By weight · Order from lightest to heaviest.

1. A McDonald's Big Mac 220 g

   The Economist uses Big Mac prices to compare currency values worldwide — the famously tongue-in-cheek 'Big Mac Index'.

2. An adult male wild boar 90 kg

   Wild boars are thriving so well they have spread or been introduced to every continent except Antarctica.

3. An adult male western lowland gorilla 160 kg

   Silverbacks are several times stronger than a fit human, yet they eat almost nothing but plants and the occasional termite.

4. A Thoroughbred racehorse 570 kg

   At full gallop a racehorse's heart pumps roughly 240 liters of blood per minute — ten times its resting rate.

5. A Space Shuttle orbiter, empty on the runway 78 t

   Returning from orbit, the shuttle was a glider with no engines for a second try — every landing had to work the first time.

6. Howard Hughes' Spruce Goose flying boat 113 t

   It held the record for largest wingspan of any aircraft until 2019, yet flew exactly once, in 1947 — for about 26 seconds.
