Why it works
The question is voiced by 0:05 over a single classroom diagram, and the expected answer is overturned by 0:11. Each new constraint gets a legible visual state: pressure arrows at 0:14, a CO₂-filled cutaway at 0:32 (the top replay peak), and a red reactor heat calculation at 2:38. The 3:37 reentry failure and 3:55 survival gag pay off the escalating calculation with a physical outcome.
