another way I've discovered to use this prop, and it has blown many minds already...is that I tell
them it is a miniature brain scan...I force the card that appears in my wow 2.0...I tell them to
hide the card in their pocket or somewhere...then I gently rub my wow lightly on their head, and
while doing so I hit the right place to make their card appear. So when I bring the brain scanner in
front of them they see the image was taken right out of their brain!
