Fuzzy's Lil' Stove
A.K.A. (Also Known As)

How to make an Alcohol Stove from a Soda Can


This stove weighs less than 10 grams (about 1/3 of an ounce).
One ounce of 70% Isopropyl Rubbing Alcohol will boil a pint (500 ml) of water in about 6 minutes. (At sea level.)

This project must be done under parental supervision!


This project is for intelligent and careful ADULTS, if you don't fit into ALL of the previous categories DO NOT attempt this project -- You agree to assume all legal, moral, financial and medical responsibility should you attempt this project.  You also agree that the total liability of this product is the amount paid; i.e. free advice is worth what you pay, and hopefully more.


Wear Work Gloves AND Safety Glasses while making this stove, you will be working with very sharp edges


Use the stove outdoors with a 5 gallon bucket of water or garden hose and a fire extinguisher to put out any unexpected fires.


Keep away from children!  Sharp edges, fire and poison are not for little ones.


Use only outdoors, in a safe large fire pit area, never in a drought / fire hazard situation.


This stove will run on 70% Isopropyl Alcohol, this is the only fuel I have tested it on.


DO NOT use of anything else!


If you get aluminum hot enough it will actually burn, so please don't use any other fuels.


The stove is very hot after use, handle with care.


Never move the stove while it is ignited.


Okay, now that my lawyer is happy, let's get down to business.


This project will take about 20 minutes to do, mostly to gather the tools.


I hope you only need to use this stove for recreational purposes.


Please enjoy this project wisely,

Upcoming Enhancements:





This project started because I was looking for some more of these stoves.  The Simmons Safe Sport stove. A really simple stove to use, but the place I had bought it from no longer carries it and has no clue if they will ever get more. Searches on the net yielded only Shioshio's webpage. The stove in use photo was taken just as the stove got hot, and the flames were not up to full height.


The Simmons Safe Sport Stove is slightly smaller in diameter than a soda can. The stand is a nicely made steel wire frame. The stove is a cup with an insert that goes almost to the bottom. With jet holes near the top of the cup. The metal insert gets heated up and boils the alcohol, when the fumes rise to the top and out the jets and get ignited. When all of the jets flame up it is time to put the pot on. You heat up the fuel by pouring in about an ounce or two and ignite it and let the flame rise up though the center, this heats the cup up and gets the fuel to boil. You fill it above the bottom of the insert, just like on my stove.

Supplies & Tools:


Work Gloves
Safety Glasses
A 12 oz soda can
A clean used tuna can - 6 ounce can
News paper for a quick project cleanup
Can opener
Needle nose pliers
Sharp heavy duty scissors -- not your wife's sewing scissors.
A nail or screw or ice pick - to poke some holes
Sand paper or a metal file
Magic Marker (permanent marker)
1 pint 70% Isopropyl (Rubbing) Alcohol



Instructions - assembly:

Remember: if you mess up you will have to drink another soda! : )

  1. Spread out the newspaper on the work surface, to catch the metal cuttings. Do as I say, not as I do! : )

  2. Put on and Wear Work Gloves

  3. Put on and Safety Glasses

  4. Take the scissors or nail or ice pick and poke 4 SMALL holes in the upper lip as shown. Spaced every 90 degrees. This allows the fuel to flow evenly while burning.

  5. Use the can opener and remove the inside top where the mouth is - keeping the thick rim, this is not easy. Some lifting of the can opener and pushing will be needed while turning to get the gear teeth to move along. Go around the rim a few times (3-5), this will help cut the seam better.

  6. Push through the inside top and let it fall in, you may not be able to do this until much later; after the wrinkling of the can.  Watch out for the burrs from the poked holes and other sharp edges.

  7. Using the needle nose pliers rub & crush any burrs made by the can opener and or the ice pick / nail.



  8. Draw a circle around the can about 1" (25 mm) up from the bottom and another circle 2" (50 mm) down from the top.

  9. Cut the can open between the middle of these two lines be very careful the edges will be very sharp! It is okay if it is messy, you will clean up these in the next two steps.

  10. Cut the BOTTOM portion on the line, use this one for your practice. Cut a nice clean edge, no nicks or slivers to injure yourself on - this does not need to be level, just very smooth.


  11. Take the TOP portion and cut on the line, Again make sure you have no nicks or slivers -- the straighter the better, this is affects the leveling of the cooking pot.

  12. Using the file or sand paper smooth ALL edges and burrs.

    This is the TOP section shown upside down.
    So you can see how to 'wrinkle' the can.


