I can't remember the name but there is a term for the sensation that a Ouija board thingy is moving on its own and not from the motion of the persons hands. Perhaps showing her that it is a well understood effect she just might accept that it wasn't moving on its own.

You could also try Penn and Tellers Bullshit episode on Ouija Boards, they do some tests on people about the board and show how the people are doing the moving. Stuff like rotating the board and showing how without being able to see the letters the people make it same complete nonsense.
