Here are some helpful videos. That explain the process. When you make the camera you need two cardboard tubes, duck tape, masking tape, a pin, tin foil and Grease free paper. first you get the long tube and stick the grease free paper on with the masking tape, you the attach the short tube (which will be used as the view finder) to the short tube with the duck tape, once you have the base you attach the tin foil and use the pinhole to create the lens. THEN YOU ARE DONE !!!!!!!
