Picture of Cool Little Miniature Stove!
I'll show you how to make a great little portable stove from stuff you probably have laying around your house! It's perfect for camping, backpacking, and power outages.

I am not the inventor of this stove, and there are far better designs out there (Penny Stove is the best!), but this pressure-based alcohol stove is by far the easiest to make.

Watch the video for an overview:

thanks, great instructable. Just a couple of questions:
1) I've seen in other instructions (don't think on instructables though) that you need to cover the filling holes with something like a penny, is that really necessary?
2) Maybe somebody knows, is there an equivalent for HEET in Germany?
In a nutshell, HEET, is one of many commercial names, for standard Isopropyl Alcohol. (sometimes called Dry-Gas.. You add it to Gasoline, during severe cold weather to collect water from the fuel tank, and carry it along to the engine, so it won't freeze in the gas line.) Denatured (Wood Alcohol), found in painting stores as a thinner, Sometimes found in Marine (boating) stores as cooking fuel. These can stoves are based on Alcohol fueled Marine stoves.. (which I don't see too many of anymore, but see the denatured alcohol still in camping & marine supply areas in retail stores.)
And to answer your first question: It prevents (somewhat) the burning trough the big filling-hole.
If you have one big hile, most of the pressure and thus vapor will exit there and you have one big flame coming out of your filling hole. But we want many evenly spaced flames on the rim, right? So block the filling-hole with something (Penny, Screw, Plug, Insulation, ...) and let the pressure exit the outer holes and generate a neat ring of fire.
Spell check :( Germany is german.
he meant germany. he was asking if in germany there is an equivelent for the "american made HEET".
I meant my comment :) (Danger inflammable (in germany)) should have been (in german)
oh...lol...sorry :) i guess i got cunfuzzled. hehe
Basically, keep your eyes open, and when you see any products (often cleaning) that say Danger Inflammable (in Germany :) ) you can just guess if it would burn well.
Otherwise, you can just buy rubbing alcohol (for disinfecting wounds, or cleaning stuff) and get one with the highest percentage alcohol possible (over 70% minimum)
yeahh, this is confusing. I think you need to rewrite part of this. Is the Fiberglass needed?
Anything that can serve as a wick.
you dont have to put any absorbent material inside the stove because i dont put anything like fiberglass or cotton in my stove but the fule and it works just fine you just have to heat the stove up first.
Some of the designs, have a strip made from the remainder of the can, that sits inside, from the rim at the bottom, and the underside of the top rim, leaving a chamber between the center & outside wall of the can. This acts ass a catalyst, carrying heat down from the top to the pool of alcohol at the bottom, promoting boiling. I've made a few with 2 bottom halfs, and most recently, scoring out the center of the top, just leaving a small lip inside. 2-oz. of alcohol is plenty for boiling 8-Oz. of water in about 3-5 minutes. Not as good on windy days, as the wind cools the aluminum, preventing the boiling inside.

I made one of these, and I boiled a cup of water in just a couple of minutes. I think you should at least double the number of jets if you want a faster burning and hotter stove. It looks like this one would make a good simmer stove. Maybe good to have one of each?
Your video isn't working, but it might just be my computer

Seen this a few years ago on YouTube ,now loads of variations, as Heet cannot be bought in the UK methylated spirits can be used.

I guess I'll be the first to say that cutting an aluminum can with a razor blade is a pain. I made the 20 rotations patiently with the razor blade and only managed to etch the can. I then took a dremel to it and in 1 pass the can was cut. I'm trying to figure out how to make a cleaner cut.
I usually make an ugly cut in the can with a razor blade about a cm above my line for my final cut. And then I do the rest of the actual cut with a simple scissor.

No, you use the blade to score the can. You jab the blade through in one spot, and squeeze the top of the can and it will tear along the line

"I'm trying to figure out how to make a cleaner cut." Why, with a razor blade and some patience, grasshopper! :-)

Good to go! Ain't as pretty, But the insulator made the alcohol last quite some time. As in, After 20 minutes it hadn't gone out, so i blew it out and refilled, put it in a baggy and it's ready to be used again.

I would suggest if you ever need this.. build a small fire, use it's embers to heat it up because it does take alot of heat to catch the fumes, however it feed's itself when it's going.

One flaw is it's lack of wind proofing, but there isnt much you can do about that except maybe make some wind blockers/ heat reflectors out of a cardboard box and some tinfoil.

Aluminum, having a low gradient heat temperature makes it possible to toss this into your pocket after about one minute of cool down.

Five stars from me, great Instructable!

I'm having some trouble getting mine together every time i try to get them together i have one of two things happen
1. one or both of the cans tear
2. one of the cans dents itself to go into the leaving a hole between the two of them letting fuel leak
any advice would help greatly

Just made my first one and it took me a bit (was looking at a bunch of different instructables) to get it fired up. The tip on preheating it made my take right off....can't wait to use it this coming weekend so I can have COFFEE while camping!!! Thanks great job!!!

Had my scout troop make a few of these. The boys had lots of fun making them, but couldn't get them lit. (this was my first effort and I should have tried it out at home first)

I discovered that you need to get these pretty hot before they will light.

All the isopropyl alcohol I've seen on store shelves lately is 50% water.
I am using paint thinner which is the cheapest but not healthy fuel,
it is carcinogenic if inhaled too much, but so cheap, you can buy it at any book store or paint store, 1L=0,35$ in my country, probably less in stronger countries(USA, england, france, deutschland, russia.......)
JUST QUICK QUESTION, HOW MUCH DOES IT LAST WHEN YOU FULLY CHARGE IT?

I have now made two of these stoves. One with the insulation, another without. Both burn, but only for a short period- definitely not enough time to boil any water. We're talking about a minute. Any suggestions?
Make the can 2 inches in height instead of just 1 inch... Then you can put more fuel into it.
really, if you want to have that much fuel, than you really are running a red hazard of an explosion. One inch should be enough, and like he said, a couple of tablespoons is enough to boil a cup of water.
how about 1 1/2 inches? :D
you would be surprised how short of time it takes to boil water with one of these. i made one of these out of smaller cans and was able to boil two 1 1/2 cup cans of water in the time it was burning.
The "insulation" is actually a wick, only NK5 chose to use fiberglass.

can i use denatured alcohol?
jj.inc tercielo3 years ago
Just about anything flammable that vaporizes, paint thinner might even work.
thanks..so i can use nailpolish remover.will veniger work.....
nail polish remover definitely, I am not sure about viniger

Vinegar is NOT a flammable (it is in fact an acid) thus it will not burn... hope this answers your question
