Creative Madnes: How to make a periscope?

Things needed:

Method :

Cut 2 holes on either side of the shoe box. (remember to leave 15mm space from the ends)
The holes should be on the opposite sides.
Paste the 2 mirrors on a 45degree inside the box on either sides.
Cover the box with the lid.
Decorate your periscope as you want.

Enjoy sneaking and peaking above the fence or wall.

Facts about the periscope-

A periscope is an optical device which allows an observer to see things which are beyond his or her line of sight.
One of the classical uses of a periscope is in submarines. Instead of needing to surface to see what is going on at sea level, the submarine can instead stay safely submerged under the water and extend a periscope to look around.
Periscopes are widely used in the military, but also in other fields, such as medicine and hunting.
Periscopes consist of a long tube which contains either mirrors or prisms.
The mirror or prism at one end captures the image and bends or reflects it so that it can travel down the tube to hit the mirror or prism at the other side, bending the image again so that it can meet the eye of the viewer.
If the tube is extremely long, magnifying glasses may be used to enlarge it so that the viewer can see clearly.
Periscopes can be portable, as in the case of the trench periscopes used in the First World War, or they can be fixed into a housing such as a tank or submarine.
In 1854 Hippolyte-Marie Davy invented the first naval periscope.
Simon Lake used periscopes in his submarines in 1902.
Sir Howard Grubb perfected the device in World War I.
Morgan Robertson claimed to have tried to patent the periscope: he described a submarine using a periscope in his fictional works.
The first periscope was made by Johann Gutenberg around 1450.
