Corner Reflector Corner Reflector See yourself as others see you. The number of images depends on the angle between the mirrors. When you set the hinged mirrors on top of a third mirror, you create a reflector that always sends light back in the direction from which it came. Plastic mirrors are best, since there is less danger of breaking the mirror or cutting your fingers.
Plastic mirrors are available at plastics supply stores and can easily be cut to any size.
Glass mirror tiles are readily available but are not as safe. You can cut the plastic with a fine saw, such as a hacksaw, or score it with a utility knife and then snap it off. Once you have the three mirrors you need, use the duct tape to tape two of the mirrors together along one edge. Put the tape on the back side of the mirror, making a hinge that opens and closes easily. Be sure the mirrors can move freely from 0 degrees to 180 degrees.
