Agreed. My one criticism would be lack of clarity in some of the shots. A down camera on a white background cut in for detailed work would be great. E.g. Nile Red
@@VinceDonkovWorks NightHawkInLight is fantastic! Been watching for a very long time now. SmarterEveryday, ElectroBoom, NileRed, Cody's Lab, NurdRage, love them all so, so much!
I agree. So many channels make that mistake. Annoying, repetitive background music is just distracting and unnecessary. If you want to listen to background music, you can always add whatever music you like, but it's much harder to remove it, if you don't want it.
I'd like to see you take a crack at Al-ice rockets (aluminum or magnesium fuel with water ice as oxidizer). I played around with them a little bit as a teenager but only had a few successful ignitions. Tough to get the fuel to ignite without the ice melting and extinguishing the igniter. I think I had some success adding a gel to the ice.
Actually magnesium can also burn with dry ice. Or if you wanna feel REEEEELY nerdy, use CO3! en.wikipedia.org/wiki/Carbon_trioxide Even more violent than those is H2O2m which you can obtain in a [relatively safe] form known as Sodium Percarbonate - en.wikipedia.org/wiki/Sodium_percarbonate Just don't try reacting dry sodium percarbonate with high concentrations of acetic acid ['vinegar' because it produces a highly sensitive explosive, diacetyl peroxide - en.wikipedia.org/wiki/Diacetyl_peroxide

@@NemoConsequentae Yup. Rigid safety precaution protocols are mostly for people who don't know what they're doing, anyways.

I have two recommendations for your firing device: a) Use a guarded pushbutton (EG Grainger P/N 12J255) b) build a circuit to safe it after the button is released so it can't be pressed again until the keyswitch is reset. If you want to get even more extravagant, have a separate low voltage current limited resistance detector that is live when the keyswitch is in the safe position to monitor whether you have a good connection to the igniter, that would light an amber light, and prevent it from arming without that good test (and beep and flash the amber if you try to arm it with an open circuit)
@@daithi007 Not really. Guarded pushbuttons are fine for systems that could be activated with a single action accidentally. The keyswitch already prevents that by requiring a separate, different action to arm the system, and you have two indicators showing system state besides. Yet another guard doesn't add to safety in a unique way, it's just redundant. Circuits to disarm on ignition don't make sense either since the igniter has to be replaced, it automatically can't fire again anyway. Low voltage detection is probably impractical or dangerous depending on wire length due to voltage drop, either you can't reliably detect a good circuit, or you have to get the voltage high enough to account for losses and that could cause ignition just from testing. It's a terrible idea to suggest putting electricity through the igniter when it's that electricity that fires it off. There's systems that can do that, but they're not using homemade igniters. Finally, you don't gain safety by checking for open circuits since an open circuit on an igniter fails to a safer condition, which is "no ignition." There's no penalty for pushing the button on a disconnected igniter other than "your rocket doesn't fire."
@@Pyrichia Continuity checking for the rocket igniters has been done safely for decades. Using Kirchhoff's Voltage law and calculating the voltage drop across the relatively small rock igniter resistance compared to the series lamp resistance and using voltage division is how such systems are designed. It's too bad YT does not allow pictures and LaTeX like equations in the comments.
@@organizedfromwithin2525 reminding me of things I should have remembered from other domains; you're right. You can check continuity without setting off an igniter.
So how about mounting it to a base with two spring return key switches 6 feet apart and a momentary contact pish button to fire. The idea is taking two people each holding their switch closed and with one of the remaining hands, pushing the fire button. If you use two buttons in series next to the key switches, a contortionist would have trouble firing it by themselves! You can add in lights like he has in his circuit. Of course you could just pull the ignitor wires and connect to a battery! But if you want to add some drama to your rocket launches, this will do it!
I have seen some very good and informative articles on TH-cam. This one is the best. At 63 years of age. You have given me the inspiration to start building model rockets.

