Because the rocks often sit motionless for a decade or more, the phenomenon remained a curiosity, until 2014. Scientists, in what they suspected would be "the most boring experiment ever,” fitted 15 rocks with custom-built, motion-activated GPS units, waited a mere two years, and finally solved the mystery.

Bran Castle, Romania
