Build a Kid's Periscope Plans
These are plans for making a spy periscope for the kids.
Mention of periscopes is quite common
in the reports from European
battle fields; such a device in a simple
form can be made easily by boys who
have fair skill with tools. The illustration
shows a periscope which may
be used for play, and has other practical uses as well.
In a store or other
place where a person on duty cannot
watch all parts of the establishment
such a device is convenient in that it
will reflect persons entering the door.
As a toy or for experimental purposes
the periscope shown has many possibilities,
and will appeal to youngsters.
It consists of a square box, 18 in.
long, open at the ends. It is 3½ in.
wide and made of wood, .375 in. thick.
A mirror is fitted at an angle of 45° near
one end of the box or tube, as shown in
the sketch. The front of the mirror is
opposite a three-cornered opening in
the box which extends across one side.
The opposite end of the tube is also
fitted with a mirror in the same manner,
except that the front of the mirror
faces to the opposite side of the box
at which there is also an opening.
