Lol, Bmarks, sounds like a truly mediveal city fire... :P Everyone to the buckets!!!
In a similar story I decided a lava lamp would be a cool thing to create for my barn, so i stuck a fence post to the roof, constructed a lamp and poor the lava in. As it was getting dark I ran back home, slept and returned to stare in awe at my new lava lamp. Well the place was lit for sure, I'll tell jah that lol. Totally forgot the fence is made of wood and wood plus lava = fire.
