  1. A chameleon's tongue reaching its insect prey 72 ms

    Small chameleons have the fastest tongues, accelerating at hundreds of g — proportionally the most powerful movement of any reptile, bird, or mammal.

  2. One human heartbeat at rest 798 ms

    Your heart beats roughly 100,000 times a day and around 3 billion times in a lifetime, pumping enough blood to fill an Olympic pool several times over.

  3. 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.

  4. The Wimbledon tennis championships 14 days

    The tournament's famous rest day, the 'Middle Sunday', was only abolished in 2022 after 145 years of tradition.

  5. The construction of the Empire State Building 1.1 years

    Crews added roughly four and a half storeys per week, finishing ahead of schedule and under budget during the Great Depression.

  6. The age of the Lascaux cave paintings 17K years
