Process of making

The materials used for the making the device:

+ Nails

+ Strings

+ Four Mirrors

+ One transparency sheet

+ Small blocks of plywood

+ Cut the blocks of plywood to desired lengths
+ Nail the plywood to the "top", "body" of the device, and transparency sheet together
+ Tie the two mirrors to one side of the device using string, but not tightly, so as to allow the mirrors to be opened

+ Tie the other two mirrors to another with strings, also not tightly
+ Test to see if the mirrors could be opened

+ Nail the plywood to both sides of the device, so as to prevent the mirror from slipping down when it is being held up
