1. A grain of rice 7 mm

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

   Its glowing filament reaches around 2,500 degrees Celsius, yet wastes most of its energy as heat, not light.

3. A cheetah (body length) 1.2 m

   A cheetah's spine works like a spring, flexing so much that its stride can cover seven metres at full sprint.

   It held its neck high like a giraffe, possibly needing a heart of enormous power to pump blood up to its brain.

5. The Suez Canal 193 km

   It has no locks because the Mediterranean and Red Sea sit at almost exactly the same level.

6. The Trans-Siberian Railway (length) 9.3K km
