๐Ÿ“ Where is it?

๐Ÿ“ Xi'an, China โ€” see it on the big map →

More than 2,000 years ago, people in China discovered a strange black stone called lodestone. It was a natural magnet, and it always pointed the same way โ€” towards the south. Clever inventors carved it into the shape of a spoon and placed it on a smooth plate. Wherever the spoon spun, its handle always stopped pointing south.

Later, people learned to magnetise a thin needle and float it in water, so it could spin freely and point north. That was the compass. For the first time, sailors could find their way even when the sun and stars were hidden by clouds.

The compass travelled along trade routes to the rest of the world, and it changed exploring forever. Ships could sail across whole oceans instead of hugging the coast. Without the compass, the great voyages of discovery might never have happened.

๐Ÿคฉ Wow fact!

The first compasses were spoons carved from lodestone, a natural magnet โ€” and they pointed south, not north.

๐Ÿง  Quiz time!

What did the first Chinese compasses point to?
