i have a cold draft contained by my apartment and i'm not sure where
it's coming from. someone at work told me to use smoke from incense to find where on earth the air slick is.
Answers:    Use a candle. Incense can be bought at any tobacco store, convient store, dollar store.
you can get insence sticks from any well brought-up garden centre. Another point you can try is using a lit candle. The draught direction will become apparent by the course the flame is blowing. Hope this helps.

PS scrutinize out you dont drip wax on your carpet tho