I stumbled on your site today. Name is Tom, I’m 59. I won a 6 grade science comp w with Estees rockets. I’ve played with firearms as far as one could go, internal combustion engines w blowers and tourbo charging, can’t afford the racing thing anymore, but I can do the rocket thing again. Well thank you sir for reignighting my interest , this will fight the boredom and depreciation I’ve felt scince back surgery . Thank You
As a person who would love to do these kinds of projects, I want to thank you for presenting them so thoroughly. You are one of two channels I have set to send me notifications on new uploads. Thank you!
I love the work you have been doing! It's good practice to short the leads of your igniter before applying any pyrogen, keeping them shorted until you are ready to use them, this prevents any accidental charge from setting off the igniter.
I love the fact after watching one of your videos I leave just a little smarter thank you so much for what you do. I’m a retired engineer so I have time on my hands
I can’t tell you the level of excitement I feel when I see a new upload in my newsfeed. I think “yes! Over 30 minute video” But I must get so engrossed because the end credit music fades in far too quickly! “Admit it..... it’s pretty good” with a huge smile on your face. I was grinning like a Cheshire Cat. Thank you guys, you have made such a difference to my mental well being during this second lockdown over here in the U.K.
This channel has been an absolute blessing to me and my daughter who is only 15 but already taking flight lessons due to her astonishing work at space camp this channel has allowed me to communicate with her on so many different levels I would never have previously understood thank you so much keep up the good work !!
When connecting the starter at the rocket, use a thick cable with alligator clips to short the signal comming in from the launch control. If there was ever a stuck contact or a capacitive discharge, the energy would be shorted and could prevent an accidental ignition.
Your point is well taken, but, with the air gaps in the industrial switches used in this system it's probably not needful. Both the key and the palm button should be OPEN when connecting igniter leads. It would have to be a relatively powerful transmitter to bridge those switches while they are open. Systems I've used in the past had a high resistance continuity lamp circuit which indicated a good igniter connection once the ARM switch is made, but restricted current to levels well below that required for ignition. With such a system, yeah, RFI could be a problem, but not here.
I am a fan. You have got to be the most well spoken, thorough and very obviously, well versed youtuber/personality I've seen to date. Thanks for a great lesson! I as well as I'm sure many others will look forward to what you'll share with us next. Brandon
I absolutely love your videos , very detailed , step by step , ingredients , but even better is you explain every part . The safety aspect of all your projects are awesome as well so I know what the dangers are . Your videos as 100 percent correct and work , you have earned my trust in video selection for projects
Excitement and relief! Discovering your channel has made the breakthrough possible for me. I became complacent with sub-optimal results from dozens of rocket launches. Thank You So much for your very detailed lessons.
I've never commented or interacted with the TH-cam community before despite years of watching videos. But this deserves some thanks for such great content. Truly inspiring stuff !!! i'm sure i speak for everyone when i say please do a couple of more videos, build a fuselage and rocket body, launch these babies into the sky somewhere!
This is Tech Ingredients. We all know he's going to science and engineer the heck out of these. I'm looking forward to the hybrid engines myself. Possibly using cryo LOX and Perchlorate. Ofr course if you wanted to take us on a guided tour of the book Ignition possibly with a collab with Nile Red that would be really interesting. Incredibly dangerous, but definitly interesting......
Thanks for being brave enough to make a video like this- it’s immensely interesting, and most folks would have gone the “somebody might blow themselves up...” route. Very well done- thanks.
Takes time to create excellent content and this was worth waiting for. I'll take quality over quantity any day. You are doing very well. Continue to take as much time as is necessary.
i really appreciate that you clarify the MKSA units. because for non US citizens it's quite difficult to calculate in imperial. Nice content by the way.
Great video!! Would you have any interest in doing a video for making a primmer for pistol and rifle cartridges? There is a massive shortage right now and I think it would be fun to pay with Keep up all the great work!! Really awesome

Can I get a shout out for telling you about core and end burners in your last video? And you can still core burn with a fuse. Just wrap all but the end of the fuse with electrical tape.
In my younger days I made engines with Zn dust and S flower. Worked very well. My standard testing fuel was Caramel Candy( Sugar and KNO3) Thank you for all your Videos, I find them very enjoyable.
