I made this back in 2013; except I made a few design changes like I remodeled the bbq lighter case to fit the mini cannon and re designed the trigger. I also found that heet ( a brand of gas-line anti-freeze) works a lot better than isopropyl alcohol.

I found that using a mini spray bottle full of alcohol instead of a cotton swab makes it easier to get the amount of fuel to air ratio correct
Where will we get that
u could probably get one from Walmart but I just found it lying around my house

It doesn't have high enough levels of alcohol so it won't ignite.

Ok I'm srry to burst all ur little bubles but one contrary to watnighthawklight said adding oven a miner amount to much fluid nomatter what u use for fuel it could still blow up I know because my little brother was killed when one blow up in hi hand oh and I've taken these kinds of weapons of inmates at my prion that have been used to kill people and are illegal nomatter what they shoot
I'm sorry your little brother was killed. However, as to the illegality issue. Illegal in prisons yes, by non-felons not incarcerated no.

Hey, im building this cannon but im using lighter fluid as the fuel for it.

The thing is that I cant get it to ignite. There's a spark and everything, but it just wont ignite. Ive tried using more fuel but still nothing happens.

But when I take the rear bolt out and light the cannon with another lighter.. BOOM!
A lot of fire

I dont know whats wrong... Can someone help?

Lighter fluid will not work because it doesn't vapourise to give an explosive air/fuel mixture. That's why alcohol, hair spray and ether are best.

Sounds like the fuel / o2 ratio is off....i.e. you need more air.

are you using 91% rubbing alcohol
you might be adding to much gas it also it is a bit harder to make lighter fluid ignite unless its a steady stream of gas
Sounds like the fuel:air mixture is way too high try using less fuel :)

You can't use butane in this, the chamber is too small. If you add more than 3% of the volume of the chamber worth of butane it won't have enough air to ignite.

I have a problem. Here's what happens when I use this:

1. Add rubbing alcohol (91%)

2. Click! Click! Click!

Sorry, I deleted my first reply because I thought you were commenting on another project. Can you see the spark in the chamber? If it's bright neon blue that means you have too much fuel. If not, you probably don't have enough fuel.

so i built mine, but it won't fire. i rewatched the video, the only alcohol i have in the house right now is 70% so i think that might be the problem....

what other fuels can be used in this?
Do you have to re-swab it every time?

DO you have tO register it as a firearm?
Do you have to register a potato gun? no.

*sigh* sad isn't it...
just melt the wax out
Thank you so much for this! I love shooting my cat with it xD
I used a pill bottle and nail polish remover instead, works just as good or better than the fuel resivior

Will it effect the explosion if you use 70% rubbing alcohol?
SteamOh3 years ago
Well, apparently this instructable has been up for a while, but i never saw it Dx
WOnderful piece of work. I finished building mine, but only got it to shoot once... i see from other comments that fuel to air ratio is a problem, but have no grasp whatsoever of how much alchohol to apply... Any advice on that part?

Thanks and awesome work
