The mystery of the giant stone balls of Costa Rica in the Diqius Delta. These stone balls were clearly man-made, but their purpose, and who made them, is unknown. Most of these are made of granoduirite, a hard, igneous stone. Their size ranges from as small as a tennis ball to a huge 8 feet in diameter; weighing 16 tons, and its spherical precision and smoothness is of such a perfection that it would be impossible to re-create these without the use of power tools today.
