This is an investigation into the story and mystery of the enigmatic tube drills of Old Kingdom Egypt. A story that stretches across 150 years, from Petrie to Lehner to Dunn, this is an astonishing tale, with a startling and challenging conclusion!

A full length documentary, this has been in the works for a long time! I will release several 'addendum' videos on this topic. Please consider supporting UnchartedX for more work like this via the value-for-value model at !
