Make Mercury Metal (Decomposition of Mercury (II) Oxide)

Today I perform the decomposition reaction of mercury (II) oxide (also known as mercuric oxide), which produces oxygen gas and mercury metal. Then, I test the oxygen to see if it is pure or not by using a charred splint. Have any suggestions for videos in the future?
