I have know Fantasio for many years and admired his quality products, this one is real easy to do and fools even magicians who know the original color changing lighter, this one is based on an entirely different method and it easy to do. The magician shows a regular black pen which writes. A BIC lighter which lights. He places the lighter in the palm of one of his hands and closes it turning the fist back up. Using the pen as a Magic Wand he waves it over the closed fist and then he pushes the lighter with the pen out of his fist. As a miracle, the BIC lighter has now changed color. The magicians hands are empty aside from the pen. Supply your own BIC lighter.
