The team makes a new moai so as not to damage the existing ones on the island. The moai were carved from volcanic tuff (compressed ash) in Rano Raraku island crater. NOVA's moai will be made by pouring concrete, mixed with island soil, into a fiberglass mold. The mix is dried in a curing pit and then freed with the help of a chain saw.
Says Van Tilburg of the creation: "It's a wonderful thing to see this thing being born like this."
