The series premiere travels to Cairo explore the Great Pyramid of Giza, which is more than 40 stories high and the width of 10 football fields. The 200 levels of stone weigh more than six million tons, with each individual block the size of an SUV. Nothing in the world compares to it. The city of Memphis, Tennessee tried to recreate its own Pyramid in 1991, but immediately had issues with flooding and closed its doors in 2004. Clever engineers eventually embraced its watery past and reopened the building in 2015, featuring an aquarium on its bottom floor.
