What "tricks" do you use before, while, or after smoking?

One thing I like to do before smoking out a room is determining the airflow (whether it's going out the room). After setting up the fans and shit but before toweling, I get down low and spark my lighter, putting the flame near the bottom of the door. The air current will pull the flame in a certain direction and lets you know which way it's heading.

Let's hear yours or the ones you've seen
