The Alpha Tunnel T-117

The magician exhibits the Alpha Tunnel, a square tube which represents a passage into the fifth dimension. A solid panel in inserted through the tunnel, completely blocking the passage. Up until the last moment, the spectator can see that the panel is in place. With absolutely no false moves, the magician drops a solid metal ball completely through the tunnel, and instantly the spectator can plainly see that the tunnel is still blocked and you can hand out all the props for examination. Even when the Alpha Tunnel is completely blocked by a solid panel, a ball penetrates through the tunnel, leaving no clue to the mystery. Very good condition.
