GRAV | Gravitron Large Gravity Water Pipe

The Large Gravitron® takes the gravity bong out of the dorm room. With this classic design, gravity and pressure work together to give you huge, efficient hits - this sleek glass gravity bong keeps things clean and classy. This closed-system design keeps all your smoke contained until you're ready to blast off, making it an epic bud-saver. Hits are thick and milky with no effort to draw—gravity does all the work. And when you're done, the simple design and straight sides make it a breeze to clean. To use: - Fill the base about halfway with water. - Pack the bowl with dry herb and insert it into the joint at the neck of the bottle. - Light the bowl and lift the bottle at the same time. Don't lift the bottle all the way out of the water, or you'll lose your smoke. - Once the bottle is full of smoke, remove the bowl and place your mouth over the neck, inhaling as you lower the bottle. The Gravitron will give you a dense, pressurized hit with no loss of smoke in the process.
