Nice Idea!
I really liked your way of presenting the philosophies in this series--your works are entertaining as well as educational!
To people who are wondering what those 'little things' are, I believe they are chunks of coal used in special ovens (usually for water boiling). These things are typically found in eastern Asia, although they were more ubiquitous in the past when electricity was not widely distributed. After use, their colour changes from pitch black to grayish white, that's what happened to the girlie coal... (The picture at the end of the film is an actual coal chunk, presumably used)
