SortStack #1855 — 2031-07-08

By weight · Order from lightest to heaviest.

  1. 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.

  2. A house sparrow 28 g

    House sparrows have followed humans to every continent except Antarctica — one pair even nested deep inside an English coal mine.

  3. A full deck of 52 playing cards 94 g

    Shuffle properly and you have almost certainly created an ordering of the deck no human in history has ever seen before.

  4. 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.

  5. An adult male giraffe 1.2 t

    A giraffe's heart generates about double the blood pressure of most mammals to push blood two meters up its neck to the brain.

  6. 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.
