Bored? Un(der)employed? A gang of loonies who believe that a mystic seer's revelation that the Great Pyramids were actually water-pumps will give you $50,000 to quarry, move and stack some big-ass hunks of limestone. You get to keep the stones.
To receive the $50,000 the above tasks must be completed in the manner described by traditional Egyptologists, and the results must be of the same precision as the original casing stones. No steel hammers, steel chisels, or other steel tools. No chains or nylon ropes. No forklifts or heavy power equipment or internal combustion engines in any part of the process. Only use the tools and stone moving methods described by traditional Egyptologists. This allows the option to use up to 100,000 slaves, workers, or taxpayers if you want to.
