    The rubber hand illusion is a good way to make someone throw up. The illusion becomes very disconcerting for some people since they know the hand isn't real, but their sense of touch keeps telling them otherwise.

    This is great. I may do the finger-in-the-eye/binoculars activity with my "How things work" class when we cover optics. I have ping-pong balls from last term... I'll have to sacrifice one to try this at home.
