The performer displays a solid metal rod, and a metal ring. Both can be examined.
He now introduces a cabinet, open on top, with a cut out front, and a sliding panel to cover the front. The front is covered, and the rod placed through the 2 slots on the sides of the cabinet. It projects out of the cabinet, and both ends are clearly in view.
The ring is now dropped into the cabinet. The front panel is removed, and the ring is seen to have penetrated onto the centre of the rod. The rod with ring is lifted out of the cabinet, and both ring and rod can be examined again.
Made in Wood, painted in bright enamel colors, the apparatus measures approximately 5.5″ square and 8″ high.
