Buy a cheap stainless steel tin, bash a few holes in the side at the bottom,
rip about an inch strip from half of the top and use WOOD. Don't worry, CALM
can't get upset as it's not a campfire when you do this, it's just a stove.
Cram some fencing wire into a ball and push it into the bottom of the tin.
Buy it, don't steal it! Never ending source of fuel (sticks, from TREES &
BUSHES, there's lots of 'em). Just remember, be safe with matches & fire.
Cheers,
Gyro
