The November 10, 2026 puzzle ran from a wine bottle at 30 cm to the Moon at 3,474.8 km — 7 orders of magnitude apart, drawing on vehicles, space, dinosaurs, music, food & drink. The pair furthest apart was round 5: a wine bottle is 1.7× as big as a stage microphone.
ROUND 1
How long is a Boeing 747 compared with the International Space Station?
Reveal the answer
Answer: Boeing 747 — 70.7 m. A Boeing 747 measures 70.7 m (length / span), which is about 1.5× smaller than the reference, the International Space Station at 109 m.
A classic Boeing 747 is roughly 70.7 metres long.
How people guessed: across 7 runs the typical guess was 51.7 m — 27% too small. The most common miss is picturing a Boeing 747 far smaller than the International Space Station really allows.
Answer: The Moon — 3,474.8 km. The Moon measures 3,474.8 km (length / span), which is about 1.2× smaller than the reference, Brazil at 4,320 km.
The Moon’s mean diameter is about 3,475 kilometres.
How people guessed: across 7 runs the typical guess was 6,536.2 km — 88% too large. The most common miss is picturing the Moon far bigger than Brazil really allows.
