Surveillance Operation - Build a periscope

URGENT TRANSMISSION
STATUS: UNRESTRICTED
SUBJECT: MAKE A PERISCOPE
SECURITY LEVEL: 3 [LOW]
This periscope is ideal for reconnaisance missions. Use it to spy round corners or over the top of walls, without being spotted.
KIT:
Two empty and clean Milk of Fruit cartons
Sticky tape
Scissors
Two Small mirrors at approximately 7.5 cm square
Ruler
Protractor
Pencil


Step 1

Carefully cut off the top and bottom from each of the cartons.

Step 2

Place the two cartons end to end before taping them together so they create long cylinder.

Step 3

Position the cylinder upright on a flat surface.

Step 4

Draw a 5cm square at the end of the cylinder before cutting it out. Draw another 5 cm square opening at the end of the opposite side of the cylinder, before then cutting it out.

Step 5

Using the protractor, calculate 45-degree angles on the sides adjacent to each square. Position the centre of the protractor on the corner, next to one of the side with the square gaps. Use a pencil to mark 45 degrees on the side of the cylinder. Draw a line from the corner of the cylinder to the mark using a ruler. Repeat this step for the corner next to the other square gap.

Step 6

Cut two 0.31 by 7.5cm slots along the 45 degree lines at the corner of the square gaps

Step 7

Insert the mirrors into the slots. Ensure that the reflective sides of each mirror face each other, before using more tape to hold them in position.

Step 8

Hold the cylinder upright and look into one of the square openings to view around corners or see over things taller than yourself.

Step 9

Decorate the periscope with camouflage so it blends into the environment around you. If you’re planning to spy from behind trees or bushes, then add foliage such as leaves and bushes.

A FINAL WORD:

Good luck with your surveillance operation. And remember to keep a look out at all times - Ogel Drones could be watching YOU! Alpha Team Agents scramble!
