Warped Perception You make it very fun experience. Keep up great work you crazy. :-) BTW, of you try the ticket thing in a vacuum chamber be great. Show us how it's done by NASA.
This is quite a potentially dangerous experiment. I would like to see a little more up-front warnings about safety issues, such as "Don't try this at home," or "You need such and such grade glass," and "You should wear such and such protection," or whatever. I could just imagine something like this turning into a miniature 'pipe bomb' in someone's unprotected presence.
When I was a kid, I loved designing, building, and flying my rockets! School time naturally got in the way, but I swear, after school time was doing my stupid homework, working on my rockets, and some other teenage boy things that we can't talk about here. Loved the video.
🔴 What Is Islam? ⚠️ 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
Flying rockets when I was a kid. So cool to see the engine in operation. I wouldn't want the video done by anybody else with all their digits. Makes the vid more authentic. ;)
To this day I have an inch long scar on my hand from when I was young and tried to saw open a model rocket engine. This video resolves a childhood curiosity in the most satisfying way possible. I waited 30+ years for this.
+SixOThree wow.. sorry to hear that, I have plenty of those scars, it's a very careful process, and I'm always ready to move out of the way if I see any yellow or orange. It's a bit nerve-racking
I've built plenty of rockets as a kid and have always been in awe of the physics behind these engines...and who can resist the smell of freshly ignited propellant? I've done an in-depth study on rocket nozzles over the past month and I am in awe how the model rocket engines throw a nearly perfect jet (nozzle expansion).
Very cool idea and a great presentation. It would have been nice to see from an engineering standpoint, your thought process in deciding things like the thickness of glass tubing, how you got the parts so precisely matched, failures you encountered, etc. Those are nice to see when showing these videos to students who have this A-Team philosophy of how something gets designed and built and then become frustrated when they fail on one try.
I worked for TRW Safety System’s on airbag propellant which was basically a fast burning rocket motor. We worked on a sub scale test for a simple in process test as a quality control tool. We measured pressure vs time into a closed chamber which simulated an airbag. Our propellant burn was usually over in 100 to 150 ms. (0.100 seconds to 0.150 seconds). Technology was around to visualize the burn but we were more interested in the engineering metric to control quality. The Estes burn is a nice progressive linear burn rate. Perfect for airbags and rockets. Get up to pressure gradually (no detonation please) burn at a steady rate (set the speed control at cruise) sit back and enjoy the ride. Good job. Intellectual curiosity is a gift. Pass it on!
As a preteen I simply unwrapped the paper off the model rocket engine, that simple, no milling machine no nothing but an exposed propellant grain with nozzle and the ejection charge which fell off onto the ground but the grain did not fall onto the ground as I wuz prepared for that contingency being a per-engineer (pre-rocket scientist). Thank you
Sun Tzu thanks for the support. I was reluctant to post this WP on RU-vid but im glad I did because it's grown into something much more connected to the audience. I usually empower people by teaching them, but with this channel I am able to educate and empower others by building their ideas and revealing the normally hidden working mechanisms behind them . I love building things.
Aerospace propulsion engineer here, never ever drill or shock damage the solid propellant, which will cause cracking!!! Cracked propellant is dangerous resulting explosion in the end...
1. I’m intrigued that you had the opportunity to say “actual rocket scientist here”, but didn’t. 2. Why is cracked propellant prone to exploding? PS: I was quite alarmed as well when I saw the saws and drills in the beginning of the video.
This is a perfect playground for experiments. I think there is a lot more efficiency to get from this type of rocket. Using high voltage charge between the tip of the flame and the nozzle would probably speed up the plasma flow. The microwaves at the back of the nozzle could probably speed up the plasma too. Keep on experimenting !
I built many Estes rockets as a kid but only with A and C engines. In the early 1980s, Estes offered D engines with a turquoise blue ink that said "SLD" for "Super Long Delay". A friend of mine explained that the extra-long delay of the ejection means the rocket continues moving up higher before the parachute ejects.
Should put more focus on the ejection charge. That's my favorite part lol.

I saw the first 10 seconds of this, and I thought, "This is going to be a calamity." Mind you, I grew up with this. My family works/worked for NASA and JPL. I am happy to say that I was in error. Very nice video.
+Aténogenes Rojas thank you very much, that means a lot to me coming from a fellow engineer, I am an aeronautical engineer myself. thanks again and I'm glad you liked it !!
Beautiful rocket. One thing to note: a lot of the reason why people use specialized rigs for cutting glass tubing for things like computer water cooling is because they need to minimize the chance of glass dust or cracking of the tube. a glass particle can destroy a pump, and even microscopic cracks in glass can cause issues with structural integrity and longevity of a glass tube containing fluid.
With that same glass tubing, you should make an air piston and ignite different materials. I know they make emergency fire starter pistons to make an ember. I would love to see how quickly the air at the bottom of that piston heats up and ignites things.
+Beau Remington ha !!!. Your right. The smell does bring back memories of my first explosive I built from the crushed rocket fuel when I was 9, also brings back memories of the rockets too !.
