SortStack #1302 — 2030-01-01

By weight · Order from lightest to heaviest.

1. An Etruscan shrew, the world's smallest mammal by mass 1.8 g

   Its heart beats up to 1,500 times a minute, and it must eat about twice its body weight in insects every single day.

2. An upright piano 220 kg

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

3. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

4. The International Space Station 420 t

   Assembled over 42 flights, it circles Earth 16 times a day at 28,000 km/h, so its crew sees 16 sunrises daily.

5. 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.

6. The Golden Gate Bridge 805K t

   Its two main cables contain enough wire to circle the Earth three times, and painting crews never actually finish — they cycle forever.
