Term: Demon CO

A humorous reference to carbon monoxide. When charcoal for incense is burned, it can exhaust the air of oxygen and replace it with carbon monoxide (chemical formula: CO). The lack of oxygen can cause dizziness, sickness, unconsciousness, or death. A magician should always have plenty of air in a room when burning incense.
