Step 1: The gun

Picture of the gun
It's pretty obvious.
you need...
tiny advil pill bottle
--2 tacks
-pen tube
-bbq ignighter(inside a utility lighter)
-electric tape

Step 2: Build

Picture of Build
Cut the end off the pill bottle(the end without a cap).Stick in the two tacks into the bottle and make it so they almost touck(like a 3mm gap). Take a wired up ignighter and strip the ends and wrap them around each steel part of the tack and push down(if you dont know how to wire the ignighter too bad!).Tape the ignighter down to the bottle(make shure you can still press the botton).Wrap tape to the end of the pen tube so it snugly fits into the cut end of the bottle.Test for a good spark(rewire if it wont spark).

Put a bit of potato in the pen tube. spray a bit of hair spray in the screw end and put on the cap.

fire and enjoy

Ps. this is my 1st instructable tell me what u think.

Step 3: Original

Step 4: Nothing

I was just wondering, would the pill bottle start melting due to the fact that things are exploding in it?

Damn, i was playing with it last night and it self destructed. Did you know you can make a flamethrower from this and the fuel can? It's simple. spray a shot of fuel in the cannon, dont close the end, then ignite it. Then spray deodorant across the flames coming from the bottle.

Pls do me a favor: anybody who does this... Do not use a 2 liter bottle instead of the pill bottle... Thank you
LOL, Does this request stem from personal experience?
According to the diagram the ammunition/piece of potato is to the front of the barrel. If you'd like to gain more distance you can push it further down the barrel. Just a tip.
Not necessarily. The farther it is pushed back, the more energy that is needed to push it down the barrel, thus the less energy that is left to project it. However, if you put it in the very front of the barrel, it would be very inaccurate. You simply have experiment and find a good place to push the projectile that's a good balance between distance and accuracy, it all depends on the shape and weight of the object.
You're right, you may waste energy pushing it all the way down, but that would be your own fault for using a projectile that would not leave the barrel cleanly. I'll admit I don't use a normal mini spud gun a lot, but in my experience with advanced, scale spud guns so far it's best pushing it all the way down.
Or just use airsoft pellets, and put one of the stoppers that's normally in an airsoft gun, this way u don't need a ramrod. I did this, put a pistol grip onbit, and made it a shotty attachment for my panther a15.
instead of a bbq igniter, can you use the sparky end of one of those long lighters(an empty on)?
open that lighter up and you will find the same igniter

ahh thnx

Anyone know how to do step 4???
i know, stare at the screen and the ~~dots~~ periods for at least 3 ~~minuates~~ ~~manuaters~~ ~~minutse~~ minutes on the ~~fourh~~ fourth step then you ~~cant~~ can do whatever (rob a bank,steal a car whit the spud gun)
Cool. but uh....... wats my ignition if i dont hav a BBQ lighter?
if you use too small of a bottle the fuel-oxygen ratio will be VERY hard to get right. It makes a biger boom and is more reliable to use bigger bottles. If you want to see a manly spitball cannon check out my instructible by clicking on my name !

Dont tease me but wat the hell is a spud gun???!!!!!!

A spud gun is a gun that egnights a small amount of fuel using a spark. This ignition causes a build in pressure that forces out a piece of potato in the guns barrel.

ok i made the gun but i cant get it to shoot can some1 help me i did do one thing different, instead of the tape around the barrel i drilled a hole and i glued around the edges would that be the problem? ill apreaciate the help

you most likely are just flooding the chamber with too much fuel. You may have you diodes too far apart. Or, you have too big/small of a blast chamber.

This is a great instructable (even if it wasnt your idea) i just finished making this mini spud gun and it worked perfectly. I used a Herron mini 25 capsule pack though, so there isnt alot of power but still it works well. Good Job!!

is there any way that you can fire it without the lighter igniter
