“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 Gravity bong will give you a dense, pressurized hit with no loss of smoke in the process.”
