Mental Photography Card Trick
You show what a deck of cards looks like before they are printed. You clearly show them blank on both sides. Then, you cut a card but only the face is visible. Then the back of a card shows up. Suddenly the entire deck appears to have printed itself. All the cards are shown on fronts and backs! With just a simple cut the entire deck reboots itself like a hard drive and goes completely blank again! A visual stunner to say the least.
