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. Usain Bolt's 100 m world record run 9.6 sec

   Bolt ran 9.58 in Berlin 2009, hitting a top speed of 44.7 km/h — faster than the speed limit on many city streets.

3. One full rotation of the London Eye 30 min

   It moves so slowly — about 0.9 km/h — that it usually doesn't stop to let passengers on; you simply step into the moving capsule.

4. The average adult's actual night of sleep 6.8 h

   Smartphone-tracking studies put the global average well under the recommended eight hours — and humans sleep less than virtually any other primate.

5. The main construction of Notre-Dame de Paris 97 years

   The medieval build ran from 1163 to 1260 — yet after the 2019 fire, the cathedral was restored and reopened in just five years.

6. The Republic of Venice 1.1K years

   The 1,100-year republic elected 120 doges using a bizarre multi-round lottery system specifically designed to prevent vote-rigging.
