JL has brought back this classic of magic in a nice quality, affordable version.  Instantly show the a beatiful, shiny array of 6 different color foil ribbons.    If you produce the item from your palm, that's enough of a trick right there!   But, then the real magic happens.  You have the audience pick a number between 1 and 6, and no matter what they chose, you magically change the array of ribbons to all one color, matching their number.   Colors are random.
