        Levers: Raising the Moai on Easter Island

        A team of archaeologists and engineers tests one theory of how the ancient peoples of Easter Island (Rapa Nui) might have transported a massive statue, called a moai, from cliff-top quarry to coastal perch and then raised it to an upright position. Levers are simple machines that can help amplify lifting force. As the scientists and local participants discover, even with the mechanical advantage of a lever, the challenge is decidedly difficult and extremely time-consuming. Video segment adapted from NOVA.
