SortStack #70 — 2026-08-18

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 monarch butterfly 500 mg

   Despite weighing less than a paperclip, monarchs migrate up to 4,800 km from Canada to mountain forests in central Mexico.

3. A 16-inch MacBook Pro 2.2 kg

   Apple's obsession with grams runs deep: the original 1989 Macintosh Portable weighed more than three of these.

4. 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.

5. An adult male African lion 190 kg

   A lion's roar can be heard up to 8 km away, thanks to uniquely flat, square-shaped vocal folds.

6. 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.
