A chalice pipe is like a special kind of pipe that people use to smoke things like tobacco or herbs. It is shaped kind of like a cup, and sometimes it can be brightly colored. You put the herb or tobacco in a small bowl at the bottom of the chalice pipe, and then you light it with a lighter or match. When you breathe in through the top of the chalice pipe, the smoke from the herb or tobacco goes into your mouth and lungs. Some people believe that smoking from a chalice pipe can be a spiritual or cultural experience.
