SortStack #105 — 2026-09-22

By weight · Order from lightest to heaviest.

  1. A single grain of table salt 60 µg

    Salt crystals are near-perfect cubes because sodium and chloride ions lock into a rigid lattice — about a million grains fit in one cup.

  2. An unfed female mosquito 2.5 mg

    After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

  3. A full-size kitchen refrigerator 135 kg

    Refrigeration changed cuisine more than almost any invention; Einstein even co-patented a fridge with no moving parts in 1930.

  4. The Statue of Liberty 204 t

    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. 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.

  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'.
