SortStack #3507 — 2036-01-15

By weight · Order from lightest to heaviest.

1. A ruby-throated hummingbird 4 g

   It crosses the Gulf of Mexico nonstop — about 800 km — burning nearly half its body fat in a single 20-hour flight.

2. A liter of water 1 kg

   The kilogram was originally defined in the 1790s as the mass of exactly this much water — the tie was only fully broken in 2019.

3. A whole pineapple 1.2 kg

   Pineapples take nearly two years to grow, and each plant produces just one fruit at a time.

4. A standard Good Delivery gold bar, the kind in bank vaults 12.4 kg

   Smaller than a brick yet heavier than most pet dogs — gold is so dense this bar would fit in a shoebox with room to spare.

5. The Golden Gate Bridge 805K t

   Its two main cables contain enough wire to circle the Earth three times, and painting crews never actually finish — they cycle forever.

6. The Great Pyramid of Giza 5.8M t

   Roughly 2.3 million stone blocks were stacked over about 20 years — averaging a block placed every few minutes of every workday.
