SortStack #2037 — 2032-01-06

By weight · Order from lightest to heaviest.

1. A black garden ant worker 1.5 mg

   Ants can carry 10 to 50 times their own body weight — the square-cube law makes tiny bodies absurdly strong for their size.

2. A round loaf of sourdough bread 800 g

   Some sourdough starters are family heirlooms over 150 years old, kept alive by daily feedings of flour and water.

3. A full backyard barbecue propane tank 17 kg

   The familiar grill tank stores propane as a liquid; on a hot summer day the pressure inside can roughly triple.

4. An adult giant panda 110 kg

   Pandas spend up to 14 hours a day eating bamboo because they digest only about a fifth of what they swallow.

5. Big Ben, the Great Bell of Westminster 13.8 t

   Big Ben is the bell, not the tower — and it cracked within months of entering service in 1859; the odd tone is the crack.

6. 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.
