Great video and launcher design. Best method I've seen yet. Compact, lightweight, minimal effort involved to construct = 100% FUN!!!

[@mateocontenla5916]

Just wanted to say that in my 3 months experience designing and launching water rockets, you have inspired me a lot, congratulations

[@RaketfuedrocketsDeutschland]

Mateo Contenla Wow, these are really nice words! Thank you! :)

[@datfloof2732]

Sheesh that thing went high, love how easy this is, and the garden hose is something i would never thought of using

[@michaeltobin2458]

Thanks for all the ideas , great videos my son is going to love making and launching this.

[@AirCommandRockets]

Very nicely done tutorial guys! Very clean editing and easy to follow instructions. I'll recommend this video when people ask how to get started with water rockets. :)

[@RaketfuedrocketsDeutschland]

AirCommandRockets Thanks a lot for the nice words George, and thank you for your help as well. :) Great to hear that you like it. Cheers Julian

What brand is that garden hose QD set? I’m in America and my local hardware shops the female threaded QD pieces are too small a diameter for a bottle cap.

[@leobetancourt6758]

very nice señor

[@andrelindolfo4111]

Good evening, is there any video of yours that teaches how to make 2-stage rockets and especially the mechanism for releasing the first stage and activating the second stage?

[@verargertesspielen4629]

Ich finds krass, dass ihr euch so viel Mühe gebt, und jedes Video in Englisch und Deutsch hochladet. Respekt :)

[@RaketfuedrocketsDeutschland]

UpsetGaming Dankeschön. :) Ich denke viele unterschätzen den Aufwand, den so ein Video macht. Wir hatten vier Drehtage, und ich saß drei komplette Abende (jeweils mindestens 4 Stunden) am Schnitt. Gestern habe ich fast den ganzen Tag damit verbracht die Videos zu vertonen und das Color Grading zu machen. Das englische Skript hat George (von AirCommandRockets) freundlicherweise korrigiert und verbessert, und das alles dann wieder einzusprechen ist ziemlich viel Arbeit. Vor allem gibt es durchaus Unterschiede zwischen den beiden Videos. Die ganzen einzelnen Clips müssen an die andere Vertonung angepasst werden, manchmal müssen Szenen ausgetauscht werden etc.. Die Animation der Webseite zu Beginn (bei der Erwähnung der Materialliste) musste nochmal neu erstellt werden, damit der Text auch auf Englisch ist, und so weiter. Dann muss noch die Materialliste übersetzt werden. Rendern in 4K dauert schon mal zwei Stunden, die Ausgabedateien sind ca. 1,5 GB groß. Das ganze wurde dann über Nacht hochgeladen. Heute morgen schnell alles verlinkt, und fertig. :D

[@verargertesspielen4629]

RaketfuedRockets Was hast du denn für eine Internetleitung? 1,5 GB ist schon ganz schob viel, gerade bei 2 Videos. Hast du auch nen guten PC fürs Rendern? Weil 4k ist sehr anspruchsvoll...

[@RaketfuedrocketsDeutschland]

UpsetGaming Das Internet ist gut genug, der Upload von einem Video hat ca. 3 Stunden gedauert wenn ich mich nicht täusche. Der PC ist ebenfalls gut genug, habe den extra für solche Aufgaben gekauft. :)

[@jpna8223]

Hey, in school, we use a 1.5 liter bottle. Do you have tips on how we can fit the bottle cap and connect it to the launch mechanism?

[@kisa74]

Should the bottle connecter and the main connecter should be easy to separate when pulling the string as I am going through some hose fittings thanks

[@milifernandez2900]

Awesome !!!

[@RaketfuedrocketsDeutschland]

Thanks!

[@pieromartinmendiburomerino7233]

its an amazing water rocket. I would like to knwo how much fins do i have to put in my rocket water, with 3 is better or maybe just with one?, maybe you can help me.

[@RaketfuedrocketsDeutschland]

+Piero Martin Mendiburo Merino Thank you a lot! Three fins are perfect, because one or two fins are not able to control the flight completely. You can also use four fins, but keep in mind that it's just extra weight you add to your rocket, which is never a good thing. :)

[@ayeshaashfaq6290]

Please tell me all the things that you use to make a water rocket

[@legendaussie465]

How did the pump nozzle fit to the hose

[@PankajPulikkul]

Could you please tell me what material you have used for making the fins? Thank You

[@gianvarona708]

So did he give you the list of materials yet? It’s been four years.

[@DutchProGamer]

Bro can I use bicycle tire valve instead of car tire valve?

[@MIG95374]

So should the car tire valve (6mm) be same as a bike pump normally or do i have to look for one?

[@MIG95374]

RaketfuedRockets so what other type of pump could I look for that will fit a car tire valve?

[@MIG95374]

RaketfuedRockets I'm an idiot, I can just get a car tire pump... Sigh. Sorry

[@Ibrahim-tt3fx]

can i attach a camera/gopro to the rocket

[@wfi2933]

Hi guys i have a problem.When i release the bottle from launcher the bottle doesn't fly up deviates left or right I think it's because of the center of gravity.Because the nozzle itself weighs and this moves the center of gravity upwards I haven't made a rocket yet, I'm just testing with a normal bottle how can I solve this problem ?

