Alex Elmsley's Dazzle

A trick using five red-backed Jokers. One of them is set aside, and replaced with a blue-backed Joker. The other red-backed Jokers magically change color to match the blue stranger. One of the blue-backed Jokers is removed and replaced with an orange-backed Joker; the other Jokers in the packet turn orange as well. This process is continued, as the packet of Jokers is caused to go through a bewildering number of color changes, from orange to yellow to green, etc., finally culminating with a change to nothing but faces on all sides, leaving a packet of five double-faced Jokers!
