Box Monster by Nathan Kranzo

Make cards move at will.

IMAGINE : The spectator selects two cards out of the deck-- there are no forces. With no funny moves, the cards are placed back in the center of the deck. The deck is then placed back into the box. The box is closed. Nothin' fancy.  Yet .
With no false motions, the card box visibly  opens itself  and one card is seen to  slowly, visibly rise  up out of the deck. Your hand grips the card gently, then pulls it out of the deck. The card is slowly turned over-- done. You've  nailed  card number one.

The cards are then held in your hands. The spectators eyes are fixed on your hands like a hawk. You bring the cards down to the table and begin to spread the cards slowly from right to left. 

One card begins to slowly  move out of the spread , towards the spectator -- while on the table. You've never seen  anything  like this. And your spectators haven't either-- it's downright eerie.
