use a power tool in my videos, I drop the volume 12 - 15 dB in the editing software. It just a much better viewing experience.
I just LOVE your content! Hell, just watching your videos makes my fingers itch to set up my own shop to start experimenting :D
Those starters and fuels pack a helluva punch, I'm impressed. Lovely stuff.
I was not expecting the 2nd set of igniters to pop with such force! Love the videos!!
Great video! The slo-mo works great too.
As someone who has always been interested in rockets, this series has been great. The only thing I don't like is that BEEPING!!!! Please disable it, lower the volume or filter it out in post production.
Yeah, he should definitely spend more of his time and money to conform his video to suit your whims. I like the beeping. So what now
Waaaaa
5:08 looks like you need a blast shield. 😆
Don't worry, I think the incessant beeping produces a forcefield to keep him safe :)
@@RubixB0y lol
Awesome stuff guys! Love this rocket stuff. Can't wait to see the advanced fuel stuff. Exciting
Exciting. Really looking forward to your videos. Especially your thermal interface material videos that you tease several videos ago.
This is amazing! Love all your videos!
Thank you for the video, this channel should have a lot more subscribers!
Been here since the laser days. I still love to watch and learn something new in every video! Great job! Really, well done Gents!!
Thanks!
Such a great series...cheers.
You know you hit the sweet spot of your flash powder mix, when it goes "thump", out in the open !
I'm of an age where I grew up on "Watch Mr. Wizard" and "Ask Mr. Wizard" . It was one of the things that led me into a successful career in STEM fields. Watching you brings back the same excitement and wonder. You're Mr. Wizard for grown-ups! THANK YOU!
Thanks!
You have to be a "grown-up" to watch this?
@@dalecomer5951 No, what I meant was that our host is like Mr. Wizard for grown ups. Mr. Wizard would do harmless experiments suitable for children. Our host here does experiments and projects suitable for adults. Although I wish that he had been around when I was a kid, I would have learned a lot without even doing the experiments!
Verry motivating ! Great content !
I love that you have an and-on as parts of the ignition system
The last one put the biggest smile on my face.
Great content! I'm a big fan of the scientific approach you've got, how you plan out experiments, your flexibility to changes and opportunities and the honest conclusions! Btw, maybe use the LRAD system for the beeping? ;-) Oh, And I would suggest some kind of blast screen. You never know when something explodes more powerful than expected and hurts anyone. We don't want to lose another awesome youtuber
Those HTBE engines certainly seem to burn with great enthusiasm. 😃 Thanks for posting.
Who else hits the Like button as soon as the video starts because they know it's going to be great!
❤️ your videos are so educational and entertaining ❤️ Than you
As always very interesting content. I hope this all leads to the actual launching of rockets.
I have loved all your videos,
Like a boss...standing there next to a pillar of awsome fire without even cracking a smile...
Quality video again.
Thanks.👍👍👍
Love your work!
Hi, i'm absolutely amazed by the host. Stunning knowledge and ability to describe principles of physics in those daily use items.
I totally loved the desiccant based air conditioner project, and i have something similar as an idea:
There are many coal/wood boiler heaters models. Maybe you could explain some principles about heating with solid fuel (pyrolisis), fireing up the boiler (igniting the coal from top of the stack versus igniting from bottom). I think that could be an interesting topic for people who are looking for ecologic and smokeless way of heating their homes.
Great channel!
Excellent video.
We used to mix napthalene from old school moth balls, and magnesium dust "barrowed" from material science class... I think that was a fireworks recipe, amazingly powerful.
awesome 😎 videos guys always love to see when you out new content.
I could watch these being ignited all day!
You must have had so much fun.
I am a huge fan and I love everything you do on your channel, that said I am not a fan of the new intro music.
The outro music is still good.
I think it’s because I associated the old intro with so many cool videos I would get excited as it was playing in a new video.
I guess it may grow on me but I don’t think the whistling style really fits.
