Things You Probably Need
1. weed
2. 2ltr bottle
3. bowl
4. scissors
5. Something to place the 2ltr bottle in

First take the scissors and cut the bottom of the 2-liter off. then poke a hole in the cap, place the bowl in the small hole.. then pack the bowl. put the bottle in a bucket or something and fill it with water to a lttle below the neck. and light the bowl, pull up the bottle, then quickly take off the cap and put your lips on the top. finally breath in while pushing down the bottle... hope that makes sense.
