By weight · Order from lightest to heaviest.

1. A FIFA regulation soccer ball 430 g

   World Cup balls are tested in wind tunnels; the 2010 'Jabulani' was so smooth that goalkeepers complained it swerved unpredictably.

2. An adult giant panda 110 kg

   Pandas spend up to 14 hours a day eating bamboo because they digest only about a fifth of what they swallow.

3. An upright piano 220 kg

   Inside is a cast-iron plate holding strings at a combined tension of roughly 18 tonnes of pull.

4. An adult male white rhinoceros 2.3 t

   The 'white' is likely a mistranslation of the Dutch 'wijd', meaning wide — describing its broad, lawn-mowing mouth.

5. A fully loaded Triple-E class container ship 250K t

   It hauls around 18,000 containers with a crew of only about 22 — fewer people than a fast-food restaurant shift.

6. The supertanker Seawise Giant, fully loaded 650K t

   The longest ship ever built could not transit the Suez or Panama canals — or even the English Channel — when fully laden.
