   Pharmacists standardized the 'drop' centuries ago: twenty drops make roughly one milliliter.

   Researchers computed this from global census data; North America's average is about 20 kg heavier than Asia's.

   Each Steinway Model D takes about a year to build and contains over 12,000 individual parts.

   Hippos cannot actually swim — they sink and gallop along the riverbed, surfacing to breathe every few minutes.

5. An M1 Abrams main battle tank 62 t

   Despite the bulk it tops 65 km/h, powered by a jet-style gas turbine engine that can run on almost any fuel.

6. 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'.
