You show a beautiful black Chinese coin with gold markings, and rub it gently with your fingers. All of a sudden, the coin changes colour to a bright red! A visual and lightning- fast colour change. You can repeat this over and over again: the coin changes from black to red and from red to black as if having the time of its life. Then, completely unexpected, you take it one step further. Suddenly, the coin is blue. On both sides! The looks of disbelief will not be far away. Let someone take the coin out of your hands, and show those to be completely empty as well. Visual magic at its best. Moreover: this is really easy to perform, without complicated or insurmountable manipulations.
