You need a piece of tubing that goes from the bowl down to near the bottom of the g bong. The tubing has to be air tight around the bowl and there has to be no where air can get in apart from where the bud will be buring, otherwise it will not work. You should be able to lift the bottle up until the end of the tube reaches the water in the bucket without the water level in the g bong moving. As soon as the end of the tube goes about the water level in the bucket the air will start to be drawn down the tube. Ill draw a few pics in a in a bit.
