Water Rocket Launcher

[extraflyer1]

it looks like a usb cable

[smellycatpoop]

Thanks for showing the launch pad!

[parkourkid4ever]

i used the same concept but mine's handheld haha its freaky.

the weird thing is i also used a fresca bottle

[bmwguy11]

i have a similar setup :D nice adjustments tho

[soccerboy926]

that bull shit

first off you need "o" rings to seal it.. wow i wont even explain.. but mine launches so high you struggle to see it

secondly your rocket is built like shit

you need something called a skirt and you attack fins to that

then you need a cap that holds a parachute

and you need a cone on top of the cap to make it more aerodynamic

cool

[fockofpompi]

fuck it dude its a bicycle pump attached to a bottle

[microsoftandryson]

your bottle water is spill out...

but nice launcher...

u really involve urself in this activity?

i wonder if there's launching rocket competition at ur country...

nice..lol

[ZenterX]

waste of time

[hobiehippo]

if he sounded any more excited i may stay awake

[xxxitaymoonxxx]

hey can you make a tuturial of how to make the launcher its hard to saw how did you build that

[weirdcharmedp3]

hey good video !! mmm can you message me the list of ALL the materials please? thanks

[benattewell]

Perhaps you could create a design which allows you to attach the rocket wthout spilling any water? Maybe a removable base?

[kingstonr312]

How about a small hole Just to fit on the pipe?

[warthur67]

very instructive thanks

[psycopyro001]

instead of putting all that work into pumping it up to pressure you could use an air copressor which would build the pressuse alot quicker with the pull on a trigger

[gansta246]

can u message me ALL the steps it took u to make the platfom and launcher

[gansta246]

[tomisdabomb02]

thats a nice sistom you have set up verry good work!!!!!!!!!!

[Pyromaniac002]

thanks. theres lots of links on ow to make the rocket but hardly ne to make the launcher. that helps alot!

I have since modified the launcher by replacing the thin launch tube with 1/2" PVC piping. This fits nicely into the nozzle and keeps the rocket going straight before the fins start working. Stability is a problem and I will be modifying it as per the design provided by Kamiel Martinet. The launcher in my video prevents you from putting fins behind the rocket, and they have to go way back to get stability (getting the center of pressure well behind the center of gravity).

[gk123434534]

Try adding a nose weight instead. It's usually the easiest way to achieve stability.

[Cryogenius]

Thats exactly right gk, and yes I did that too (five penny's worth of weight) and it helped. However, by my calculations that extra weight reduced the height of the launch by about 25 feet (more than 10%), so I try to optimize fins vs nose weight. You are right that nose weight is easier though.

Sweet!

ive been browsing forevr to find how to make the launcher

[Cryogenius]

oh yeah!

[Demiana121]

Awesome video, dad! I think the next project should be something like a pumpkin-launching trebuche hehe.
