You have a couple different options for this step. First, you can use an actual downstem and bowl — the same kind of downstem and bowl combination you’d use in a regular bong. This route requires you to drill a hole into the lid of your plastic bottle. Press the downstem into this hole and slide the bowl into the downstem.
