I am trying to chase down drafts in my house and would like to get
advice on the best way to detect air leaks. I have seen the following
suggestions and/or products on the net and would like to get feedback
from real world experience:

Incense sticks, as sold in hippy shops &c. They produce
a thin stream of visible smoke but seem safer than most
other burning materials.
