UPDATE: I made the penny can stove. It worked wonderfully, boiled water in about 7 minutes, and I even cooked a package of Top Ramon noodles.
Notes:
-I did this experiment in my fireplace.
-Even though the holes are to the side, if you set the pot directly onto the can it will put the fire out in about a minute. Once I re-lit the stove, I just used the log holder in the fire place with about 1" between the rim of the stove and the bottom of the pot and that worked fine.
-It turned my pot black. So now I have to clean it or get a new one.
-I used about half a bottle of $1.99 Zippo lighter fluid and had the stove going for at least 30 minutes. I got bored watching it and put it out.
-Blowing it out doesn't work.
-REMEMBER TO KEEP THE PENNY OR BOLT OVER THE FILL HOLE.
-I took video, but don't know what format it is in and can't upload it to photo bucket.
Only draw back I see is having fuel on hand. Otherwise, very compact and handy.
