From a wooden box engraved with The Eye of Horus you remove the effigies of three Egyptian Queens. Each one is a different colour: white, grey and black — representing respectively Meritamen, Hatshepsut and Nefertiti. These are handed to a spectator, along with a small hand-finished sarcophagus. You invite the spectator to place any mummy into the sarcophagus, close it, and place the sarcophagus on the table.
The spectator places the other two mummies back in the box so that there is no clue to the identity of the mummy placed in the sarcophagus. You identify the Queen and reveal the colour without touching the sarcophagus, or even going near it
