A terrarium, a column, a ledger

The terrarium is sealed: every gram of water is counted in three places -- puddle, air, lid -- and their total never changes because the engine moves grams, it never makes or loses them. The column fills grain-by-grain to the porosity fraction. Commit a prediction before every run.
