The Chinese Linking Rings (The Secret Key)
Solid steel rings clatter together, meld through solid metal into chains of three and four, and detach with effortless grace.
An assistant enters an upright wooden cabinet. Two steel blades divide her in three, and the center box slides sideways - a gaping hole in her torso.

A female assistant steps into an upright cabinet. Her face, right hand, and left foot remain visible through small circular apertures. The magician slides two large steel blades through the cabinet, apparently slicing her waist and abdomen. The entire midsection of the cabinet is then slid horizontally out of the frame by over 12 inches, leaving a vast empty void where her torso should be. She still smiles and wiggles her fingers.
The illusion is an optical masterpiece created by British magician Robert Harbin. The assistant does not stay in the center; she turns her body sideways, contorting into a narrow vertical pocket running down the black-painted left side column of the cabinet.

The cabinet is engineered with optical deception: the exterior is brightly painted with decorative geometric borders, but the back-left corner features a matte black beveled alcove that looks half its actual depth.
Once the door closes, the assistant turns her torso 90 degrees, pulls her hips completely into the hidden left cavity, and presses flat against the interior wall. The two steel blades pass cleanly through empty space in front of her body.
The magician pushes the center box sideways. Because the assistant’s torso is tucked in the side column, the box moves out completely empty, showing daylight straight through the midsection.
The note about holding the cards at a 15-degree downward angle completely changed the Marlo Tilt for me! I was holding it level and kept flashing the wedge.
Clear and honest breakdown. Most YouTube tutorials rush through the Double Lift turnover, but explaining the book-page rotation made my handling 100% silent.
