Card Warp - Ultimate
Two Cards are shown, let's say the red Seven of hearts and the blue eight of hearts.
The Red seven is folded in half and the blue eight is folded lengthwise.
The seven is placed inside the eight and turned back inside-out.
The eight is passed through the seven and magically changes into the seven!
Now the eight is the red card folded in half and the seven is the blue card folded lengthwise.
The eight is now placed inside the seven and turned inside-out.
The seven is passed through the eight and flips inside-out.
Now you see the back and the front of the seven at the same time.
The card is left in this position and ripped in half.
The half is turned over to reveal that the seven and eight have merged!