Sorry guys as I say I love the channel I tell everyone hands down it’s the best channel on TH-cam and promote wherever I can so please know this criticism comes from a good place.
Great shots!
Brilliant, you are brilliant. Thank you
You are just awesome man ! Greetings from Poland :)
Thanks, welcome!
Thank you so much for your efforts in popularisation science
Thanks!
Very good investment the camera!
This is great stuff. I hope as this series progresses you'll also get into some of the government requirements for rocketry. For example regulations on rocketry and fuel purchase/storage, etc.
Thanks, I will.
Looking forward to the full video :)
You managed to get some professional looking footage. Now I want to use sections of this for a moving desktop
Great! A little scary being downwind.
Good stuff. Thank you.
Another great video - even with the beeping! :) I can well imagine the thrust available if those burns were constricted as engines - lot of energy.
I love your self confidence in those engines by standing so close when testing. They can and do sometimes CATO.
Remember, they aren't engines. There are no nozzles and nothing to create an increase in pressure. Once the nozzles are added then the situation becomes completely different.
Great job.
Thanks!
I can not wait for the upcoming video, showing the new higher power mixtures.
Love your work!! This video somewhat reminds me of the Slow Mo Guys, they do some incredible work as well! 😌😁
I wonder if it has anything to do with the high speed camera work?
@@thetruthexperiment it does 👍🏽
Not sure what you guys changed, but the image quality of your videos is fantastic! Great stuff! Looking forward to more
Every post from your channel is worth watching. This is the kind of sh*t I come to youtube for. If the company ever gives you guys trouble vis a vis monetization, I will follow your channel to whatever platform you move to. This is like the educated version of the anarchists cookbook, except cooler for some reason.
Thanks!
Keep it going!
I've been looking at a lot of astrophotography videos lately and seeing the super-slow motion clips reminded me of them. Little specks of burning material illuminating the smoke from the explosion looks a lot like stars floating around the big clouds of dust in the galaxy. They're both the remnants of large explosive events. Reality at different scales resembling itself. (also getting an ND filter for your slow-motion camera might stop some of the blown out details and give you a bit more dynamic range.)
The high speed footage was fascinating. The amount of energy condensed into those small engines is impressive. I look forward to the upcoming videos when you put nozzles on a stack of fuel grains and make something with many Newtons of thrust. I'm not sure what deep, innate sense of ours that pyrotechnics pleases, but it is worth noting that no other species mastered fire, so they could later create fire-works!
Putting a big K-L-M motor in a small, slender rocket and hearing that distant "pop" as it goes transonic is a peak experience for a hobbyist.
But I have a different challenge for you, as once science buff to another. Due to your catholic interest in the sciences, especially electronics, I'd like to see you work on an electronic rocket, an ion propulsion motor. Not only would it be an interesting exploration, but this is a cutting edge area and there may be some interesting new science yet to discover. Perhaps by combining MASER technology with existing ion beams? Just sayin'. Cheers.
Well done Mr. White! 👍
These things look like they'd make amazing fireworks displays.
I watch you videos as often as I can. I enjoy pyro videos and enjoy making black powder of various strengths. in one of your composite shows you showed how balsa was resistant to flame. I experiment with making my own charcoal for my black powder. Pine, willow, hard woods etc. The very best by far is balsa. I would guess it is because of it being pours and we ball mill all the ingredients before we grate it to various grains sizes. We use a launch tube and a golf ball with a given amount of each mixture and time the ball from launch to return to ground. This might be an interesting show. The charcoal and ball milling everything makes all the difference.
I wish I was your friend.. you guys always do cool stuff
epic, it's like new year
Have already seen all at least ones, so I am just waiting for the next. :-)
Nice work. I see you have a playlist set up. Thanks!
This guy is a badass
Hi! Great video as always. I'd like to know whether you're going to experiment with non-cylindrical sections for the axial 'hole' of your rocket engines, so as to play a bit with the area of the combustion front as a function of time. I hope I'm not being too unclear :)
Keep up the excellent work, you guys are inspiring.
