SortStack #252 — 2027-02-16

By weight · Order from lightest to heaviest.

1. A single office staple 33 mg

   Heavier than a grain of rice — staples are solid steel wire, and a standard strip glues 210 of them together.

2. An adult male wild boar 90 kg

   Wild boars are thriving so well they have spread or been introduced to every continent except Antarctica.

3. A fully equipped fire engine 18 t

   Around 2,000 liters of onboard water account for a chunk of the heft — plus ladders, hoses, and hydraulic rescue tools.

4. An adult male sperm whale 45 t

   Its clicks reach about 230 decibels — the loudest animal sound on Earth — and a third of its body is one giant sonar-focusing nose.

5. A SpaceX Falcon 9 rocket, fully fueled on the launch pad 549 t

   More than 95% of that is propellant; the reusable first-stage booster lands weighing almost nothing by comparison.

6. The Motherland Calls statue in Volgograd, Russia 8K t

   Twice the height of the Statue of Liberty, sword included, she is not anchored to her base — held in place by gravity alone.
