I think the best idea would be to go outside:thumbsup:
but if thats not a possibility, than i would point the fan out the window and blow your hits into it... you might also want to use an apple pipe instead of a pop can because, if you make the bowl deep enough, you can put your finger or a coin over it to stop the extra smoke....Maybe find some air freshener or something for after youre done..:jointsmile:
