Submarine 14mm If you are ever after a vehicle to take a deep dive into the depths of your mind. I think this might just be it. The Submarine 14mm  is a beautiful little desktop water pipe. This uses a whip which is connected to the bubbler via a 14mm whip adapter. You can pick this bubbler up when in use but it is usually best used on a flat surface as this ensures the water level stays above the long tube slit percolator. If using this in your hands, just keep in mind it should be kept relatively flat so it operates correctly.  The inlet of the Submarine is a 14mm female joint and it also exists through a 14mm female joint. The included whip adapter is inserted into the outlet along with the whip and glass mouthpiece. This unique little bubbler really does have a unique feel to it and is certainly worth some consideration. You will find for its size it produces a nice smooth vapour.
