By speed · Order from slowest to fastest.

1. A charging African elephant 28 km/h

   Despite their bulk, elephants are the only animals that cannot jump, keeping at least one foot down at all times.

2. A falling raindrop 34 km/h

   Raindrops are not teardrop-shaped; they flatten into tiny hamburger buns as they fall through the air.

3. A charging lion 83 km/h

   Lions are the only big cats that live in groups, and a male's roar can be heard up to eight kilometres away.

4. 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.

5. A maglev train at record speed 460 km/h

   Maglev trains float on magnets with no wheels, so the only friction left to overcome is the air itself.

6. A volcanic pyroclastic flow 700 km/h

   A pyroclastic flow is a searing avalanche of gas and ash that buried Pompeii's residents almost instantly.
