Introduction: PVC Periscope

My son came to me with an idea to build a periscope. He had found a simple project in a book which used a milk carton and two mirrors. We had a couple of mirrors, but no milk carton. So, the Dad said: "We are not going to build this toy periscope, we are going to build a real one!". 
I bought a couple of 3" PVC elbows ($2.39 ea., http://www.homedepot.com/h_d1/N-5yc1v/R-100346018/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053&superSkuId=202905035) and a 2-ft. PVC pipe ($5.44, http://www.homedepot.com/h_d1/N-5yc1v/R-202018043/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053)
I had already a couple of 3" square mirrors from Michaels (sorry, no link here).
Then I cut two slots in each PVC elbow using Dremel Multipurpose Bit 561 (good for plastic and wood). 
The rest was easy: adjust the mirrors so they are at 45 degrees and make sure you see through the periscope. Then fix the mirrors using a glue gun.
The periscope is ready!

AWESOME instructable,

I have one question though,

I want the other end to look DOWN.
Want to make it for a little cousin of mine, who tries to jump up onto a wall (on the first floor) to look down at who has come at the door.

So, I want to fix this besides the wall and she should be able to see who is standing down without needing to get so high up (it is a bit dangerous as well, when she jumps up)

Add another mirrored joint to the end

Why the need to cut the elbows? The 3 inch mirrors should fit. Could i use something inside to keep them at the correct angle?

because a 3 inch square is bigger than a 3 inch circle

draw a 3 X 3 inch square then draw a 3 inch circle and place them on top of each other to see how it works

Great Instructable!

So many thanks, my first choise to serch this proyect was Instructables and i find it, this will be tomorrow homework to my cousin.

This is exactly what I was looking for. Are there any plans in the future to doing a step by step ible?

I'm glad you liked this small project. Sorry, I didn't take step-by-step pictures while doing it, it seemed so simple. All I have are the photos and text above. I hope it's enough to reproduce this periscope.

But thanks for your comment, I'll keep this in mind while working on my next project.

Interesting. Very. I have been looking for something like this for a while. My only question - how do we download the steps?
