How To Make Periscope

What is a periscope:

an apparatus consisting of a tube attached to a set of mirrors or prisms, by which an observer (typically in a submerged submarine or behind a high obstacle) can see things that are otherwise out of sight.

For the making of a periscope we need:

  • A cardboard piece (8inch by 12 inches)
  • 2 pieces of mirror (2×2inch)
  • A Glue gun
  • Scale
  • Scissor and  cutter blade


  • Take a cardboard piece 8 by 12 inch
  • Draw lines according to template
  • Take both mirrors and paste them vertically on a 45-degree angle facing the shiny sides each other   (on the section 1.5 inch)
  • Then cut out rectangles in front of the mirrors and we will fold all these sides and make a cuboid then we paste it
