Submarine periscope

To Use Your Periscope in the Submarine
In the center of the conning tower cut a circle a little bigger than your periscope box. See Picture.
To make a periscope mount, take a piece of heavy cardboard. Cut a circle a little bigger than the one in the conning tower.
Set the periscope box on this circle and draw around the square box. Cut out.
Remove one mirror and slip the periscope into this circle mount. Replace mirror.
Put one end of the periscope through the hole in the conning tower, so that the mount is outside the box.
You can add all kinds of finishing touches. You can make a control panel on the inside of the conning tower. You can add an anchor, and even paint on a name.

Make Periscope
Stand box up with the “T” at the top. Place your triangle pattern along the bottom edge of the box, folded edge slanting upward. See Picture.
Draw a line on the box along the slant. Cut a slit on this line.
Around the corner from the top end of the slit, cut a window big enough to look through.
Place the triangle pattern at the top of the box, on the same side as the lower slit, folded side slanting down. See Picture. Draw a line along the slant. Cut a slit on this line.
Around the corner from the top slit draw and cut out a top window. This window must be on the opposite side of the box from the bottom window.
You will need mounts for your mirrors. Draw and cut out two pieces of cardboard as wide as the box and a little longer than the slant of your triangle pattern. Glue one mirror to each mount. See Picture.
Slide one mirror in the lower slit, looking-side up. Slide the other mirror in the top slit, looking-side down.

How to make a periscope

Make a Real Periscope

a small piece of paper
a piece of tablet back or thin cardboard

Yon will need to know which end of your long box is the top. So mark a “T” for “top” at one end.
To make an important pattern that you will need, trace a square exactly the same size as the end of the box on a piece of paper. Cut out the square. Fold the square to make a triangle. See Picture.
