1. A grain of rice 7 mm

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

2. A wooden utility pole 18.5 m

   Most are pressure-treated with preservatives so they can stand outdoors for 40 years or more without rotting.

3. The Statue of Liberty (heel to torch) 47 m

   Her copper skin turned green over decades as the metal oxidised; she was originally a shiny reddish-brown.

4. The Leaning Tower of Pisa 58 m

   It began tilting during construction in the 1170s because of soft ground, and engineers only stabilised it in 2001.

5. A giant sequoia (tallest) 89 m

   These trees can live over 3,000 years, and their thick bark resists fire that clears competing plants away.

6. The Kiel Canal, Germany 98 km

   The world's busiest artificial waterway, it lets ships skip the long, stormy voyage around Denmark.
