Effect: The performer shows 3 mummies of three different color (RED, BLUE and YELLOW) of equal size and shapes, plus a wooden coffin. He places them on a table. He then invites a spectator and hands him over the Mummies and requests him to place a Mummy of his choice secretly inside the coffin and put the coffin (lid closed) back on to the table. He is also requested to conceal the other two Mummies. The performer reveals the color of the mummy inside the coffin without either touching the coffin or going near the table.
Easy to do.