[@vesmirnepribuzenstvo3026]

Hi! if I put the barrel there, so I will prevent all the water from escaping? can this tee box be used for rockets that have interconnected PET bottles?

[@RaketfuedrocketsDeutschland]

Sorry, I don't understand what you mean. Can you explain it further?

[@ani6244]

could i use a 2 liter curvy coke bottle will i have the same results?

[@RaketfuedrocketsDeutschland]

sure, it´ll fly as well ;) The actual Altitude depends on the launchpressure which is usually lower for soft plastic bottles. The bigger diameter of the 2L coke bottle might also reduce the Altitude quite a bit.

[@ani6244]

@@RaketfuedrocketsDeutschland Thank you so muc

[@USWaterRockets]

Hi Julian, Very well made video, as usual. You do a great job editing and adding music to your tutorials. Congratulations on the nice job. There's one thing I thought might be an issue for someone in North America.... our hose couplings are too small to accept the bottle cap as you attached it here. I have never seen one that large before, so perhaps they are a specialty item someone could order online?

[@RaketfuedrocketsDeutschland]

USWaterRockets Hello USWR, thank you for your nice words. :) I made this tutorial together with Chris from our team, and it was a lot of work. It took us four shooting days and two editing days to make it. Tim is currently in China, so he wasn't able to help. In Germany, there are tap nut adaptors availbe with 1/2", 3/4" and 1" threads in every hardware store. You need a 1" thread to glue the bottle cap into it. Are there no 1" threaded tap nut adaptors available in the US? I'm sure you can buy them online. Greetings from Iceland Julian

[@USWaterRockets]

RaketfuedRockets Sadly, in the U.S. there is only one standard common size garden hose fitting used. This is a 3/4" diameter straight (non-tapered) thread with a pitch of 11.5 TPI. Oddly, this is incompatible with our standard for pipe threads, where 3/4" pipe thread has a pitch of 14TPI.

[@RaketfuedrocketsDeutschland]

USWaterRockets Mhm, thats good to know. It seems like this problem is pretty similar to getting PL Premium in Europe. :/

[@johndgibbons1]

I used a hair dryer to warm the threads of the pop (soda) bottle and then screw it to the quick connect hose adaptor. It is easily "tapped" to fit.

[@guillermof92]

I have a problem with the rockets and maybe you can help me. When I launch It , the rocket doesnt flight straight Up, It turns right very quickly. Do you know which could be the problem??? Thankss

[@RaketfuedrocketsDeutschland]

This problem is likely caused by the point of pressure and point of gravity of the rocket. Generally speaking, you have to attach the fins at the bottom of your rocket and make them large enough. And the top of the rocket should be a heavier than a typical bottle, so use a tennis ball or something like that.

[@rommelmatorres6263]

Can you tell me what materials needed pls

[@RaketfuedrocketsDeutschland]

For sure! Just check out the bill of materials in the video description. ;)

[@DoctorDiz]

What's a wessle?

[@DavidStefan-nz2en]

+Raketfued Rockets can you give me the bill of materials , because the website can't be accesed right now! Thanks!

[@RaketfuedrocketsDeutschland]

Hello David, unfortunately our website is currently only available in German. This is why you can't find the bill of materials. If you want, you can use the German list and use a translator. www.raketfuedrockets.com/index_htm_files/Materialliste_Einfache_WaRa.pdf We are very sorry and try to fix this problem as soon as possible. Greetings from the whole Team - Julian

[@DavidStefan-nz2en]

+Raketfued Rockets Thanks a lot! Anyways I know German so it is not a problem.

[@abbiem.6577]

Hey won’t the water go up in the hose as soon as the bottle’s flipped over?

[@RaketfuedrocketsDeutschland]

That's why we suggest raising a part of the hose above the water line in the rocket. ;)

[@abbiem.6577]

Raketfued Rockets thanks for the reply :)problem solved. The one last problem we have is that when we release the rocket it doesn’t fly straight upwards, instead it flies sidewards.

[@RaketfuedrocketsDeutschland]

That's a pretty common problem. You can try to change the launch pressure or to optimize the center of gravity of your rocket. Do you have a tennis ball attached on top of the rocket?

[@abbiem.6577]

Raketfued Rockets we just tried to mimick the weight of the tennis ball.

[@thapelonare9930]

Coleen Mape the tennis ball was for a nosecone not weight

[@davidxiao9175]

Pretty high.

[@ioguitarix]

hey i tried to build one of these but there are some leaks where The water and the air get through how can I fix this??

[@RaketfuedrocketsDeutschland]

+ioguitarix Sorry, but we can't help you without further information. :/ Please give us more details about which parts of your rocket are leaking. Thank you

[@ioguitarix]

+RaketfuedRockets it leaks through the threads of the gardena adapters

[@ioguitarix]

+RaketfuedRockets it also leaks through the nozzle's twisiting for the bottle

[@RaketfuedrocketsDeutschland]

ioguitarix Did you remove the seal from the tap nut adapter before you glued the bottle cap in?

[@ioguitarix]

+RaketfuedRockets yes I did. I tried fixing it with tape Which initially worked but then it started to Leak through the release mechanism
