Electricity has always been in the domain of the Wizard,
along with chemistry and magnetism and a whole lot of things we
call today "science." Run your fingers over the surface
of the glass globe and the trails of colorful static electricity
will follow them. Press your whole palm against the globe and it
looks as if all the power is being drawn into your hands... a
useful idea for setting the stage.
Now have a Tarot or regular card chosen from a deck by a
third party. You hold hands with the "mark" over the
electronic crystal ball and ask the "mark" to stare
into it for clues about the chosen card. In a few moments, the
electrostatic lightning forms up like this:
The third party confirms that the chosen card was indeed the
Two of Hearts, or Seven of Wands, or whatever you are serving up
that day. Since you are making the gimmick yourself, YOU decide!
The electronic "crystal ball" comes from Target
($19.95) or Spencer Gifts, etc..
