A compact metal plaque, the size of a playing card, is presented to the audience. It features three holes in vibrant colors: yellow, green, and red. A spectator is invited to select two bolts and two nuts to secure them in any two of the holes, leaving one hole open. Meanwhile, an envelope sits on the table, which has been there throughout the performance.

When the plaque is revealed from the envelope, it astonishingly displays two bolts fixed in the same holes chosen by the spectator! The envelope is completely empty, allowing the magician to unscrew the bolts to verify their authenticity. This effect comes with two metal plates, a question mark for the envelope, and all necessary bolts to perform the illusion.

This trick is straightforward to execute, showcasing your remarkable mind-reading abilities. Video instructions are included for guidance.
