## Introduction: Cryptex

Just like in the Da Vinci Code. It works much like a bicycle combination lock and if one arranges the rings to spell out the correct password, the rings align to unlock it, and the entire cylinder slides apart. In the inner compartment of the cryptex, this is where secret information can be hidden.

This was sorta a school project. For an engineering project we had to invent something.

## Step 1: Materials

-(2) 2" PVC end caps
-(1) 1.5" PVC coupler
-(1) 1.5" PVC tubing (about 7")
-(1) 2" PVC tubing (about 7")
-(3) .5" x 5" x .125" clear acrylic strips
-Dremel Tool
-Superglue

## Step 2: Cutting

Cut the 2" PVC tubing into:
-(2) 2 1/8" pieces
-(5) 3/4" pieces

## Step 3: Sanding

Sand down the insides of the 2" PVC rings and also the inside/outside of the coupler, until it fits snuggly inside the 2" PVC ring. Do this 4 more times. Then cut a 1/2" notch in the 1 1/2" coupler, then glue to the inside of the 2" PVC ring.

## Step 4: Glue and Cut

Glue one of the 2 1/8" piece of the 2" PVC into the end cap, glue the 1 1/2" PVC to the other end cap. Then slide the 2" piece into the end cap but DO NOT glue.

Cut a 2 1/4" x 1/2" piece of PVC, then glue it onto the 1 1/2" PVC tube

Next you must decide what you want your password to be, then put the letters of the word you chose above the notch, then complete the rest of the alphabet on the ring, then slide the rings onto the 1 1/2" PVC tube.

But also make sure that you can create a riddle or something with your password. Mine was PIANO, and the riddle was.. i am a box that holds keys without locks, but can unlock your soul. What am i?

## Step 6: Finishing Touches

Just Put the other end cap on and glue on the acrylic strips. But only glue them onto the 2" PVC pieces that are in the end caps. And there you go, a cryptex!

probably as a hint to unlock the thing, like a word or name or page number

this is sorta hard to follow, i am not sure what is the key or what is the point of the clear pieces on top. could you make a video of you going over opening it and explaining more about everything.

The coupler is holding the rings in place, right? idk : /

i bought all the materials. Tried to make this for weeks. what do i get? 20\$ gone out of my pocket, and wasting 2 weeks of my life. T_T

It took me awhile to realize what you meant by "get your mind out of the gutter" I probably wouldnt have realized if you didnt mention it, should I be embarrassed?

well dude look at the pic and think... what does it remind you of?

pvc? will somebody just tell me what it means

it starts with p, has 5 letters, boys have it, girls dont...

Oh jeez... Are you really that superficial? And it's 'shut up', not 'shuttup'...
