Used to watch your videos as a kid, love the nostalgia
we just built one and it's amazing how well this works.
i think this is the best and the simplest vid on youtube for making a water rocket+launcher !
nice work!
We built one of these soon after seeing it on TV. Easy to assemble. (Give the glue a day to dry!) We experimented with different amounts of water and different pressures. We tend to fill it about 1/3 full. 30-60 psi worked just fine. I read somewhere that the bottles will fail around 120 lbs. (Haven't tried that!)
Simple, effective, clearly explained and safe, it's a great project !
Thanks, Doc. I hope that people click on your channel and see your amazing, unworldly ramp-walkers!
Totally just built this and it works like a charm thanks.
Great explanation, very good work
Great introduction!
I love the technical term " Springy Thing ". LOL
Great ideas! thanks for sharing this.
My brother built one, its awesome! :D great video!
this is freaking FUN!
It will work with any bottle that just slides onto the pipe. If the opening of the bottle is not matched, then it will not seal. Making a small bump on the plastic pipe is what holds the pressure in.
smart man
Thank you Very, Very much! I have been looking for launch ways to launch it without losing pressure. Thank you véry much :D
It does have all the links at the web page, but I did add linked annotations.
Mine works great!!thanks!!
Gracias, haré un cohete similar para mi bebita, espero que se divierta tanto como espero. Thanks for this video.
Some people have sanded the pipe to a slightly narrower diameter so the bottles just slide on perfectly. In North America we don't have to do that, but measurements are slightly different in other places.
@afiq8219 Actually, I think conduit will work if it is the right size to fit in the bottle. We don't come anywhere close to the pressure that would rupture the pipe.
Slater
@afiq8219 Yes, whatever works to get the air pressure inside the pump.
@TRTtherocketthing As I say in the video, years ago Australian Ian Clark put up the idea to use zip ties to hold/release the bottles. I enjoyed your videos.
Slater
Great idea
@afiq8219 Yes, but I expect there would be a lot of experimenting to actually get it to fly well.
Very Nice.I am happy that these actives are still alive. I see many kids playing
Video Games,but these video games don't give you knowledge.These experiments will give you knowledge and you will be able to make your new inventions, in future.
sciencetoymaker I want to ask you that can i reuse this launcher.I mean i will shoot the bottle and then I will fill it again ,can i use it again?
Hi, quick question(: When pumping my bike pump, the water from my soda bottle began to leak a lot. Do you know what I can do to stop the leak, I did everything you did in your video though. Should I make the indent in the PVC pipe larger?
@TSK213 That and more at the sciencetoymaker website, linked in the text area.
Slater
About 30cm high and 10 wide. You don't have to use 2 liter--any size will work as long as the spout just fits onto the pipe. I like your hot air balloon flying video.
Slater
What size PVC pipe do you use to hold to zip ties in place?
@cdltpx Yes, there is another website called antigravityresearch that uses smaller diameter openings to stretch out the power.
Slater
@afiq8219 I'm puzzled.Auto part stores might not be common, but there are automobiles in Malaysia. Find a person who fixes tires.
It could be a number of things. The zip ties have to be adjusted (with the pipe clamp) to hold the bottle to the bump. The bump in the pipe has to be symmetrical. There could be a crack in the stem of the bottle.It usually comes down to pressurizing a bottle and looking very closely at.what's going on.
Slater
Hmmm, which measurement do you want? Width? Length? Spout opening?
Slater
Hi, just wondering, would it work with any other types of bottles???
i made one for school to dose the whole state make one?
Hi! Can you please help me. You see I've got a problem - I can't find the pvc pipe with this width to put it into the bottle - the ones at the stores are too big. What other pipe can I use?
Nice
nice tutorial :)
very nice video... 5 stars
@sciencetoymaker nice ideas I subscribed
you should put part 2 link using annotations at end of video
@101smallface Yes, it can be short. I make it long because I'm afraid it will hit someone on the way up. Kids are impulsive, like to get wet, and they move fast.
Slater
thank u
Kool.
I have rwo problem,
1)some bottles cant fit easily in to the tube, once it is fit, it cant blast off when i pull down the string
2)bottles which fit easily in the tube, leak lots of water,
anyone know the solution?
i use to build my own water rocket to show to my kids how it works but i dont use launcher instead i use only ball valve and i only hold it pointing upward then open the valve and release it,but some how i want to make also my own launcher.
you can get it from a inner tube from the tire of a bike
what size is the tube that goes over the zip ties actually what are the sizes of all the tubes
+Tyler McBride The pipe i used was 49 mm OD and 41 mm ID
Didn't see that. Thank you
All the details are linked in the video description.
@devaroo5t I think you should have an adult help you with it.
However it would create an issue that springs because of how thin they generally are would be too loose themselves. And using a larger spring would only make it harder to use. Sorry, I have a bit of firing mechanism knowledge.
verrygood
Good
you need to list the diameters of piping needed.
nice rocket bess bapok
Not sure if "I" got the idea from MYTHBUSTERS Tie wrap mechanism..for releasing the bottles or from ..YOU..sciencetoymaker ... Very good ...if the credit is yours ..Can find any other better..TRT "the recycled toy" is hooked on ROCKETS
safe? what happen if we shoot it on a airplane?
like
im 11 now that was when I was born now 2019 it was 2009
1,63 for such a long pipe???????
its like 15 here.
Yes, you reuse it. I have launched thousands and never had one wear out. You reuse the bottles over and over, too.
Slater
it would be more easy if there was a diagram
@olmann1989 .....
Your comment is not so impressive.....
No one likes it...
