Did you know that the Egyptians bored into granite rock with drills that turned 500 times faster than modern power drills?

And how about this?:
* Coin-slot machines
* Steam engines
* Speedometers
* Machine-cut optical lenses
* Screen projectors

Did you know that Egyptian dentists worked with cement fillings, dental bridges… and inserted artificial teeth?

That William Deiches found working diagrams in Tutankhamen’s tomb (1545 BC) which helped him to build real model plane that flew?

That Egyptian doctors performed pregnancy tests, determined the sex of an unborn child, fed nourishment through tubes, and fitted artificial legs and hands? That they used anaesthetic and sophisticated instruments to perform bone and brain surgery?

What about old Egypt’s mysterious moving walls, automatically flashing lights and lamps that shone century after century, non-stop?

And how were sound waves used to open doors in ancient Karnak, Abydon and Thebes?
