  1. 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.

  2. The Wright brothers' first powered flight 12 sec

    The 1903 flight covered just 36.5 metres — shorter than the wingspan of a Boeing 747. Within 66 years, humans were on the Moon.

  3. Cooking a perfect soft-boiled egg 4.5 min

    At high altitude it takes noticeably longer — water boils below 100°C up a mountain, which is why mountaineers complain about their eggs.

  4. Holi, the Hindu festival of colours 2 days

    It opens with the Holika bonfire at night and erupts into colour-throwing the next day — the powders were traditionally made from flowers and herbs.

  5. Voyager 1's journey from launch to interstellar space 35 years

    It carries a golden record with greetings in 55 languages and Chuck Berry — and it still phones home daily on a 1970s 8-track-era computer.

  6. The Romanov dynasty's rule over Russia 304 years

    It began with a 16-year-old reluctantly accepting the throne in 1613 and ended 304 years later with Nicholas II's abdication in 1917.
