you take a empty 2 liter bottle..cut it in half..save the top part..take the cap of the bottle and use whatever you can to melt and mold in a little bowl at the top...get a bucket of water..
put some bud in the bowl screw it tight to the bottle, push the bottle to the bottom of the bucket (without gettin water to the top of course) and then light the bowl...slowly raise the bottle upwards while lighting the bowl and the empty 2 liter half will fill up with mad smoke...dont lift the bottle out of the water completely...then unscrew the bottle top, put your mouth on top of the bottle and push the bottle down and inhale all that mad smoke...crazy ass hit.
