Indiana Jones is searching an underground tomb for the Eye of Klaatu. He comes across two seemingly identical potential artifacts: a jewel in the center of a heavy steel framework. One is the Eye of Klaatu; it has a diamond in the center. The other is a fake and has a cubic zirconia in the center. Cubic zirconia is twice as dense as diamond, but the steel frame is so heavy that Indy can’t tell by holding which one is heavier and he can only carry one out. Indy finds a fallen wooden beam that can act as a straight ramp, so he rolls both artifacts down the ramp from rest at the same time and object A reaches the bottom first. Which one is the true Eye of Klaatu
