1. A grain of table salt 0.5 mm

   Each crystal is a near-perfect cube because salt's atoms stack in a rigid cubic lattice.

2. A standard house brick 22.5 cm

   Fired clay bricks have been made the same basic way for over 5,000 years, outlasting the empires that baked them.

3. A great white shark 5.2 m

   Great whites can detect a single drop of blood diluted in 100 litres of water from hundreds of metres away.

4. The RMS Titanic 269 m

   When launched she was the largest moving man-made object on Earth, longer than most city blocks of the day.

   The first person to swim it, in 1875, took nearly 22 hours and slathered himself in porpoise grease for warmth.
