There's an island in Argentina that can actually move and rotate by itself. It's called El Ojo. But how can an entire island move? Because the island is made of floating soil and thick vegetation, and it isn't attached to the bottom. Wind and water currents then push the whole island around, making it slowly rotate. But when you first see it from above, you might think someone actually built it, as the island is almost perfectly round with a circle of water around it, making it look like a giant eye. It's around 118 meters wide, and satellite images show El Ojo has existed there since at least 2003. But the strangest part, nobody knows exactly how it formed.
