By size · Order from shortest to longest.

1. A ten-pin bowling pin 38 cm

   Pins are coated in tough plastic and weigh just enough to scatter dramatically yet stand back up reliably.

2. A small recreational sailboat 9.4 m

   Modern sails work like vertical wings, generating lift that lets boats sail faster than the wind itself.

3. Mount Olympus, Greece 2.9 km

   Mythical home of the Greek gods, its peak was not officially climbed by humans until 1913.

4. Mount Fuji, Japan 3.8 km

   Though it looks serene, Fuji is an active volcano that last erupted in 1707, dusting distant Tokyo with ash.

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 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.
