Size It Up answer: September 24
The five Mixed silhouettes for September 24, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.
Day 21 ran from a Tasmanian devil (65 cm) to the Parthenon (69.5 m). The widest gap was round 4, Blue Whale against Jet Ski, at 8.2×; the closest call was round 1, Bed Pillow against North American Beaver, only 1.4× apart — the kind of round that separates a 90 from a 60.
