A easy and inexpensive stove, made from recycled materials.
Traditionally a large coffee tin was used, back when the didn't have boxboard sides or made from plastic. Any large tin can will do.
Also known as a "Hobo Stove". I'm not sure what the politically correct term would be, but these items are a throw back to when these terms were part of our acceptable language.
The fuel for inside this type of stove was traditionally a Buddy Burner, made from a tuna can, cardboard, and wax. Another great recycled item project! Other small burners will work too.
