Magician shows six feather plumes all different colors. He rolls up a sheet of thin cardboard or newspaper into a tube then one by one pushes the plumes through the tube. Each one changes color as it goes through the tube. At the end, the magician unrolls or crumples the tube and throws it to the audience. You will receive all the feather plumes needed for this effect, plus the necessary gimmicks.
Any piece of thin card or newspaper can be used.