I really enjoy your videos. No flashy gimmicks, straight forward insightful information with a proper emphasis on safety. Bravo guys well done and thank you for all the useful information. This will be very helpful in furthering a great hobby interest for my son and I to enjoy.
When you showed off the ignitors, it was a little annoying that whenever the video cut to another camera angle the ignition came immediately. I'd suggest adding half a second of video after the cut for the viewer to adjust to the new camera angle and to find the "point of interest" in the frame before ignition occurs. Otherwise a great video!
Thin nichrome is used as the bridge wire in e-matches. You can make a nitrocellulose lacquer for coating using ping pong balls and acetone. The lacquer and smokeless powder makes a decent, simple e-match compound...
MON CANARD EST EN FEU! www.schlockmercenary.com/2005-06-22 I'm also thinking of the gulls on the SpaceX barge during their last attempted landing. (Looks like engine malfunction during reentry burn, missed it entirely.) Lucky gulls...
I think your quality videos should earn you a lot more followers! You have so much to show the world. I have great respect for everything you do, I like the long videos with a lot of information. Thank you so much! 🍀
Man, this channel is so informative, that it really get into the fine grit of the information, and really makes you understand the stuff that you are looking at. Makes me want to do EVERYTHING they make!
As usual, an outstanding video.... Two points I want to share: 1) An additional safety measure is to shunt your wires together to eliminate incidental charge build up at the ignition compound. This ensures risk of ignition is mitigated when you DO NOT want to ignite the compound. 2) The "shelf life" of the Al powder and NH4ClO4 mix is not that long. In other words, make the igniters at the last possible moment before you want to fire them. 24 to 48 hours is typically okay but your mileage will vary on home-brew ignitors...so experimentation is warranted to determine your time intervals and associated confidence levels for good ignition. In short, do not make up a bunch of igniters and expect them to work a year from now.
You are easily one of the smartest youtubers who does science videos. I love the way you explain the subtle details and particularities of everything you are working with. Very in-depth educational content. You have my subscription and my eternal likes, sir.
aka IEEE1394. For a while "firewire" wasn't used, and IEEE 1394 used, instead. This was partially because a fancy speaker wire company (like Monster Cable, but don't recall which one) was using it as a trademark. The two businesses were too close together, in category, so the data protocol vendors, just avoided the name.
Firewire from back in the day. You have a webcam that supports Firewire? It's not like any of those cameras of that era needed that kind of bandwidth. Power hungry, somewhat flaky protocol.
You really should teach a seminar at PGI. They would love you. I started with Estes rockets in the 60's. Graduated to high power rocketry later in life and now my main hobby is fireworking. The PGI convention is scheduled to take place in Fargo, ND August 7-13. It is definitely a bucket list thing to do. You would fit right in. This was a great video.Thank you sir.
Y'all did a good job with the zooms and such on this vid. Thank you for that. You're vids get better everytime. They're all excellent knowledge regardless.

A quick sneak peak for an intro is a perfect idea... one can expect what is approaching you... please keep it that way... Ps. I'm a great admirer and fan of yours... cheers
My grandfather taught me the same trick with shorter wire on one side. Another trick he showed me is, if they are the same length, clip one wire onto itself down further. Same with Jumper cables.
Coming from the fireworking side of rocket making. I would want a little more distance from my rocket engine in case of a CATO! I just found your channel and I love it! Truly well done! Thank you!
I make a point to watch all the videos on your channel even if I'm (very rarely) not so interested in the topic, because there are constant gems of knowledge scattered throughout. For example here I learnt that IPA is an excellent temporary lubricant for silicone and wished I knew that before! I don't often comment on videos, but these deserve it. If it's something you would consider, I'd be very interested to hear more about your and your son's background as you seem to have knowledge and interest in such varied fields. Thanks for providing such excellent content.
When it comes to ignition and back pressure during the process, there are advantages to managing that oressure. A self oxidating fuel ingites faster and much more evenly through the center core when under some pressure. Many rocket designs use a rupture disc set inside of the nozzle. The disc has two scores that can be altered to create more or less pressure during ignition. When the pressure is reached, the scores which are the designed weak points will fail allowing the thrust to instantly occur. This effect with the optimim nozzle orifice, can help manage your motor characteristics. Great video. Thank you.
