SortStack #1645 — 2030-12-10

By weight · Order from lightest to heaviest.

1. A common housefly 12 mg

   Houseflies beat their wings around 200 times per second, which produces their signature buzzing pitch near the note F.

2. A single kernel of corn 300 mg

   Each kernel is botanically a complete fruit, and a typical ear carries an even number of rows — most often sixteen.

3. An Etruscan shrew, the world's smallest mammal by mass 1.8 g

   Its heart beats up to 1,500 times a minute, and it must eat about twice its body weight in insects every single day.

4. A modern US penny 2.5 g

   Pennies have been mostly zinc since 1982 — only the thin outer coating is actually copper.

5. A FIFA regulation soccer ball 430 g

   World Cup balls are tested in wind tunnels; the 2010 'Jabulani' was so smooth that goalkeepers complained it swerved unpredictably.

6. The Motherland Calls statue in Volgograd, Russia 8K t

   Twice the height of the Statue of Liberty, sword included, she is not anchored to her base — held in place by gravity alone.
