Not sure what the ship in the title refers to… might mean chip…
A cup, tray and token are introduced. While the magician turns around a spectator places the token on the little tray and remembers which side of the token is facing up. He then covers it with the cup and secures it all with rubber bands. Magician holds the ensemble to his forehead where it serves as a transmitter to read the spectators mind. He names the correct side facing up. This can be repeated as often as wanted. Cup and tray are entirely opaque and there is no visual clue of any sort nor any additional outside props.
It is typical for Magiro’s clever thinking. The token could be customized with a vinyl sticker on both sides.
Original German instructions are included as well as a short English write-up to illustrate the handling.
