The greatest penetration trick ever invented! You place a ring (which may be borrowed) into a crystal casket and close the top. The box is covered with an empty tube and a magical cleaver (a small sword) is inserted into the top of the tube. The cleaver is magically pushed down through the crystal casket and through the ring. When the tube is removed the sword is seen to be through the ring inside the casket! A new principle is used that makes this effect a real mind-blower. After the trick everything (yes, everything!) can be passed out for examination.