Hi Tech Ingredients, Thanks for the awesome in depth videos. I appreciate the calm pace and the long videos. Your channel is what I always wished Discovery channel would be. Here is a list of suggestions 1. How to do color effects in pyrotechnics. 2. Explore the loudest bang effect of pyrotechnics. The optimal ratio for loudest report. 3. Alternatives to black powder in pyrotechnics.
You should upgrade your launch controller to detect whether the circuit is made by passing a very low current through the e-match. This is how Estes does it with their little launchers - the light bulb actually makes its circuit through the e-match, and then the switch simply shorts out the lightbulb to allow more current to flow and achieve ignition. You could then have some automated troubleshooting built into the launch system that would detect both shorts and opens and indicate the problem to the operator.
Living in the Netherlands, (where you can forget buying these products) I absolutely LOVE your videos. I'm 65 and I used to make black powder rockets in South Africa (illegally) but man, if these videos were available in those days, I would have beaten the Mars rovers to Mars. Brilliant indeed.
@30:36 This candle is definitely not suited for a birthday cake ... wishes will get lost in space. Thank you very much for your excellent video as always! Now I finally believe you are a rocket science engineer in your profession.
Awesome videos! I really like the different variety of videos you make, especially anything chemistry- or electronics-related. I went into computer science, but I still love learning about chem & EE. One thing that would help make your videos even better would be to put a little piece of foam over your lapel mic so your plosive consonant sounds aren't super loud on the audio recording. Sometimes the fuzzy thing people put over boom mics is called a "deadcat" - which is kinda funny. Another thing that helps with audio is to do a very rapid fade in at the beginning of cuts and a very rapid fade out at the end of cuts to stop any sort of unintentional clicking noises between cuts. Both of these things are pretty minor, and usually only headphones users or audio engineers notice. Thanks for making these videos!
Hi! I just wanted to give you a suggestion: Have you considered making an air purifier? Something like a cycloner, blowing air into mineral oil or other liquid that don't evaporate, an electrostatic precipitator, EPA filters, or a combination of those and whatever you come up to. Cycloners cause static, you can source baby oil for cheap and scented mineral oil, electrostatic precipitator can cause Ozone, and the different EPA filters will need different air pressures. I'm sure you can make it an interesting subject.
I appreciate the modified warning and encouragement to seek out someone experienced if you're unsure. I like that so much more than to just not ever attempt. Subtle, but I hope young scientists are encouraged that way today.
I'm gonna dream of rockets and reversing trucks tonight
Fire in the hole.

I am a fan. You have got to be the most well spoken, thorough and very obviously, well versed youtuber/personality I've seen to date. Thanks for a great lesson! I as well as I'm sure many others will look forward to what you'll share with us next. Brandon
This is the only channel I watch EVERY upload from.
😀
I absolutely love your videos , very detailed , step by step , ingredients , but even better is you explain every part . The safety aspect of all your projects are awesome as well so I know what the dangers are . Your videos as 100 percent correct and work , you have earned my trust in video selection for projects
Thank you!
I like how a car drove by at 30:10. Driver probably said to his wife, “Martha, he’s at it again”.
I love his deadpan expression as the car drove by. They were probably thinking, "the crazy guy is lighting stuff on fire again".
Excitement and relief! Discovering your channel has made the breakthrough possible for me. I became complacent with sub-optimal results from dozens of rocket launches. Thank You So much for your very detailed lessons.
Good luck.
This guy is like Mr Wizard of the internet
spaceX needs to hire this guy ASAP
Mr Wizard was a kid's show.
No. He is God. He knows everything!
@@alexrXX Close, unlike Somebody, he knows when he _doesn't_ know everything! But then proceeds to figure it out!
@@michiganengineer8621 True! But God is also still figuring out how to make a perfect universe.
2:20 this doubt was killing me for a while now glad u clarified it
As always, great video from my most favourite channel!
