Holding up the Earth

We went to a new education center in town today. We had a 45 min. presentation on the earth's water, earthquakes, volcanos, and weather. It was very interesting!! This is just a large white ball suspended from the ceiling, but there are 4 projectors shining on it. It looks and circulates just as the astronauts would see it from space.
There are only 79 others in the world. Pretty cool!!!!