Warped Perception spent a summer sans eyebrows doing the same on independence day in 88-89. kids today truly don't know what they're missing. thank you for this, it was worth the nearly 30 year wait to have it visualized this way. you rule.
+Beau Remington it's sad but true, most of my crew is in their twenties, and they always tell me the same thing, they can't sleep the night before a shoot because they have never seen any of the stuff that we film before in their life.
Drilling into a rocket motor is DANGEROUS! I had to learn the hard way myself a long time ago. The friction from the bit ignited the powder and the whole thing went off in my rig/face. I did it probably 20 times before, seemingly the same way, but that time (the LAST time), something went bad. GO SLOW.
Thrust is only generated during the booster stage. Measuring the thrust produced will tell you when maximum output is achieved but the max thrust is labeled on the side of the motor so it's kind of pointless. He was using a C6-7 which is a C class engine producing a maximum 6 Newtons of thrust followed by a 7 second delay charge.
thank you for info, I never used rocket engines. I think that will be nice to see this force in slow motion. By the way you can say that everybody know that it burns and watching this trough a glass pipe is pointless ;)
A lot of motor manufacturers publish data like this. They provide graphs of thrust over time. I just typed "Estes rocket motor thrust curves" into Google and the first link was a pdf with these sorts of graphs. I'd provide a link but links often get trapped in RU-vid's spam filter. The name of the file was "Estes_Time-Thrust_Curves.pdf".
+angrodNumenesse *"He was using a C6-7 which is a C class engine producing a maximum 6 Newtons of thrust"* Is this constant over time? Does it peak at some point? Is average thrust significantly less than stated maximum thrust? Yes I do know the answers, I saw the graphs, I'm just making a point that seeing this actually being measured in the real world would be more fun to watch than just reading it off a graph. Incidentally, from the graphs I've seen, C-6 engines have a maximum thrust of well over 6 Newtons.
+corisco tupi " measured in the real world would be more fun to watch than just reading it off a graph." This is something I plan to do. I have a Chronos 1.4 high speed camera on its way sometime soon and I plan to do all sorts of experiments using it. I have a thrust stand for quadcopter motors and I'm confident I can make a suitable stand for rocket motors. I plan to compare some homemade motors with Estes motors. I'll need to figure out a good way to visualize the thrust while it's being measured.
+Warped Perception i love everything that you've done. just plain amazing. would be great if some day you could make a see through real rocket with oxidizer and stuff work in a vacuum to prove to some people that rocket can work in vacuum. there are real people out there thinking that no combustion can occur in vacuum therefore no one had ever landed on moon and that the earth is flat.. also, personally i am really curious to see how exactly that works internally and there are zero videos about it out there. I believe that would be an amazing video too!
Back in the early 1980s, I remember a class-mate in high school who built his own rocket engines using his own special propellant. I'll never forget the day he showed up at a local rocket launch and damn near wiped out the first row of spectators when his rocket got up about 15 feet in the air and decided to take a 90 degree turn toward the grandstand. I've never seen so many people ducking for cover. If I remember correctly, it was a D or E-sized engine to boot. Seems as though he packed it a little bit "hot". Mike Koss...this one is for you, man.
Warped perception: _lights patch of gunpowder, creating bigass explosion that’s super epic_ Warped perception: That’s cool, smell good Me: excuse what the f u c k
THE SICK BEAT @ 9:08 is ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pzrfeeqGFws.html , show my guy some love, he takes great pride in making his music and its worth a listen, mention WP
Great work showing what happens during the burn. It's the first time I've seen something like this and it gives a great understanding of what occours in flight.
+Warped Perception Could you do a video showing off that Toyota Supra? One of my favorite cars,due to the lines and flow of the car! Or if you have done a video on it already could ya tell me the title to search for? Thanks
aspyromilios the middle one was caught in gears of a large lud-low machine when I was 2, the fore finger happened here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zfvMnTpnKvI.html
Looks like my grandpas cousins hands he was an old time farmer, I almost got attacked by a German Shepard because it was dark out and it panicked, it was really scary because I'm only 105 lbs. I had a knife but I'm glad I didn't have to use it, now I can't leave the house without a blade. Anyway don't let your dogs off leash especially at night because they get really freaked out by dark shadowy figures
i have a 91 *300ZXTT* 750hp.. i knew i liked you... Super car enthusiasts are always more calm and collected.. *FYI* you do Know, that you Will Have to make some sory of epic Ken Block style Giggitty Giggitty 🤠🤔🦄
You would get more subscribers if you didn't wave your hands around so much. I am not saying that to be mean. It is really distracting from what you are saying. You are not a rap star! Also, the hat looks silly. Loved the video and it was awesome to watch! Great slow mo capture.
+alienh1701 lol. Actually now that I mean myself I'm seeing way more traffic on this channel, I'm loaded with explosive energy all the time, I'm at like 10% of my energy in this video. It's going to be awkward but I'm going to try to do it your way and another video oh, that's so RU-vid ish to just look into the camera and talk, just my opinion it's boring. But hey maybe you're onto something, I'll try it out next time. The Hat was a viewer request, definitely not my favorite . thanks for watching I'm glad you enjoyed the video
