Yahoo is actually reporting that a physics professor at the University of Amsterdam has discovered that pouring water on the sand in front of a sled carrying a large stone block would make it easier to pull and this is how they built the pyramids! My god, what will they think of next? But then Cecil B. Demille had that figured out in The Ten Commandments! Remember 'ol Yoshabel greasing the stone blocks being pulled and getting her sash stuck? "Help me Moses!"
