I originally found this on the Middle School Science Yahoo Group website and was so amazed by it.  It is SO cool.  My husband couldn’t see it.  Jackie looked at and I asked her if anything was moving and she said no..she’s only 18 months  The power of optics is so cool. Enjoy.  I still can’t believe this isn’t moving.  To see more optical illusions go to Might Optical Illusions (awesome site).  Teachers this would be a cool site to talk about the importance of not always trusting our eyes
