By duration · Order from shortest to longest.

  1. A mantis shrimp throwing its famous punch 3 ms

    The strike accelerates like a bullet and creates collapsing cavitation bubbles that briefly flash with light and heat — prey gets hit twice by one punch.

  2. An amber traffic light before it turns red 4 sec

    Amber phases are tuned to road speed — typically 3 seconds in town and up to 6 on fast roads, calculated from braking distance physics.

  3. An average human yawn 6 sec

    Yawns are so contagious they jump species: dogs catch yawns from their owners, and even reading the word can trigger one. You're welcome.

  4. A typical national anthem performance at a sports event 1.5 min

    Uruguay's full anthem runs about five minutes, while Japan's 'Kimigayo' has just four lines — the shortest lyrics of any anthem on Earth.

  5. One orbit of Pluto around the Sun 247.9 years

    Pluto hasn't completed a single orbit since its discovery in 1930 — it won't finish its first 'observed year' until 2178.

  6. The age of the oldest known figurative cave painting (Sulawesi) 51.1K years

    The Indonesian rock art depicts wild pigs and human-like figures — painted tens of thousands of years before Lascaux's famous bulls.
