Before the NOVA crew attempts to erect an obelisk, they will try to move a big stone. Modern-day builders would employ a crane and a flatbed truck to move a heavy stone like this one. But an ancient Egyptian relief painting shows long lines of men pulling a monumental stone across land.
The NOVA team, committed to raising an obelisk as the early Egyptians might have, rely heavily on the same energy the pharaoh's engineers employed: the collective power of human muscle.
