1. A single grain of table salt 60 µg

   Salt crystals are near-perfect cubes because sodium and chloride ions lock into a rigid lattice — about a million grains fit in one cup.

   Rice feeds more than half the world's population, and farmers cultivate over 100,000 distinct varieties of it.

   World Cup balls are tested in wind tunnels; the 2010 'Jabulani' was so smooth that goalkeepers complained it swerved unpredictably.

   The largest beaver dam ever found, in Alberta, Canada, stretches about 850 meters and is visible from space.
