By duration · Order from shortest to longest.

1. A camera speedlight flash firing at full power 1 ms

   At low power settings, flash bursts get even shorter — down to around 1/30,000 of a second, fast enough to freeze a bursting balloon mid-pop.

2. A single round of professional boxing 3 min

   Round length was standardized by the 1867 Queensberry Rules, which also introduced gloves — before that, bare-knuckle rounds ended only with a knockdown.

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. Charles Lindbergh's solo flight from New York to Paris 33.5 h

   Lindbergh went without sleep so long he reported hallucinating ghostly figures in the cockpit somewhere over the Atlantic.

5. The Edinburgh Festival Fringe 25 days

   The world's largest arts festival stages over 3,000 shows — by ticket sales it trails only the Olympics and the football World Cup.

6. One year on Mercury (a full orbit of the Sun) 88 days

   Mercury's spin is so slow that a single sunrise-to-sunrise day there lasts about two of its years — you could outwalk its sunset.
