Step 4: Creating Bottle Seal

Picture of Creating Bottle Seal

CREATE BOTTLE SEAL, this bulge will create a seal between the pipe and the soda bottle. Mark the vertical piece 10-inches from the open end. Using a candle or heat-gun, heat the pipe evenly at this mark until it becomes soft. Grasp pipe on either side of mark and push together to create a slight bulge. Hold the pipe straight until cool and no longer soft.
