Rib-Blok by James Swoger, Mark Jacobs

Rib-Block was invented by Mark Jacobs and built by John Snyder c. 1942. Then James Swoger and more recently Jay Leslie. This is a James Swoger’s version.

While this effect resembles the old block and frame effect wherein the block and frame have a hole through them, through which a ribbon is threaded and block removed from frame while ends of ribbon are held by spectators, there is a vast difference in the method used since it is possible to pass both the block and frame before and after presentation, and to immediately repeat the effect without any false moves.

Effect: One of the “most clean” penetrations ever! A three and a half inch die is examined along with a corresponding red and black open bodied box. A length of ribbon is also handed to a volunteer to pull on, proving that it is solid. The ribbon is threaded through both sided of the box showing that it passes through. The ribbon is removed. The die is set in the box so the hole running through it lines up with the holes in the box. The ribbon is passes through the first hole, through the die and out of the second hole. Hocus Pocus!!! the die is removed from the box apparently melting through the ribbon. The ribbon is seen passing through both holes in the box.

• No wax is used
• No extra pieces of ribbon
• The die is completely solid
• Can be seen from the stage
• Rounded corners on the die and holes in the box
