Boxma Plumbing and Heating Inc. A toast to everyone! Haha just kidding this is a glass of liquid propane, and this morning it was cold enough Andrew was able to pour himself a glass of liquid propane. Propane has a boiling point of -42.2 degree Celcius. This morning at -43 outside and 2677 feet above sea level, propane will stay liquid under no pressure. #funfact Photo of liquid propane in a stemmed wine glass.
