Let your imagination leave this world and travel to other planets! Study an actual moon rock collected by astronauts from Apollo 17 and grasp the properties of aluminum-lithium alloy. Launch a rocket to explore air pressure, climb into a space capsule and blast into outer space.
From the German word for ball, the kugels are giant spheres of granite that depict features of planet Earth and the Moon. The big one (Earth) weighs 29 tons and rolls with only 33 pounds of pressure per square inch—that’s less pressure than your faucet at home! The Kugels are mounted in...
