Ultra-simple, improvised camping stove

Ultra-simple, improvised camping stove
The simplest ideas are usually the best eh?

I have been experimenting with various designs of improvised camping stove for some time now. They have varied from a simple open cup of burning fuel to highly intricate vapour pressure devices that take hours to build.

This is my latest favourite, it is a combination of two established types of stove. A chimney stove and a low pressure side-burner. It takes about three minutes to make and so can be constructed as and when you want to use it.

This design also has the advantage that it will run on pretty much any flammable liquid you put in it. I have used methylated spirits, rubbing alcohol, xylene, white spirit and petrol.

This brings up an important safety issue though, anything other than an alcohol type fuel is inherantly a lot more dangerous. Pure hydrocarbon fuels like xylene and petrol are toxic, dirty (they make a real mess of your pan!), smelly, potentially explosive and can't be put out using water. An alcohol fire can be extinguished by upending your pot of water over it if things get out of control (don't believe me? Try it.)

For more info on improvised stoves have a look at the site that inspired me to try experimenting: zenstoves

Step 1Build your stove

Build your stove
Ok. To do this you will need:
1) Empty 330ml soft drinks can (size not that important)
2) Can opener.
3) Pointy thing (bradawl, nail, tentpeg, sharpened stick)

So essentially an empty drinks can and a swiss army knife.

First remove the top of the can using your can opener, be careful not to damage the rim too much.

It would appear that the rim is an important part of this design. Without it, the aluminium of the can might start to melt and crumple from the heat. Some can openers slice the entire top off, these are not suitable (see picture below for what the completed stove should look like).

Now punch eight, equally spaced holes through the side of the can about 1" up from the base. The holes should be roughly the diameter as the awl tool on a swiss army knife or a round steel tent-peg. (again, size isn't all that critical, spacing is more important)

Punch another ring of eight holes round the angled part of the can just below the top rim.

Punch a third ring of eight holes through the side of the can just below the angled part, arrange them so they fall inbetween the upper row of holes.

Your stove is now complete!

do you think I could use a big can, you know, the ones that have grapefruit in them sometimes, but use wood fuel instead? Because I doubt my fussy mum would trust me with flammable substances :D

hey fellow instructables,
nice idea almost every stove builder is trying.
BUT:Don't want to disappoint those who like the simplicity of this design, but this one is REALLY DANGEROUS ! It can harm you and your surrounding because of the complexity of diameter of the holes and heat output which is uncontrolable. In field testing hobo and alcohol stoves for more than 30 years we found out that the cans may collapse without warning due to too high temps causing spilling, spitting and dragonfire like effect having burning splashes several feet around the fire place leading to severe burnings, injuries and even death if fire is not extinguishable (plastic, oil etc.)

Please do check out all the noticeable sites with proven designs and security advices. Keep on instructing, folks!

A little too ultrasimple...
The thin aluminum's survival depends upon the boiling alcohol. That means a critical moment occurs when all the alcohol has vaporized but is still burning. Crash!

If you're concerned about crushing the can when punching holes in it (and you've actually got your workshop), just fill it with water and freeze. Punch the holes while it is still hard frozen.... ta-dah... also, although it may be wobbly, 4 empty soda cans can support the weight of a car (if it is settled on them properly and there are no dents in the cans). Awesome ible... I will definitely be trying this one soon.

so I tried out a stove using this design tonight and it worked well. i realized that i needed to let the alcohol burn for 30 seconds to a minute to get a good flame. now that i've been successful at making a cup of tea on a humid massachusetts night any ideas for things i could cook on this stove? soup? rice? id love some feedback with what works and what doesn't.

check out Backpack Gourmet. It has a whole bunch of recipes for traveling light. FYI, you need to dehydrate them but all you need is water on the trail! Happy camping.

thanks a lot!!

can i use nailpolish remover as fuel?
Jul 7, 2011. 10:33 AMacoleman3 says:
ohhhhh yes. its acetone which is as flammable as methanol. problem is, its more expensive. i can get 4L of methanol (1 gal) for $13-14 at my diy and it lasts me a month.

this is a great stove if i make a few of theese i should be able to make a good
grill

this almost burned down my house

BE CAREFUL!!!!
Dec 31, 2010. 1:43 PMrangerman2889 says:
Would it be possible to move the holes on the bottom up another inch without compromising functionality? If so, it would greatly increase the fuel capacity enough to also house a media to help hold it as others have mentioned. Great build though!

would energy drinks (red bull etc) work too because caffeine is flammable
or would it burn out too fast
Jun 2, 2010. 8:59 AMguillaumedem says:
 well, one can of red bull contains like 80mg of caffeine. So I guess it won't (:
And btw, is caffeine even flamable? :)
R22 Harmful if swalowed
S2 keap out of reach of children
So it isn't  flamable

Is Energy Drinks Flammable?

