You show your audience a large white card with a single big black dot on one side. You turn the card over and find four dots on the other side...Turn over the card again and there are now THREE dots!! Turn it over again and find SIX dots! You explain that by covering some dots with your fingers and not covering others it changes the way the dots appear... Your audience THINKS they understand the trick until you turn the card over one last time. When you turn the card over one last time, like magic, EIGHT dots appear!!
