Giant Stone Balls of Costa Rica
Laborers hacking and consuming the thick wilderness of Costa Rica to clear a territory for banana manors in the 1930s unearthed some staggering items: many stone balls, huge numbers of which were impeccably circular. They differed in estimate from as little as a tennis ball to a bewildering 8 feet in measurement and measuring 16 tons! In spite of the fact that the considerable stone balls are obviously man-made, it is obscure who influenced them, for what to reason and, most confusing, how they accomplished such round exactness.
