Four regular red-backed cards and four blue-backed cards with circles on
their faces are shown on both sides. A person names one of the regular
cards and it is placed face down on a table or in a spectator's hand. Then,
magically, one of the circles disappears leaving that card blank faced.
However, when it is turned over, it's back has tranformed into the matching
face of the card on the table or hand. When the card on the table or hand
is turned over, it's face has changed into a blue back with a cricle on
it. This is typical Frostian magic with multiple climaxes and is not difficult
to do. At the end, you are left clean and everthing can be examined. Also,
this is an instant reset and therefore, perfect for walk-around magic.
