Rural Saw Mill

Trying to decide on the next video is nearly always a struggle!
I've got a few ideas and on the main page of this website I have a pole where you can make suggestions which is a big help.
At this stage I'm planning to film a video and add live smoke to a building, the building of choice at this stage is the Woodland Scenics Rural Saw Mill.

It's only a very small kit, which makes it perfect for filming a tutorial on. I'm yet to do a commercial kit tutorial but with the added effect of live smoke I think this will turn out quite good. 
The plan is to add this detail to the "Realistic Scenery Vol 4" diorama and have it protruding out of the shed slightly with the smoke emanating out from the small chimney.

I'm still throwing ideas for the smoke around? Of course it has to be safe and contained to prevent igniting the rest of the layout!
Thus far I'm working with incense sticks contained in a heat proof container and I'm also looking into the dry ice option however dry ice tends to act like fog and sits on the ground rather than dissipate into the atmosphere.
I guess well have to do some experimenting! I'm looking forward to this tutorial and I'm hopeful that it works as planned.
