Why it works
The 0:00–0:03 cube-and-flame setup teaches a familiar rule before introducing the technical term, and the 0:13–0:21 prediction question makes viewers anticipate the bend. The same silver-and-copper object becomes a working switch at 0:42–0:52; the most-replayed interval, 0:48.6–0:49.2, falls within that practical proof. Sparse labels and deliberate pauses make the 150-word explanation readable without hard cuts.
