1. 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.

2. The Gateway Arch, St. Louis 195 m

   Its elegant curve is a catenary, the exact shape a hanging chain makes, flipped upside down for strength.

3. 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.

4. The Millau Viaduct, France 2.5 km

   The tallest bridge in the world, its deck sometimes sits above the clouds that fill the valley below.

5. The River Danube (length) 2.9K km

   It flows through more countries than any other river in the world, passing four national capitals on its way.

6. The Great Wall of China (total length) 21.2K km

   Contrary to the popular myth, it cannot actually be seen from the Moon with the naked eye.
