How Big Were They?
by Dennis Gaffney

Between A.D. 1000 and 1600, the people of Easter Island, a small island isolated in the vastness of the Pacific Ocean, carved about 900 massive statues from an ancient volcano. These austere-faced giants, called moai, still stand, their backs turned to the sea.

It's clear that each moai was difficult to move over the island's hilly terrain—but how much do the largest stones weigh? In this NOVA game, you can find out by comparing the weight of the largest moai to a herd of elephants.
