The Flap Jack is an exceptionally light-weight stove.  It only weighs 7 lbs.!!  A 300 lb. man can stand on it, and it will not collapse.   It can boil a cup of water in 5-7 minutes and will store a mini shelf with 2 feet of 4" pipe in the fire box.  It will heat a small tent or ice house and will hold the heat for 1-2 hrs.  Its dimensions are 7" x 9" x 15" with a 4" chimney hole.  It will fit almost anywhere and feeds 1-2 people.
