This is my take on the pop can camp stove. I didn't have any other fuel so I used acetone, but you should be able to use almost any liquid fuel, but choose what you put in it carefully, you wouldn't want to put something like petrol in it. Also it has a removable pot holder that slips over it so that you don't have to make a separate one and carry around. It is thin and when empty can easily be slipped into a pocket to take with you on any camping trip.
Disclaimer: I am not responsible for what you do with this, used properly it should be relatively safe, but as anytime you deal with fire BE CAREFUL.
Also, it has been brought to my attention that acetone is carcinogenic, so don't use it.
Step 1: Materials:
You will need these tools:
Razor knife/Exacto knife(any sharp knife could be used)
Awl(or some other sharp pointed object)
You will also need two empty pop cans, I have three in the picture, because I was drinking out of one while i worked(very thirsty work you know).
Step 2: Cut the bottoms off
Start by cutting the first ones bottom off right at the part where the label ends and it curves downward.
Now, on the second one your going to want to cut about 3/4 of an inch above the bottom of the label.
Step 3: Now hammer out the round part
To make it hold the fuel better, use a hammer to flatten down the round part and make it bulge out the other way. Next, on the skinnier bottom use the awl to punch holes around the rim about half an inch apart, and about 10 of them in the center in any manner you want then hammer out the round part. I didn't put my holes in until after i had it bulged out, it should be done before.