I've never commented or interacted with the TH-cam community before despite years of watching videos. But this deserves some thanks for such great content. Truly inspiring stuff !!! i'm sure i speak for everyone when i say please do a couple of more videos, build a fuselage and rocket body, launch these babies into the sky somewhere!
Man, you should attach those motors to a load cell and graph the thrust over time. I'm interested in how that long burn performs. Nice job!
he will do thrust measurements
Yes. I'm no expert but it seemed a very long time for such a small motor. Hard to imagine it could produce enough thrust to launch a rocket very high
No nozzles.
The burn rate is slow, as it is pressure dependent. Without a nozzle, the chamber pressure is very low and it burns longer than in a real flight
This is Tech Ingredients. We all know he's going to science and engineer the heck out of these. I'm looking forward to the hybrid engines myself. Possibly using cryo LOX and Perchlorate. Ofr course if you wanted to take us on a guided tour of the book Ignition possibly with a collab with Nile Red that would be really interesting. Incredibly dangerous, but definitly interesting......
Thanks for being brave enough to make a video like this- it’s immensely interesting, and most folks would have gone the “somebody might blow themselves up...” route. Very well done- thanks.
I would really like to see you put each entire series onto a dvd as you get them completed and put them up for sale. I would purchase them. Thank you.
I have a lot of work ahead of me. First building the rockets , engines ,ignitors and last the launch controls. Thank you for another great video.
so once it's popped, turn the key off.. that beeping is... excessive
yeah, funny how he waits with his hand on the key for the flame to go down before shutting the bloody thing off lol
No kidding
Great video!
It's like the viewers themselves doing the experimenting, minus the dangers involved in the experiment.
Thank you, and stay safe, too!
Takes time to create excellent content and this was worth waiting for. I'll take quality over quantity any day. You are doing very well. Continue to take as much time as is necessary.
i really appreciate that you clarify the MKSA units. because for non US citizens it's quite difficult to calculate in imperial. Nice content by the way.
Great video!!
Would you have any interest in doing a video for making a primmer for pistol and rifle cartridges? There is a massive shortage right now and I think it would be fun to pay with
Keep up all the great work!! Really awesome
This is why i stick with my "old" Colts and Remingtons.
Extremely dangerous fabrication. I think Cody's Lab made one long ago, but probably he had to take it down somewhere along the line.
I just recently saw a YT video on that subject.
@@benthere8051 with elvis ammo?!
He's got a great channel!
They should collaborate
Momma's shaking her head from the kitchen thinking what have i gotten myself into LOL Love your professional approach doing back yard science and ingenuity "necessity is the mother of invention".
Can I get a shout out for telling you about core and end burners in your last video? And you can still core burn with a fuse. Just wrap all but the end of the fuse with electrical tape.
You did mention that.
I'm glad I'm not the only person who cuts conductors at different lengths. I'm glad to see I'm in good company.
Main Presenter was definitely either a professor or worked at NASA.
Professor for sure he is...and NASA, that was also my thought.
Well , I'm betting 3m or some company similar .
In my younger days I made engines with Zn dust and S flower. Worked very well. My standard testing fuel was Caramel Candy( Sugar and KNO3) Thank you for all your Videos, I find them very enjoyable.
LOVE YOUR CHANNEL... just sitting here wondering how many of us, having watched (nearly) all of your vids, are now on multiple "lists" lol
I really enjoy your videos. No flashy gimmicks, straight forward insightful information with a proper emphasis on safety. Bravo guys well done and thank you for all the useful information. This will be very helpful in furthering a great hobby interest for my son and I to enjoy.
When you showed off the ignitors, it was a little annoying that whenever the video cut to another camera angle the ignition came immediately. I'd suggest adding half a second of video after the cut for the viewer to adjust to the new camera angle and to find the "point of interest" in the frame before ignition occurs. Otherwise a great video!
Thin nichrome is used as the bridge wire in e-matches. You can make a nitrocellulose lacquer for coating using ping pong balls and acetone. The lacquer and smokeless powder makes a decent, simple e-match compound...
1:45 - Well, toast my ducklings! (that would be, bad).

