I'm watching the show now
The chimney on fire incident for Brook and Dave is a thing I thought very often
How can coexist a wood structure with a fire heating
How to make a small enough cabin (esear to build and keep warm in a survival situation) without burning it accidentally
I never made one but I'm really interested
I've seen pictures and drawings of wood chimneys. Probably the inside was sealed with clay or stones still the idea it could be easily be set on fire is allways in my mind.
