SortStack #1079 — 2029-05-23

By speed · Order from slowest to fastest.

1. A Komodo dragon walking 4.8 km/h

   The largest lizard alive, it has venom glands and a bite that can topple prey far larger than itself.

2. A striking barracuda 42 km/h

   Barracudas can lunge in sudden bursts to ambush prey, sometimes mistaking a swimmer's shiny jewellery for fish.

3. A record tennis serve 270 km/h

   The fastest serves leave the racket so quickly the returner must react before the ball has even crossed the net.

4. A golf ball off the driver 340 km/h

   A driven golf ball can briefly spin thousands of times a minute, which is what makes it climb and hold the air.

5. A Boeing 747 cruising 920 km/h

   The 747's hump exists because the cockpit was put on an upper deck so the nose could hinge open for cargo.

6. The Earth orbiting the Sun 107K km/h

   We are all hurtling around the Sun fast enough to cross between two cities in a single second, yet we feel nothing.
