Excellent, informative video. I will definitely recommend this video for viewing to young rocketry enthusiasts. Special thanks for mentioning Tsiolkovsky. He is an amazing person. The scientist is self-taught, whose ideas were ahead of time. I was several times in the city of Kaluga, where he lived and worked as a schoolteacher. There is now a museum dedicated to his life. On May 10, 1897, Tsiolkovsky derived a formula that established the relationship between the speed of a rocket at any moment, the rate of outflow of gases from a nozzle, the mass of a rocket, and the mass of fuel. After completing the mathematical notes, Tsiolkovsky mechanically set the date: May 10, 1897, thereby securing his primacy in matters of the scientific exploration of space. (It should be noted that in general, the equation of motion of a body with a variable mass was derived at the beginning of the 19th century).
Thank you for the fantastic review of the video! You obviously know a lot about Tsiolkovsky and the history of his discovery. We believe in giving proper attribution because it is done so infrequently in recent times. You would be amazed by how many sites that just use the name "Rocket Equation" that I came across while researching this video. Some of the most successful people that I know are self-taught, and that is something that should be lauded as a great accomplishment. I did not know this about Tsiolkovsky, so thank you for pointing this out. I am even more impressed now!
The way of Tsiolkovsky to knowledge and science is amazing and complicated. Owing to the illness suffered in childhood and partial hearing loss, the young Tsiolkovsky could not continue his studies in the gymnasium on a par with his peers and after 3 years of study, was expelled for academic failure and bad behavior. Then he continued self-study and passed the exams for the post of district teacher. Difficulties in communication and non-systemic education left an imprint on many events in the life of K.E. For example, while still very young, Tsiolkovsky independently developed the kinetic theory of gases and sent the manuscript to the Russian Physical and Chemical Society in St. Petersburg, shortly before this founded by D.I. Mendeleev. Soon he gets a response from Mendeleev, which has something like this: the kinetic theory of gases is already open ... 25 years ago.
@@WATERROCKETSCLUB That is an incredible story. I will search and see if I can find a good documentary on his life and his work. He sounds very much like a colleague of mine. Thank you for opening my eyes to his rich background. I am intrigued to learn more.
Congrats on Passing 10.000 Subs lately! I hope that you will continue with this series soon, I'm really looking forward to it! However, I've got one more question concerning the system: are you using a non-return valve to keep the water in the top stage? Thank's in advance, Love your vids! 😃
Why did you stop uploading videos now? This project has been really interesting and it would be amazing if you start releasing videos again. It's been 3 years!
can't wait to see the next part and how you have made the staging mechanism fully electronic are you using pressure sensor or accelerometer for the staging timing
@@fromaflafl2198 The plan is to dedicate more time to editing videos so we have more frequent uploads. There are some projects we're excited to share. The electronics we're currently using are using the custom PCB miniaturized version of the MSP430 LaunchPad AlTImeter. We have some other plans for future electronics, but this is in the planning stages.
Very well made and informative video! :) Looking forward for more details about project Gemini! I think one important aspect of staging water rockets is, that most excisting staging mechanisms are quite large in comparison to the rocket. Also, the stager weight to total weight ratio of water rockets is a lot worse than of "real" rockets or pyro model rockets. It's also incredible hard to build a stager that can withstand the high acceleration common for high performance water rockets. I think these are the reasons why nobody has tried to break altitude water rocket records with multiple stages until now. However, with 3D-printing and composite material becoming more available for everyone this is changing. It would be an enormous achievement if you are able to overcome this issues with your design, and it looks quite promising. :) Have you tested it with higher acceleration on your record breaking rockets? All the best! Julian from Raketfued
I'm doing a bottle rocket project for school. What fin shape is best for long air time? I've heard elliptical fins are the most aerodynamic. What advantages do a clipped delta or other shape have over this?
Great video. very well explained in a simple and easy to follow way! Yes.. the tyranny and the beauty of the rocket equation. There is a reason we have (so far) not seen a true single-stage to orbit rocket.... math and physics! Looking forward to see how you do the stage separator design. I have only tried building single stage water rockets, and I have looked at staging designs but I am intrigued by yours. Good luck on the record breaking attempt!
Thanks so much for the encouragement! I will put the finishing touches on the stager video as soon as I can. The comments here are really getting me fired up!
If you put a smaller opening at the bottom of the rocket, would that make a difference? Let say instead of a 1" opening, you go to 1/2" opening and increase the air pressure to 200 psi, like when you put your thumb at the end of a garden hose, it makes the water go further, wouldn’t it be the same with a rocket?
We have not experimented with other liquids, primarily because we compete in the WRA2 sanctioned competitions, which forbid using anything but air and water as the propellant.
From watching the end of your video it looks like you are working on a new electronic control? Any available information yet? Looking forward to seeing this new project. Keep up the good work. Cheers Willy
@@willywgb There's actually two different electronics designs shown in the video. One is a sort of combination PCB with multiple functions that plugs into an MSP430 LaunchPad and takes advantage of the LaunchPad Ecosystem to leverage readily available peripherals like a touch-screen. The board itself has an SD-card for Datalogging, instrumentation amplifiers for reading pressure transducers and load cells, and has a bunch of servo and brushless motor outputs. We have used that board for a lot of support projects, but the goal of that board was to control an autonomous launcher that fills to a preset pressure and monitors for safe conditions and then launches the rocket.
The whole worldwide virus thing happened and it really has been taxing on the team and especially my video editor. I've got several projects backlogged now and have started learning to use DaVinci Resolve to try and publish more videos. Thanks for showing you're interested in the series!
He isnt gone he is just perfecting this for us :)

