Materials Needed

24 oz. Mt. Dew bottle, empty and dry
pezzo igniter, you can find one in a disposable grill lighter, those long nosed ones for the stupider people out there
2 thumb tacks
2 rolls of 1 inch duct tape (just so you have enough for those patch jobs that will happen around the area of the thumb tacks or other things in the bottle. and it will depend on how much tape is in a roll.)( sorry guys it is inevitable there will be some patch work and the like.)
1 Bic round stick med/moy pen tube (do with the rest as you see fit. personaly i would make the actual pen into another missile)
those sticks off of those rock candies every one loves so much. put a 1/4 inch of duct tape around the bottum of the stick for a nice tight fit into the pen tube. (give or take an 1/8 of an inch sorry i didnt get the exact messurements for the end tape.)
1 good sharp knife
good file (may not need)
drill with a bit about or a little bigger than the pen (if its too small use the file to to make it bigger. yes this may take a while to do, but i did it and it was worth it.)
wire strippers
cheap hairspray or other flammable aresol (WD-40 and Carb cleaner are NOT recomended, they will ***t the bottle fast.)(and neither is a butane and hairspray mix. that makes BIG BOOM and can cause sever burns. i got away lucky with only a few small 1st degree burns.)
optional- the silver metal thing on the end of the lighter (it just adds to the affect. or wat ever color of thing yours happens ot be. but trust me it looks better with the thing over the ugly white pen.)

Assembly of the gun

1) drill a hole in the exact or as close to the exact center( the closer the better)
2) if need be use your file and size the hole so that the pen barely fits into it. (every so often check to see if its close to the right size. this will save you tape for the other things it will be used for.)
3) in what ever way you see fit, tape the pen as securely as possible into the bottum of the bottle. be sure that you have as tight of a seal as possible. and yes i realize that it will not ever happen that any one will make it completely air tight.
4) take your lighter and take it apart so that the little white thing with with a brass looking thing sticking out the back, and a black thing out of the front.
5) take your wire strippers and cut the wire in half
6) strip the last 1/4 inch of wire covering off of the end of the two wires.
7) take the second half of the wire and wrap it around the brass looking thing so that you get a spark between the two different wires.
8) now take some tape and secure the second half of the wire to the brass thing so it does not move at all
9) take the other ends of wires and wrap them around the thumb tacks to test to see if your wiring job was done right. (if not keep trying till you get it right)
10) once you have the testing of the spark done take the wires off of the thumb tacks and push the tacks through so there is about an 1/8 inch or less distance between them ( but not touching!!!) or you can play around with it till you get a nice blue spark. (keep in mind that this will weaken the structure of the gun. which means more patching jobs)
11) once the desired distance for spark is reached, attach and secure the wires to the tacks and the tacks to the bottle with tape until there is very very little air getting out.

Assemble of the rockets

1) take your rock candy stick (presuming you have already eaten the candy) and put a layer of duct tape on it.
2) repeate this prosses until you have the right amount on (this may take a while seeing as its just trial and error work now)
3) once the right amount of tape on....test it out!


it may take some time to get the right fuel/air ratio down, but i found that this type of bottle works the best for this. you will get about 2-3 shots before you need to let the gun sit and air out. but it works fanominaly if done right. i put a nice dent into the side of a 24 oz Monster can with it from almost 20 feet! insane!
after i get some time to work out the kinks ill post what i have found efective for pointed missiles.


if any one has any modifications that they would like me to add to the thread send me a PM and i will get your suggestions put in or you could just put them in your self.
and if any one has any ideas on how i could improve my design i am open to suggestions.


thanx

Total shit, your ratio is terrible.
Try a pill bottle instead.

that would be nice. but this one i didnt design to destroy things, and last i checked it was illegal to destroy things by any means and weather you own them or not. but thats just me. and this one is just for shits and giggles, thats all. you kno a party favor type thing.

did you look at that site?
look at all the different guns you can get

twenglish1
December 11th, 2008, 09:25 PM
yah i did they have some pretty sweet stuff, i need to get one of those rifled barrels. but i'm telling you it would be alot cheaper to build a gun yourself and more fun(well for me anyways)

termanat252
December 11th, 2008, 09:30 PM
yeah but i dont have the time to build my own
i would rather have the one im ordering too

twenglish1
December 11th, 2008, 09:31 PM

the cumbustion with a tenis ball barrel and then im getting a 2 inch rifled barrel and a bag of those bouncy balls. i only have 3 words to discribe them to you: "FLUBBER FROM HELL!!!"
they gonna go every where

haha cool i have never shot a bouncy ball out of my gun, but i shot a moltov cocktail once, it was fucking awesome everything was on fire. i duck taped it to a wooden pole put tape around the pole so it fit tighly in the barrel and i lit the moltov and shot it. it flew about 50 yards and hit the ground and exploded into a huge fire ball.

wow how big is your barrel and wat kinda bottle did you use??? i aint gonna do that

twenglish1
December 11th, 2008, 10:36 PM
my barrel is about 8 feet long and about 2-1/2 inches wide. for the Molotov i used a glass beer bottle filled with gasoline and an old rag coming out of it as a fuse. the pole the bottle was taped to was what made it fire from the cannon, the pole was wrapped in tape so it fit really tightly in the barrel. oh you saw the pics right that i posted earlier??

termanat252
December 11th, 2008, 10:48 PM
yeah i did you should post a pic of your different projectiles
if ya would plz.

twenglish1
December 11th, 2008, 10:54 PM
i will tomorrow or something its really late here and i have to rebuild some of them cause one exploded and the other caught on fire. the only projectiles i used besides a potato and random objects that fit in the barrel, i used a Molotov and a pipe bomb. both worked great but the pipe bomb didn't go as far cause it was heavier. i used a one foot fuse for the pipe bomb so it would have time to fly before it exploded and if it misfired i would be able to get away from it

termanat252
December 11th, 2008, 10:59 PM
yeah you should try out an AN-AP bomb in a tenis ball for me cause itll be awhile before i get mine back or a new one made or bought. so yeah. and that would be awsome if you did get some picks of your missiles.

twenglish1
December 11th, 2008, 11:05 PM
i still have the designs but the missiles are in about 1000+ pieces somewhere and i would use ap-an but it takes forever to make enough for a nice sized explosion and i will try to dig up my designs too for the missiles

termanat252
December 11th, 2008, 11:07 PM
if ya ever find them i would realy appreciate it if you put them on here or sent them to me via PM. but other wise that would be great.

twenglish1
December 11th, 2008, 11:11 PM
ok i will look for them and i will print them in PDF format cause they are in AutoCAD, but if you have AutoCAD i can just send you the design files

termanat252
December 11th, 2008, 11:13 PM
just explain what an AutoCAD is please. and thanx so much it will help me out alot at parties and the like.

One of mine is posted already.

December 11th, 2008, 11:16 PM
AutoCAD is a computer program used to design...uhh...just about anything. i used it to draw up my missiles before i built them and i used it to draw up some other stuff i am currently working on. and i don't know how it will help you out at parties

termanat252
December 11th, 2008, 11:22 PM
just by scaring the fuck out of drunk ass holes who are throwing the parties and at the birthday parties for my little cousins who will just love to see things go flying out into oblivion. but i prolly dont have AutoCAD so youll prolly have to put them in PDF fromat if you can.

twenglish1
December 11th, 2008, 11:25 PM
yah sure no problem, but like i said i need to find them first

termanat252
December 11th, 2008, 11:27 PM
