Tenyo Super Phanto Block (T-74) 1976
Takuya Yoshizawa

Two tubes are displayed, large and small – each has a hole on opposite sides, so that when the small tube is inserted into the larger one, a metal rod can be thrust through the holes preventing any movement. A spectator is invited to hold each end of the bar. The magician gives the magic word and taps the top of the tubes. The inner tube passes through the bar and drops onto the table. Everything can now be examined by spectator ! Nothing is hidden or added at any time !
ONLY Tenyo´s version has the “locking” mechanism that makes it possible to let it be fully examined by one spectator who will not find out the clever secret ever.
