Explore the mysteries of the ancient pyramids of Egypt, then be an Egyptologist with the 3-D pyramid puzzle and guide included in the set. Also includes This Old Pyramid. Join Egyptologist Mark Lehner and stonemason Roger Hopkins as they test out the many clever, and sometimes bizarre theories of how the ancient Egyptians built their pyramids. It's the ultimate hands-on construction as a team of Egyptian craftsmen build a real pyramid in the shadow of the Great Pyramid of Giza. Then tour the hidden tombs and passageways and view stunning computer re-creations of the ancient pyramid sites. Then... solve the riddle of how to build your own pyramid. It's harder than you think!
