Why it works
The puzzle is spoken by 0:02.5 and the orange-cube-blue diagram is established in the first half-second, so the audience can start guessing immediately. Seven substantial drawing changes carry the argument from a simpler piston model at 0:07.6 through two assumptions at 0:21–0:34, with arrows supporting the unusual conclusion at 0:52–1:00. The 231-wpm narration keeps the single canvas active while the sparse diagrams make the dense reasoning followable.
