one really easy way is to just skip the towel and all that other stuff and just smoke from a socket and blow it as hard as you can out the window. while smoking from a socket, you are able to plug both ends with your hand right after you hit it so no smoke escapes, then just stick your whole head out the window and blooooowwwww. you can even hold your peice out the window if you want. its sorta like smoking half outside.
cant believe no one mentioned the following advice to conceal smell: (this method works with using boels, which i would recommend over a joint for obvious reasons such as weed continues to burn after hit). [ame]http://www.youtube.com/watch?v=0sJmk2lx5KI&feature=youtube_gdata_player[/ame]
I'm gonna try to put an end to these retarded ass threads... Step 1: Fucking buy one of these: Google Image Result for http://upload.wikimedia.org/wikipedia/en/4/4d/Window_Fan.jpg Step 2ut it in the fucking window and turn them both to exhaust. Step 3:Fucking smoke by it and blow your hits towards it. These things make a strong, constant airflow out of your window so unless you blow the smoke towards your door, nobody is going to smell it. You don't have to give yourself a headache with all these tricks, just buy a window fan.
