By weight · Order from lightest to heaviest.

1. A single office staple 33 mg

   Heavier than a grain of rice — staples are solid steel wire, and a standard strip glues 210 of them together.

2. 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.

3. 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.

4. A Boeing 777-300ER airliner at maximum takeoff weight 351.5 t

   Each of its GE90 engines is so wide that a Boeing 737 fuselage could very nearly fit inside the cowling.

5. The steel arch of the Sydney Harbour Bridge 39K t

   The arch rises and falls up to 18 cm with temperature swings; locals affectionately call the bridge 'the Coathanger'.

6. The Burj Khalifa in Dubai 500K t

   The world's tallest building is tall enough to watch the sunset at the base, ride the elevator up, and watch it set again.
