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 dentist-approved tooth brushing session 2 min

   Studies show most people actually brush for about 45 seconds while believing they've done the full recommended time.

3. Yuri Gagarin's entire Vostok 1 spaceflight 108 min

   The first human spaceflight was a single orbit — and Gagarin ejected and parachuted down separately from his capsule, landing in a potato field.

4. James Cameron's film 'Titanic' 3.2 h

   The movie runs longer than the actual sinking it depicts — the real ship went down faster than you can watch it go down.

5. The Woodstock music festival of 1969 2.8 days

   Billed as '3 days of peace & music', it overran badly — Jimi Hendrix closed at 9 am on Monday to a field mostly littered with sleeping bags.

6. An African elephant's pregnancy 1.8 years

   The longest gestation of any land mammal produces a 100 kg calf that can walk within hours — and is looked after by the whole herd.