May 1, 2010. 2:24 AMsilver362 says:
dunno thats what im askin
Jun 12, 2011. 1:21 PMMeuryn says:
Nope, energy drinks aren't flammable, caffeine isn't flammable either - not sure where you got that from?! You might be thinking of using high alcohol content drinks, which can be flammable. Think of a liquor over 40-50% alcohol and that should work; but it is far cheaper to just burn meths or petrol.
Oct 15, 2009. 2:50 PMTarzanJr says:
The 12 ounce energy drink cans heat faster cause it focuses the heat toa more concentrated area plus the flames need more oxygen so the tallcan give more room for oxygen to enter the can and the smoke or whateveremition comes from the fuel out.
May 2, 2010. 6:12 AMchibiwind says:
the energy drink cans where im from are quite small, and still im pretty sure size wouldn't draw in more oxygen i think the size of the holes would affect that, a lrager can would hold more oxygen if that is what you meant
May 14, 2009. 5:04 PMosmonde says:
another idea would be to make one out of an aluminum can, it doesnt have the slanted top but it would be way stronger so you could have a heavier load and be more heat resistant so you dont have to worry as much about it getting soft or melting
May 13, 2009. 1:50 PMVanWinn says:
I made a stove similar to this and was having trouble getting the stove to produce a strong flame. The reason was because not enough heat was staying with the stove to keep the denatured alcohol vaporized. I solved this problem by adding 2 copper "heat Pipes" to the top of the stove. I got some 1/8 copper tubing measured it and bent it into a "U" shape. I then drilled 2 properly spaced holes and inserted the copper tubing (open side down) into the top of the stove. The pipes should be just short of the bottom of the stove. This made a HUGE difference! I could now here the alcohol boiling in the can.

having trouble... my stove works fine until I add a pot to it, it works for about 5 seconds and then one by one the burners go out. followed instructions as well as I could. using: Arizona Tea Can 91% Isoporyl Alcohol Any suggestions welcome, thanks.
Dec 26, 2008. 9:54 PMsirjamesalot77 says:
This design works really well. I tried it and put it on youtube, it's the second one:

Apr 2, 2009. 2:08 PMphoenixjen says:
This stove looks good sitting on top of the can but can you put a can or something you are heating up on the stove? Why is is so dented?
Dec 31, 2008. 4:02 PMch0wderdood says:
and what was your fuel for both cans?
Dec 31, 2008. 4:02 PMch0wderdood says:
where or how did u make that pot stand and the stand for the stove?
Mar 17, 2009. 8:21 AMbylerfamily says:
Would 91% rubbing alcohol work in this stove?
Apr 10, 2008. 9:39 AMdavidp says:
That's a great idea. I'm going to try it myself. Would an 8-ounce drink can work as well (don't know the metric equivalent)? Seems it would be more stable, not being as tall. Just a thought.
Mar 11, 2009. 4:22 PMbylerfamily says:
Yes it would work.
Feb 5, 2009. 1:37 PMdavid_ says:
Do you fill the can with anything other than fuel (alcohol) ie an absorbant material? I know many commercial and home-build designs use something like this to both extend burn time and avoid that flash-back you talk about. I believe I have seen kitty litter being used. I guess it doesn't burn. I think i have also seen plaster of paris being used since it can be poured in wet and when dry absorbs the alcohol very well and will not burn.
Feb 16, 2009. 4:21 PMvoltagedude says:
You should try fiber glass!! it works great. you can find some in your attic or basement.
Feb 5, 2009. 2:43 PMThe Real Dave says:
This is a great project and looks reli cool, but can I ask, whats wrong with a good old fashioned campfire :D
Feb 5, 2009. 5:32 AMHawk20 says:
I have followed alcohol stove designs for years and never found one worth the time to try. Finally an elegantly simple design that works. Thanks!
Jan 18, 2009. 12:42 PMwoody558 says:
one idea is to use a hole puncher to make the holes
Jan 15, 2009. 11:12 AMwoody558 says:
This stove doesn't work very well. Te pot ALWAYS smuthers the fire.
My favorite stove is this one:
