make a filter...stick dryer sheets in a bottle and cut a hole in the end...blow the smoke through the bottle and the smell will be negligible...you can use paper towels or toilet paper instead of dryer sheets but it won't work as well

you should probabally do it your closet and take lots of precautions just to be sure.
KiEfBoyjBm Reviewed by KiEfBoyjBm on . IF I were to smoke from a waterfall gravity bong.... In my closet at around 1am, then after, I'm done my bowl, close the closet door and put shirts at the bottom of the door to cover any smell that would get out.......would the smell of weed from inside the closet get out and spread in my room, or would it not smell at all in the morning. (Im' a little buzzed at the moment so bear with me.) Rating: 5
