    To build your own sun scope, get a carton and cut a hole in one side, big enough to poke your head through. Paste white paper on the inside surface that you will be facing. Then punch a pinhole into the opposite side high enough so that the little shaft of light will miss your head. For a sharper image you can make a better pinhole by cutting a one-inch-square hole in the carton, taping a place of aluminum fold over this hole, and then making the pinhole in the foil. Finally, tape the box shut and cover all light leaks with black tape.
