Borrow a bank note from the audience, Fold it in four, and slip it into the frame. Then slice it into three parts with two blades. You now slide out the middle section proving that the bank note is really in three separate pieces. Slide back the middle section, remove the blades, take out the bank note, and amazingly, it is unharmed. The bank note remains in view at all times throughout the cutting and restoration the audience sees everything.
