Realistic Smoke from Chimneys

[Murph]

Quick one just in case anyone is interested ...... Made a set of buildings recently and I included a ships chandler , decided to give it a hollow chimney with no capping or pots, 2cm gap at bottom.  Got some incense cones complete with round metal base, glued base underneath chimney, lit cone and it works beautifully, hardly any heat in metal base as it only gives off smoke not flame and has proved safe , and it makes the model room smell nice , the aroma  was called Angels Breath !!!  How the hell does anyone know what Angels Breath smell like ??  Couldn't find any Beamish and Madras Curry ones !!
