SortStack #273 — 2027-03-09

By weight · Order from lightest to heaviest.

1. A AAA alkaline battery 11.5 g

   Despite the tiny package, a fresh AAA stores enough energy to hoist an adult human several meters into the air.

2. An adult male western lowland gorilla 160 kg

   Silverbacks are several times stronger than a fit human, yet they eat almost nothing but plants and the occasional termite.

3. A Steinway concert grand piano 480 kg

   Each Steinway Model D takes about a year to build and contains over 12,000 individual parts.

4. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

5. A Space Shuttle orbiter, empty on the runway 78 t

   Returning from orbit, the shuttle was a glider with no engines for a second try — every landing had to work the first time.

6. An Ohio-class nuclear submarine, submerged 18.8K t

   It displaces more than some WWII aircraft carriers and can stay underwater for months, limited mainly by the food supply.
