did it just fart?

[AlexLabratories]

Good Job! I realy like the video and cool rocket

[turkville]

[electronics740]

that is amazing

[FuzorDragon480]

Homemade mortar XD

[29Ottomatic]

extreame lawn darts lol

[minibikerider1]

lol you can find the rocket point first lol

[luiscosta1992]

it sounded like a fart hahaha

[icef1sh]

cute



[pixelpatter01]

That is actually a mortar, not a rocket. Rockets gain speed after leaving the ground, a mortar will be going as fast as it can, just as it leaves the tube.

To get more range,fit a tube or rod inside the launching tube so the air will be pushing on it, not empty space after the valve opens. As it operates now, the most energetic compressed air wastes it's energy filling the empty tube before it starts building enough pressure to move the 'rocket'. Try a glow stick on the rocket at night.

@pixelpatter01 Thats a great idea - thanks! So basically design a "rocket" that slips on the inside of the launch tube instead of sitting on the outside? I think that is what you are saying. I could see that working really well. I'll try the glow stick as well. Thanks.

shoot it at some one



[purpl3guy]

What was that, 0:43!

[MrDeathray99]

you dont want to put your hand in front of this it goes about 250-300 kmph

155-190mph it would leave and hole in your hand

[fordyrox]

Lol, you gotta love the sound it makes when it hits the ground :)

how much psi do you think you can squeeze out of pvc before it gets dangerous?

[MajorJava]

I'd have to look at what schedule rating there is on the PVC. All PVC is rated to a certain PSI rating which by design, you arn't suppose to exceed. Its pretty high if I remember right - but from my testing, it wasn't really more PSI that helped. Because once you started getting higher, the sprinkler valve didn't seem to operate as well. If we could use some sort of quick-dump valve, or even we thought about a manual ball valve that we could manually open quickly, it might help.

[lilmarine93]

@MajorJava your better off using a sprinkler valve instead of a manual valve as it will be hard to open fast enough

[dvnvaughan]

@MajorJava use plastic pressure disks 

[thunderbolt881]

@idusclothing 120psi is when it gets dangerous,and i do mine at 120 psi and never had it explode on me!!

[Pizzapie500]

Awesome! if you want more height, modify your sprinkler valve.

[perisville]

sick!!! i need to do one for my sons project cheers

[MrJED698]

F(*^ would hate to be under that when it comes down

[MrNinjac0w]

better then mikes

[MajorJava]

@MrNinjac0w Yeah, I didn't make mine magazine-approved safe. I used an air compressor instead of a lower powered tire pump and I used plastic rocket bodies instead of paper. I tried paper at first but quickly got really tired of uncrumpling them so I went with a light-weight thin PVC for the rocket body. I want to add a parachute deployment next.

[DoesItGoBang69]

@MajorJava Nice idea!

[dylankunaikennedy123]

sounds like a saxaphone on 1st launch



[TheSquiglyProduction]

u should have gotten a target

[pudresful]

thats so !"#¤%/(%¤# funny!!!!!!!! I can watc this ower 1000 times and I laugtht allways

[mozeus5]

That's a kewl setup!

[blackspy13]

Lmao!!!

[samnoueilaty]

awesome! id did mine like this: i bought a 10 ft long pipe cut it in half and put a butterfly vale wher i cut it, then i put a stem valve at one end and sealed the open end then i pressurized it and put the rocket inside the other end. work pretty well

[Danger9584]

cool.

[hulkkike]

nice n simple

[rslane32]

what sizes are the tube and rocket? are they both pvc? how did you put the valve stem on? is that a standard pvc piece?

[jimmy258r]

Awesome!
