Mixed Up Card Frame

You show a large envelope with a prediction inside. A spectator selects a card. You claim that your prediction is a perfect match....

You open the envelope and remove a framed piece of clear plastic, showing the entire deck of cards, faces on one side and backs on the other! Not so amazing...but wait!

You then ask the spectator to hold their hand above the frame for just a moment. When they removes their hand, one of the face-up cards has turned face-down! Turn the frame over, one card is face-up...and it's the selected card!

• Very, very clever
• Self contained
• Mechanical
• Nothing added or taken away
