SortStack #267 — 2027-03-03

By speed · Order from slowest to fastest.

1. A duck paddling on water 1.6 km/h

   Ducks have no nerves or blood vessels in their feet, so they can paddle in icy water without feeling the cold.

2. A speeding hovercraft 145 km/h

   A hovercraft floats on a cushion of trapped air, gliding equally well over water, land, ice and mud.

3. A downhill speed skier 255 km/h

   Speed skiers tuck into an egg shape and wear airfoil helmets, accelerating faster than a free-falling skydiver.

4. A 5.56mm rifle bullet 3.1K km/h

   Small, fast rifle rounds tumble on impact, transferring energy in ways a slower, heavier bullet would not.

5. The International Space Station in orbit 28K km/h

   The station circles Earth so fast its crew sees about 16 sunrises and sunsets every single day.

6. A meteor entering the atmosphere 50K km/h

   Most shooting stars are no bigger than a grain of sand, burning up bright from sheer speed alone.
