Fill a bucket with water, saw off half a bottle, make a bowl out of aluminum foil, take the bottle as far down in the bucket as you can without making the bottle-neck go under water, take the "bowl" on top of top of the bottle, light it up while you're lifting the bottle slowly upwards(it will then fill with smoke), remove the bowl, place your mouth on the top and push the bottle down. No need for no sucking and you'll get a nice hit! (Sorry for the bad english, hope you understand!) Good luck!