I'm also thinking of the gulls on the SpaceX barge during their last attempted landing. (Looks like engine malfunction during reentry burn, missed it entirely.) Lucky gulls...
I think your quality videos should earn you a lot more followers! You have so much to show the world. I have great respect for everything you do, I like the long videos with a lot of information. Thank you so much! 🍀
Thanks!
Spread the word.
The beeping is truly awful. Great video otherwise
Oh dear Brian. I do hope you’ve recovered
Excellent as always. I particularly liked the line 'I used one of our smaller drone batteries' - [pulls out a battery the size of a house brick]
You are a highly respected God amongst us tinkerers, thank you for your information and info!!!
Man, this channel is so informative, that it really get into the fine grit of the information, and really makes you understand the stuff that you are looking at. Makes me want to do EVERYTHING they make!
I want to be on your team when the aliens invade hahaha
As usual, an outstanding video....
Two points I want to share:
1) An additional safety measure is to shunt your wires together to eliminate incidental charge build up at the ignition compound. This ensures risk of ignition is mitigated when you DO NOT want to ignite the compound.
2) The "shelf life" of the Al powder and NH4ClO4 mix is not that long. In other words, make the igniters at the last possible moment before you want to fire them. 24 to 48 hours is typically okay but your mileage will vary on home-brew ignitors...so experimentation is warranted to determine your time intervals and associated confidence levels for good ignition. In short, do not make up a bunch of igniters and expect them to work a year from now.
I've found these will last for months without a misfire, but I'd advise against storing them (as I've done) primarily because they are so flammable.
Your shirt looks like when you zoom into an LCD screen

You are easily one of the smartest youtubers who does science videos. I love the way you explain the subtle details and particularities of everything you are working with. Very in-depth educational content. You have my subscription and my eternal likes, sir.
Thanks and welcome!
Latching timer relay would be nice to activate buzzer for 2 seconds then turn off
If only life was so kind as to let you pick your own mentor... it would be you. Great job as always!
Forces his son to “admit it”, that was pretty good.
You are great teachers! Very good camera work and presentation speed!
You should do a colab with bps.space!
I would also like to add that I appreciate you making your level of knowledge accessible to the common layman thank you very much
Firewire?I'd like to connect an old webcam to an old computer using that.
aka IEEE1394. For a while "firewire" wasn't used, and IEEE 1394 used, instead. This was partially because a fancy speaker wire company (like Monster Cable, but don't recall which one) was using it as a trademark. The two businesses were too close together, in category, so the data protocol vendors, just avoided the name.
Firewire from back in the day. You have a webcam that supports Firewire? It's not like any of those cameras of that era needed that kind of bandwidth. Power hungry, somewhat flaky protocol.
You really should teach a seminar at PGI. They would love you. I started with Estes rockets in the 60's. Graduated to high power rocketry later in life and now my main hobby is fireworking. The PGI convention is scheduled to take place in Fargo, ND August 7-13. It is definitely a bucket list thing to do. You would fit right in. This was a great video.Thank you sir.
Was wondering when you'd publish a new video
Y'all did a good job with the zooms and such on this vid. Thank you for that. You're vids get better everytime. They're all excellent knowledge regardless.
Great, but get rid of the bleeping....if not completely, at lest once the starter has been pressed....had to mute your video!
Tons of respect for using metric scales! You're awesome
Next time please turn off the beeping after ignition.
Definitely a fun, interesting, and I like the step by step with safety procedures. Of course the live fire is so thrilling.
Wow ! This was a whole lot of FUN ~! I enjoyed every aspect of this so far and I can't wait to see the rest of the progression ! I am a total science enthusiast and I really appreciate all of the thorough explanations and fantastic demonstrations...Great Job !!
Wow, I'm impressed, I build my own rockets. Commercially, I can only get E motors, I want to go bigger, and fly higher.. Well done with your explanation of the igniters. Well done.. I get it know.. Good job, love your content!
A quick sneak peak for an intro is a perfect idea... one can expect what is approaching you... please keep it that way...
Ps. I'm a great admirer and fan of yours... cheers
My grandfather taught me the same trick with shorter wire on one side. Another trick he showed me is, if they are the same length, clip one wire onto itself down further. Same with Jumper cables.
Coming from the fireworking side of rocket making. I would want a little more distance from my rocket engine in case of a CATO! I just found your channel and I love it! Truly well done! Thank you!
Thanks.
I was standing pretty close, but these were not engines they were only test grains of various propellent formulations without nozzles.
I make a point to watch all the videos on your channel even if I'm (very rarely) not so interested in the topic, because there are constant gems of knowledge scattered throughout. For example here I learnt that IPA is an excellent temporary lubricant for silicone and wished I knew that before!
I don't often comment on videos, but these deserve it.
If it's something you would consider, I'd be very interested to hear more about your and your son's background as you seem to have knowledge and interest in such varied fields.
Thanks for providing such excellent content.
When it comes to ignition and back pressure during the process, there are advantages to managing that oressure. A self oxidating fuel ingites faster and much more evenly through the center core when under some pressure.
Many rocket designs use a rupture disc set inside of the nozzle. The disc has two scores that can be altered to create more or less pressure during ignition. When the pressure is reached, the scores which are the designed weak points will fail allowing the thrust to instantly occur. This effect with the optimim nozzle orifice, can help manage your motor characteristics. Great video. Thank you.
Hi Tech Ingredients,
Thanks for the awesome in depth videos. I appreciate the calm pace and the long videos. Your channel is what I always wished Discovery channel would be.
Here is a list of suggestions
1. How to do color effects in pyrotechnics.
2. Explore the loudest bang effect of pyrotechnics. The optimal ratio for loudest report.
3. Alternatives to black powder in pyrotechnics.
You should upgrade your launch controller to detect whether the circuit is made by passing a very low current through the e-match. This is how Estes does it with their little launchers - the light bulb actually makes its circuit through the e-match, and then the switch simply shorts out the lightbulb to allow more current to flow and achieve ignition. You could then have some automated troubleshooting built into the launch system that would detect both shorts and opens and indicate the problem to the operator.
We could add an ohm meter and get integrity as well as overall system resistance.
Living in the Netherlands, (where you can forget buying these products) I absolutely LOVE your videos. I'm 65 and I used to make black powder rockets in South Africa (illegally) but man, if these videos were available in those days, I would have beaten the Mars rovers to Mars.
Brilliant indeed.
@30:36 This candle is definitely not suited for a birthday cake ... wishes will get lost in space.
Thank you very much for your excellent video as always!
Now I finally believe you are a rocket science engineer in your profession.
this rocket series is awesome! in-depth on both theory and safety, well explained and everything is shown with no time wasted. just awesome! thank you
Another *EXCELLENT* video.
Well done, again.
Awesome videos! I really like the different variety of videos you make, especially anything chemistry- or electronics-related. I went into computer science, but I still love learning about chem & EE.
One thing that would help make your videos even better would be to put a little piece of foam over your lapel mic so your plosive consonant sounds aren't super loud on the audio recording. Sometimes the fuzzy thing people put over boom mics is called a "deadcat" - which is kinda funny.
Another thing that helps with audio is to do a very rapid fade in at the beginning of cuts and a very rapid fade out at the end of cuts to stop any sort of unintentional clicking noises between cuts.
Both of these things are pretty minor, and usually only headphones users or audio engineers notice. Thanks for making these videos!
Hi!
I just wanted to give you a suggestion: Have you considered making an air purifier? Something like a cycloner, blowing air into mineral oil or other liquid that don't evaporate, an electrostatic precipitator, EPA filters, or a combination of those and whatever you come up to.
Cycloners cause static, you can source baby oil for cheap and scented mineral oil, electrostatic precipitator can cause Ozone, and the different EPA filters will need different air pressures. I'm sure you can make it an interesting subject.
I appreciate the modified warning and encouragement to seek out someone experienced if you're unsure. I like that so much more than to just not ever attempt. Subtle, but I hope young scientists are encouraged that way today.
Solid video 🤙really wish I had a teacher like you in school. Thanks for the awesome content
Good to see safety details and explanations as well as safety goggles.
