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.'"
