SortStack #3410 — 2035-10-10

By speed · Order from slowest to fastest.

1. The growth of a cave stalactite 0.1 mm/year

   Most stalactites lengthen by less than a tenth of a millimetre a year, dripping mineral by mineral over millennia.

2. A mosquito in flight 2.4 km/h

   Only female mosquitoes bite; they need a blood meal to develop their eggs, while males sip flower nectar.

3. A domestic cat at full sprint 49 km/h

   A house cat can outsprint many dogs over short distances, but tires quickly after the burst.

4. A speeding hovercraft 145 km/h

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

5. 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.

6. A Bugatti Chiron at top speed 510 km/h

   The Chiron is electronically limited; unleashed, its tyres would tear themselves apart from the sheer forces.