Rocket-themed videos are all right, but in my opinion by far the most interesting subject is plasmas and vacuum systems.
Bro. Time for you to have a TV show. This is legendary. The likes of Carl Sagan's 'Cosmos.'
If this guy isn’t building ICBM’s by the end of 2021 I’ll be surprised
Love it
You make science class 🤩 fun
"So that should be kind of exciting." I see what you did there!
Love the content. Please consider a shield for further experiments, be safe.
Oh, yes!
Once the rockets start, shields are mandatory.
Awesome video! maybe a video on the various types of nozzles would be very interesting i think (I don't know if you have already done it)
Not yet. But, there are so many things worth investigating.
What a huge difference in the detonators, one seems to give a huge hot flam while the other gives a big bang without much visible fire! Can the different detonators also have a big effect on the rocket's performance? Thank you for a great video from the Netherlands. 👍🏻
It's a simple idea, but your channel might be the right one to test it: Use a stirling engine that's attached to a fan, that cools its own "cold" piston, to make a portable heater, which accepts all sorts of fuels. This would go well with a campfire and increase its effective heat output.
FYI the beeping can easily be attenuated in post with notch filters at 2450Hz and it's harmonics
Very cool
I’d worry that those hot banging igniters would break the nozzle or otherwise shatter the fuel grain when “contained”.
I was thinking those ignitors would melt the rocket before is left the launch pad.🤔🤣
If you want to expose the flame correctly so that it doesn't overexposes point your camera directly to the sun and expose for that. They have roughly the same Luminance. Learned that trick from the Slowmo guys who often film explosions in Slow Motion.
Might be difficult to do on an overcast day like in the video but you could just preset the camera on a sunny day and save the exposure settings.
Love your channel. Long-time subscriber. Can’t wait to see you test a complete engine. In the meantime, for the sake of my heart condition, maybe create a bit more distance between you and the conflagration?
By the way, despite watching your last video, and having a chemistry background, I don’t really understand the role of BaSO4 in some of your igniters. Could you explain that again? Thanks
The sulfate asds oxygen as well as a catalytic effect that increases the rate of the decomposition of the perchlorate.
Nice
This was very cool and thank you for expanding and sharing the results of your previous testing with these new test grains. A question... Do see any potential issues with the BaSO4 augmented starters; specifically, being too explosive and creating an impulse that damages the engines at starting? Thanks!
Thanks.
I don't think so. The grains are very tough and are designed to operate at pressures in excess of 10 megapascals.
Awesome
I'm liking this series! May I give a shout out to the film side of your productions? Great work! Now If you just had a sound guy to lower that beeping!
Dare I say that I think I saw a slight, "Mad Scientist Smirky Sneer of Satisfaction" when a couple of the explosions appeared to have exceeded your expectations and surprised you? My question though, is this; do you have any bloopers on video that you care to share, or does everything you do always turn out so good? It would be fun and interesting to see. One hundred percent enjoy your videos! Keep em coming!
I really love your vids! Have you ever thought of designing low pressure (high altitude) igniters? The kind to use in 2nd stages; Scott Fintel made some years ago for his high alt (erythritol/sorbitol) rockets. It looked challenging. CHEERS.
Igniters for AP motors need to ignite at the tip of the igniter up against the tracer smoke grain.
And burn down slowly and hot for reliable starts. TRA L3.
Have you thought about field propulsion? The rapid discharge of a high voltage capacitor (preferably unbalanced size plates) creates a longitudinal displacement current that has momentum (thrust).
I haven't, but that's a good idea and worth looking at.
Hey Professor, please disable the beeping on the firing power. Ultimately, it does not promote safety with the constant beeping. One beep, when initially energized is good; or make an enunciator that says "Energized" or such. Or just edit the noise from the videos. It's almost unwatchable with the beeping.
