We had a penny can stove thread here a few years ago. I've built three or four of them. I think there are better designs than that one. Would you like me to dig up a few Youtube videos? There are about 100 different Youtube videos of penny can stoves. They are fun. Zippo fluid works great. DO NOT USE COLEMAN WHITE GAS. DO NOT USE COLEMAN WHITE GAS.

I made one like this kind, but found it needed a stand because if I put a pot right on top, it would go out. This video is good to watch because the cutting method used is better.
