Gravity Vortex water pipe offers durability, stability and character. Gravity Vortex gives its user the bona fide experience of a rich, thick, and clean smoke. Through the mouthpiece, fill the top chamber with water and insert the glass bowl filled with your favorite tobacco. Light the tobacco and at the same time gently turn the valve to open, and allow the water to flow to the bottom chamber. This creates the gravitational suction. Close the valve and enjoy the pure thick smoke. Reverse the process by opening the valve, and turning the Gravity Vortex water pipe upside allowing the water to flow back to the top chamber.
