Great Beer Can Burner
 

There's a lot of beer can stove designs out there but that was a nice simple one. They were playing with fire though when it came to cutting the can with the knife - I know as I've the scars on my hand from doing something similar. :thumbdown:

I agree - not the safest way to use a knife! The burner is very simple and it might be ok on a solid surface outdoors, but I would never want to use it in a tent. If it got knocked over there would be an instant fireball as the fuel spilled out.
