The original Shigeo Takagi’s routine is still available in Richard Kaufman’s wonderful book: The Amazing Miracles of Shigeo Takagi.

Effect: A wooden cup and wand are displayed. A small ball is produced from the end of the wand. The ball is vanished several times and repeatedly reappears beneath the cup. Then a large ball appears underneath the cup, but the cup is then shown to be solid. Then the ball is apparently pushed back in the cup. The cup is then unscrewed to show the ball inside! Must be seated to perform but can be adapted with some thought for stand-up work
