this is a photo of a cool physics demonstration for sierra (left) and rachel (right), 2 homeschoolers in new mexico. there's a piece of transparent silk stretched on a frame above them (they are lying on the floor). there's a heavy silver bocce ball sitting on the fabric in the center curving the "fabric of space" (i'm reflecred in the silver ball). then voila, when the lighter ball is tossed onto the curved fabric.. from their perspective it "orbits" around the silver one... but when you look at it from the side you see that the fabric is simply curved... get it? this is such a great picture cause it captures an aha moment ..when you see or understand something from a different point of view... try it!