I see your staging mech is 3d printed! Interesting how a bottlecap is used to stabilize the structure!

buddy, this vidoe uploaded 4 years ago. Pretty sure this channel is inactive.
Any updates? I feel like I've been waiting in anticipation for years to see your staging mechanism in action. haha Love the vids!
Why did you stop uploading videos now? This project has been really interesting and it would be amazing if you start releasing videos again. It's been 3 years!
Love the way you explain it hope you will carry on ,and I love the fact that there is a club for just making water rockets
can't wait to see the next part and how you have made the staging mechanism fully electronic are you using pressure sensor or accelerometer for the staging timing
All the video has been recorded. It just needs to be edited. Very happy to hear you are excited for this project! Cheers!
@@USWaterRockets are you planning semy weekly release and are you still using the MSP430 to control the staging ore movt to Arduino or similar

Wow your staging mechanism looks great! Good luck on your record attempt!

LOVE THAT Spacex logo on the rocket...
Such an interesting Video! I tried t build a Water Rocket on my own and will use your Website to improve. Thank you very much 👍🏼
When is the next video going to be uploaded? It's been 10 months

What is the easiest method of doing it without mechanics?
Have you tried lpg instead of water on a hot day?

Love your videos. Very good information to learn. Please keep making them. Really like this two stag rocket design.

Why didn't you upload videos now
What is your website?
What happened to the project? I've been waiting for more videos for a long time now.

@@USWaterRocketsKeep up the good work! Thanks for inspiring me to start building my own rockets.
Can I please get the files for the r2 droid
it‘s really help me，thank for the video。
No new videos for 4 years hopefully everything is ok
We WANT NEW VIDEOS!!!
What happened to the channel?
Думаю 3 года назад кто-то вряд ли рассчитывал на то, что это видео в будущем поможет 9-ти класснику с домашкой по физике
Just hoping you guys are still going ok?
Love the stick figures
Been awhile!
You know how it is, life happens. We have quite a backlog of footage to edit and publish videos about. Hopefully the upload frequency should improve!
@@USWaterRockets amen brother glad to see you back on here!!
Thanks for providing the motivational feedback!
@@USWaterRockets anytime always on here!
Wooow
What happened? are gona quit at least finish this series
Супер!
CNBC
I hated this video! Just kidding it was great.
Well subscrive ciao ciao nuovo canale urbex Il
