I'm not particularly interested in death or body disposal, but I keep coming across fascinating ideas on the topic.  There's resomation, which is liquefying a body in acid.  There's excarnation, which usually involves vultures eating the flesh.  But I just learned about promession which consists of freeze drying a body then vibrating it until it disintegrates into a powder.  I heard about it on the 99% Invisible episode Towers of Silence, which was nearly identical to the Radiolab episode on the same topic, but by begrudgingly listening to it, I learned a new weird thing. #nature
