Will is working on this tutorial right now.

The Template for the ultimate periscope is ready and right here: The Template

This is a fun cardboard project. I show you how to make it step-by-step and I give you the template so you know exactly the size of each piece.

And.... you can make your periscope using glass mirrors (I have a link) or you can make it using mirrored cardstock or mirrored paper which is easier to do. I have links for the mirrored paper too.

The thing that makes this periscope "ultimate" is that you can extend or contract it by a foot and the top portion which I call the turret can be rotated.

I also have a project where you make a simple and easy periscope. You can check that one out right here: The easy periscope

Parts and Materials:

• Some corrugated cardboard ( 1 medium box should be enough)
• Glue or hot glue
• Knife or xacto knife
• glass mirrors or mirrored cardstock

Mirrored Cardstock

If you are unfamiliar with how a periscope works this picture gives you a good understanding. You look in the bottom left and the arrows show your line of sight. You look at the bottom mirror which bounces off the top mirror then out the perioscope. Two mirrors are the working aspect of a periscope.

Let's Build it

There are four parts we make for the periscope. We start by making the base.

There are seven pieces that make up the base of the periscope. This diagram shows you the pieces and how they are assembled together.

Start by gluing together A,A, B, and D.

Then install the mirrored section (F). We install it now because it would be more difficult to install later on.

Finish off the assembly by gluing on parts C and E.

About the mirrored section

Cut your mirrored paper to the size of Part F.

And glue that mirrored paper to Part F. But, and this is important! Use only a very small amount of glue. Just several dots around the edges. This is because if you use a lot of glue it will cause wrinkles in the mirrored paper. Wrinkles will distort your views through the periscope.
