i used a m&m mini bottle and it doesn't seem to work does anyone know if there is a problem

[danieljw]

does the back pop open cuz it dosent close very good

[firefighter1333]

well maby , cuz its such a small chamber, u flouded the chamber by sprayin/pourin in to much fuel.

That is absolutely disgusting.

[macboy98]

can we use perfume instead of hairspray?

[danjo62]

most perfume isnt flammable though

[knex luver234]

heres mine, its the cricket

[Laxdan37]

Pls do me a favor: anybody who does this... Do not use a 2 liter bottle instead of the pill bottle... Thank you

[raynman217]

LOL, Does this request stem from personal experience?

[ThePyroManiac]

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.

[punkhead58]

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.

[ThePyroManiac]

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.

[Laxdan37]

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.

[whiteboyninja]

instead of a bbq igniter, can you use the sparky end of one of those long lighters(an empty on)?

[thebair]

yes

[11richie21]

open that lighter up and you will find the same igniter

[whiteboyninja]

ahh thnx

[wwed]

great for class! awsome

[BluePhenox]

Anyone know how to do step 4???

[Kwitmeh3]

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)

[nutsandbolts_64]

Cool. but uh....... wats my ignition if i dont hav a BBQ lighter?

[MechEngineerMike]

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 !

[Paper Man]

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

[A_squared]

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.

[sensor15]

You did really good for your first instructable. Keep it up!

[A_squared]

Thanks.

[chi chi chippy]

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

[A_squared]

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.

[Kweltan]

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!!

[sk8rd00d131]

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

[tecno geek]

i did it, go to this link:

[blizz86]

already done on techblog.

[A_squared]

Yepper

[flaktveit]

eh...okay. So that`s how it`s done...

[freeballinjoey92]

i tried it but the problem i had was that the pill bottle was too small and when i sprayed the hairspray it would condense and wouldnt ignite. so i used a baby formulda thingie(a bit bigger) and it worked alrite

[zace123]

some picts of the built gun and the steps would be good to add peace out

[Loveofchaos]

I just saw that video that u have there. it is a good idea, but it seems to me that if you could get an airsoft bb in there that it would work much better. ill try to build one, i know where theres a gluestick my brother wont miss lol
