Novel DesignThe New Design, Hourglass Shape, Can Make The Airflow Easier To Control And Get A Better Smoking Experience.Feature:This water pipe made of glass can rotate 360º and move dynamically through the interaction of the water circulation to counter the airflow and gravity, thereby producing a constant and cool flue gas. How To Use:1- To fill, rotate the product unit so the globes are perpendicular to the base.Unscrew the globe on top by turning counter-clockwise.2- Fill the bottom globe with water through the pass-through hole in the lid (fill to the edge of the unit, but do not overfill). Then wipe down the threads on the globe using a dry cloth.3- Confirm rubber seal is seated in the unit and reattach the top globe by turning the piece clockwise until tight.4- Now, choose your bowl & materials and prepare for pure bliss5- Rotate the unit in either direction by pushing the top globe towards the bottom.6- Once the water begins to drain, ignite your bowl until gravity takes over. The water inside creates a slow & steady draw that lights your materials fully controlled by how far you turn the unit Be careful not to light too much material.7- Once the top chamber is fully drained, simply rotate the unit again until perpendicular to have the smoke forced out. Rotate back into a parallel position to pause the smoke output. Since the smoke is forced out via gravity, mouth-to-mouthpiece contact is not necessary.Warranty:1.Due to different computers display colors differently, the color of the actual item may vary slightly from the above images,Thanks for your understanding.2.Since the size above is measured by hand, the size of the actual item you received could be slightly different from the size above.