  13. On the TOP portion, using the needle nose pliers gently wrinkle the "wrinkle to here" line you want to twist the pliers to make a ruffle in the edge of the can, you want the ruffles / wrinkles, but not to big or wide. Make 6 to 10 wrinkles.
    Use a rounded piece of lumber and gently dent in some grooves - be careful not to tear the metal.

    These wrinkles will do several things:

    1. Make the can stronger to support the pot.

    2. Allow the top half to slide into the bottom half.

    3. Allow the vapors to escape up the side and act as flame jets.

  14.  Carefully insert the TOP portion into the BOTTOM portion.

  15. If working with different sized cans, use the mouth opening as a measurement guide. The top height should be the 1 to 1.25 the diameter of the mouth opening. The bottom height should be 1/4 the diameter of the mouth opening.

You're done with the building portion.


I will be trying a Foster's Beer Can - a really big can of beer, this should allow for a taller stove and hold the pot better. See Below!


This little stove weighs less than 10 grams, ~1/3 of an ounce!



Theory of operation: (Oh, no not some boring prattling)

Well, too bad. When you make something you should have a clue how it works.  This won't hurt too much.


The fuel (70% Isopropyl [Rubbing] Alcohol)  is poured into the center and ignited.  The flame inside the chamber causes the top half to heat up, when the outside edge is hot enough the fuel starts to vaporize and mists out the sides (because of the wrinkles / ruffles).  This vapor is then ignited by the flame from the center flame -- all of this happens in about 30 seconds or less.


See, was that bad?


Instructions - use:


Big Flame - no pot on top



stove lit with pot on top


  1. This project must be done under parental supervision!

  2. DO ONLY OUTDOORS (outside) and have a fire extinguisher ready! And 5 gallon bucket of water or garden hose.

  3. Place the stove on solid level ground.

  4. Use only in an approved fire pit.

  5. Never use in during fire hazard conditions.

  6. This stove is not designed to be left unattended!

  7. I can't think of any other stupid things not to do, so don't do it if I'd think it's stupid.

  8. The fuel (70% Isopropyl [Rubbing] Alcohol)  is poured into the center fill to just above the top can's bottom lip and well below the lower can's upper edge (on the outside).

  9. Be sure no fuel is on your hands before you ignite the stove.

  10. Ignite using a long match or long tipped lighter for barbecues.

  11. Wait about 30 seconds, for the outside edge to start flaming. Typically about 10-15 seconds

  12. The stove needs to be conditioned - to burn off the plastic and paints used on decorating the can. Use one ounce of fuel on letting the stove burn without a pot on top.

  13. When re-filling the stove be sure the fire is completely out and the stove is cool -- thus avoiding an unexpected ignition of the stove.

  14. Place pot carefully centered on the stove.

  15. DO NOT STIR your pot on this stove, you will need to make a support for your pot.  That is an exercise left for the student : ) -- I've always wanted to say that.  Hint: take a big tin / metal can and cut out the top and bottom and cut notches into it.  See photo below for a nice example - triangle notches will do.

  16. Extinguishing the flame, you can not blow out the flame unless the pot is on top then a strong breath will do it. Or use a tuna can dropped upside down on to the stove.

  17. Remember the stove and pot are HOT after use.



Fuel Storage:



Evolution of designs:

Sorry for the bad photo. These were taken with an older camera and many of the earlier stoves were thrown out, so this is the only photo that exists of the evolution.




The Foster's Mishap:

Made the stove using the above technique, from a can I found on the side of the road - Rotten Litter Bugs!  The metal had an odd (strange) feel to it, not like the other cans and the bottom had 'rusted' / tarnished.  The thick rim had been gnawed (chewed - removed) off while using the can opener.  Still we marched on, to make the stove.



Poured some fuel in and it would not stay light so, cheated [no, I'm not gonna tell you how - it worked on the other cans] and the flame started. It roared up nice and big and then the top lip caved in, and then the flame jumped even bigger. I started to get very worried!  And grabbed the big bucket of water, but waited and the can started to cave in upon itself - the fuel was mostly used up.


The metal did not 'feel', correct, like the other cans.


I will be on the look out for another brand of beverage using the jumbo [big] size cans.

20DEC2000  Just found that Arizona Iced Tea makes a 700ml version, it's not a full liter like the Foster's but it was bigger. And I will be testing it soon.

The moral of this example:

This can be a dangerous project, please proceed carefully!
