SortStack #3598 — 2036-04-15

By weight · Order from lightest to heaviest.

1. A front-loading washing machine 76 kg

   Much of the heft is a deliberate concrete counterweight — without it, the spin cycle would walk the machine across your floor.

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 classic yellow American school bus 11 t

   The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.

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 Antonov An-225 Mriya cargo plane at maximum takeoff weight 640 t

   The heaviest aircraft ever built was destroyed in Ukraine in 2022; 'Mriya' means 'dream' in Ukrainian.

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.
