  1. A lightning flash from start to finish 198 ms

    What looks like one bolt is usually several return strokes in a row, heating the air to around 30,000°C — five times hotter than the Sun's surface.

  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. The Isner-Mahut match, the longest in tennis history 11.1 h

    The 2010 Wimbledon first-rounder stretched over three days with a 70-68 final set — the scoreboard wasn't programmed to go that high and broke.

  4. The 1900 Paris Olympic Games 167 days

    Spread thinly through the World's Fair, the Games were so disorganized that some winners died never knowing they had been Olympians.

  5. A frilled shark's pregnancy 3.5 years

    At an estimated three and a half years, it's the longest known gestation of any vertebrate — embryos grow just over a centimetre a month.

  6. 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.
