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 standard television commercial 30 sec

   A single Super Bowl slot of this length has sold for over US$7 million — more than US$230,000 per second of airtime.

3. The reign of Queen Elizabeth II 70.5 years

   Her 70 years and 214 days saw 15 UK prime ministers, from Churchill to Truss — she appointed the last one two days before she died.

4. The era of the Crusades, from the first to the fall of Acre 194.9 years

   Nine major crusades spanned 195 years — and the Fourth never reached the Holy Land at all, sacking Christian Constantinople instead.

5. Roman rule over Britain 366.9 years

   Rome governed Britain for 367 years — longer than the entire history of the United States — before abandoning it to defend Italy.

6. How long the Parthenon has been standing 2.5K years

   It survived largely intact for over 2,000 years — until 1687, when a Venetian shell hit the gunpowder the Ottomans had stored inside.
