Intro: Cheap Cannon

this is a cheap cannon made with a 1 liter drinking bottle a barrel i used a mini lacrosses stix shaft

and some tape and siscors

Step 1: First Step

Take your bottle and drill a small hole in the bottom. Make sure it is big enough for a flame to go in.

Step 2: Step 2

take your barrel and attach it to the bottle using duct tape. Make sure its snug and cant move.

Step 3: Step Three

Take your ammo and put it down the barrel (cotton balls are fun). Then spray some flamable of your choice into the little hole, wipe off the liquid that gets on the outside.THis will cause the plastic to catch on fire. Then lite it and bam your 1 minute gun.

    you may want to add a piezo from a disposable lighter as an ignition source, as you just press a button and make a spark instead of sticking a match in the end and blowing ur hand off. also, wot flammable would u recommend?

    plz reply.

    I wouldnt use a soda bottle I'd use a Metal Thermos or something with a hole in and a Electronic Bbq lighter instead of a flame Alot more safe and I'd use hairspray and things like Popcorn Kernals hehe

    It'd really have if you had specified what to use for the barrel, flammable substance and ammunition.

    I have this feeling that this isn't too safe since you're using a soda bottle as your blasting chamber and all you did was tape it onto a pipe.... Another item of interest: "screw you i will spelll how i want to.", not instructable friendly talk. Even though Dr. No could have pointed out the grammer/spelling abit nicer, that isn't any excuse for you to make a poorly written instructable that you seem to have no intention to fix.

    When I read your instructable, it hadn't been "fixed" (and yes, I clicked the refresh button before posting my comment). Technically, no it isn't "fixed". Any good reader will realize that you still made errors in your instructable (not including the intro). You may also want to include a warning about how this cannon is dangerous somewhere in your intro.

    That much is true, but unless you post a disclaimer, you can be sued for any damage this project causes.

    It is better to warn and be safe, then not have warned and be sorry.

    you could step really fast on the bottle and it'll launch, but i like your idea better.

    These do work. I made two 'barrels' from steel tubes I found in a dump-master. From work I took home sturdy 1 liter plastic bottles that were to be thrown out and cut a little hole in the bottom for a piezo spark gun. One of the barrels presses nicely onto the lid of a bottle, the other barrel has a smaller diameter and had to be duct-taped to it's lid. For ammunition I like to use gum nuts from eucalyptus trees, wrapped in a piece of tissue paper which acts as a sabot and provides a good gas seal. This tissue also allows the nut to slip down the barrel smoothly but then falls away after leaving the barrel. Cutting a cardboard 'X' sabot also allowed me to shoot irregularly shaped little stones and marbles. Load the barrel, squirt some ethanol into the mouth of the bottle, screw the barrel onto the bottle, aim, insert piezo spark gun into it's firing hole and bang. I too rather carelessly blew a hole in my wall with a gum nut and will have to fix it up. A puff of butane can also be used as a propellant.
