Electric Periscope
 
"Alvin measured the mirrors, then cut a long piece of cardboard from the box in which his mother kept his best shirts.  The shirts he rolled into a ball and placed on the top shelf of his closet.  He rummaged through the cigar boxes until he found a roll of electrician's tape.  He folded the piece of cardboard to form a long, square tube, and fastened it with the tape.  The he cut slots, slantwise, in each end of the tube and slipped the mirrors into the slots.  In front of each mirror he cut a little window.  From the shelf over his bed he took down his small flashlight and taped it to one end of the tube.

For a moment he looked at the invention admiringly.  'Not bad,' he said. 'Not bad for a hurry-up job.'"
