THE DEEPEST HOLE

True story. In 1970 a team in Russia started drilling the deepest hole ever made by humans. It took 25 years. They reached 12,262 meters down. That is deeper than the deepest part of the ocean. You will dig the same hole now, and learn what they found.

For scale: Mount Everest is 8,849 m TALL. This hole is taller than Everest, only pointing down.
