1. One ounce of gold can be stretched into a wire so thin that it is only five millionths of a metre thick. That thin wire could stretch over a distance of 80 kilometres.

2. One ounce of gold (that’s about the size of a quarter) can be hammered into a thin sheet that could cover about nine square metres.

3. Gold leaf can be as thin as three billionths of a centimetre. That means a stack of 7,055 sheets would be no thicker than a dime.

4. All the gold mined in the history of the world would fit into two Olympic sized swimming pools.

5. The visors on astronaut’s space helmets have a coating of gold that is so thin they can still see through it. That thin layer is able to reduce glare and heat from sunlight.

6. Oceans have more gold than anywhere else in the world. It’s too expensive to be worthwhile extracting it—yet.

7. The largest gold nugget ever discovered is called the “Welcome Stranger”. It weighed 78 kilograms, and was found in Victoria, Australia in 1869.

8. In the Aztec language, gold is called teocuitiati. That means “excrement of the gods.”

9. The Federal Reserve Bank in New York has the largest store of gold in the entire world. It is contained in a vault 25 metres beneath the street. The gold bullion is worth $147 billion (probably more in these days of rising prices). Luckily, Manhattan’s bedrock is strong enough to support the vault, the vault’s door, and the gold.

10.  Just one out of every one billion atoms of rock in the Earth’s crust is gold.
