A glycerin bong is a water pipe designed with a glycerin-filled chamber. Glycerin, a non-toxic, thick liquid commonly used in food and cosmetics, has excellent cooling properties. By placing the glycerin-filled part of the bong in the freezer, it cools down significantly. When smoke passes through the chilled glycerin chamber, it cools down, creating a smoother, less harsh hit.
