1. A common housefly 12 mg

   Houseflies beat their wings around 200 times per second, which produces their signature buzzing pitch near the note F.

2. An adult hippopotamus 1.5 t

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

3. A Tesla Model 3 1.8 t

   Around a quarter of the car's entire mass is its battery pack, mounted in the floor for a racing-car center of gravity.

   Her copper skin is only about as thick as two pennies; the green color is a patina that took roughly 30 years to develop.

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 supertanker Seawise Giant, fully loaded 650K t
