Poison. Before the days of advanced science and forensics, poison was the quiet, preferred method of murder. In the early days of science, poisons were usually kept in colored glass bottles that were various hues of dark amber or cobalt blue, as an immediate warning to read the label. Some poison bottles were shaped like coffins, and a scarce few clay bottles have been found shaped like a human bone. Eventually, the skull and crossbones were adopted for labels ― the universal sign of death, in case someone could not read. Have a very, merry Christmas with poison snow. Fun for the entire family.
