By size · Order from shortest to longest.

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 grain of rice 7 mm

   Rice feeds more than half the planet, and a single plant can yield thousands of these grains.

3. A standard paperclip 3.2 cm

   The familiar looped design, called the Gem clip, was never patented and has barely changed in over a century.

4. A Bengal tiger (body length) 2.1 m

   A tiger's roar can be heard up to three kilometres away and carries frequencies low enough to paralyse prey with fear.

5. The Brooklyn Bridge (total length) 1.8 km

   When it opened in 1883, a stampede fearing collapse killed twelve people; a circus later marched elephants across to prove its strength.

6. The Strait of Gibraltar (narrowest width) 14.4 km

   It is so narrow that on a clear day you can see Africa from Europe across the water.
