Message in A... Spy Pen?





Introduction: Message in A... Spy Pen?

About: I'm a product designer, who believes in working backwards. Instead of taking technology and seeing what problems I can solve with it, I take problems and see what technology can do for the problem. If curre...

Is it a pen, or a super secret way to pass messages to... umm... err... someone?

Perhaps it will be useful with a chummy coworker, or if you work from home like me; your super sexy office-mate-wife!

Yeah it's not encrypted, but who writes hand written notes anymore?  That more than anything else provides security that no amount of electronic hacking can crack.

Step 1: Pick Your Weapon of Mass Secrecy!

Pick your favorite disposable ballpoint pen.  I chose opaque. Translucent didn't seem right for a spy message pen, too revealing.

The only important thing is that you can separate the ballpoint head / ink assembly from the body of the pen. This will be your secret message compartment. Although if you couldn't get it open you could use some sort of top secret telepathy technology to transfer your message into the essence of the pen itself!

Step 2: Disassembly and Arming Instructions...

1.  Remove pen cap, and separate ballpoint head and ink assembly from the body of the pen. Be mindful not to break the ink well during this step. Unless of course you need a distraction. Then by all means. Also if you need to take part in some stealthy covert night missions you can cover your exposed skin such as face and hands in the ink so you'll be invisible. Or do you need invisible ink for that?

2.  Cut a piece of paper to the width of the ink well.

3.  Arm your weapon of mass secrecy with a well written love note or some other important message.

4.  Tape your message to the ink well. Don't use too much tape. You don't want it to be difficult to remove. You need just enough tape to prevent the note from slipping as you roll it around the ink well.

5.  Roll note tightly around the ink well, being sure not to break the ink well.
6.  Insert ball point pen and ink well assembly back into pen body.

7.  Put cap back on pen.  
Unless you have some more writing to do.  

Note: One of the beauties of using a pen as your secret message device is that the recipient can write a message back to you with the same pen.


Step 3: Deliver Your Payload!

With super spy stealth deliver your innocuous pen to the desired target. And ever so subtly hint that they should take a look inside the pen.  If they give you a confused look, take the pen and run! They're probably a double agent... If running isn't an option, or you need a convenient diversion be prepared and read the emergency self-destruct instructions.
Emergency Self-Destruct Instructions:
  1. Firmly grasp the pen with both hands.
  2. Break pen in half making sure to rupture the inkwell.
  3. Flail arms vigorously to send drops of ink and clothing destruction towards unsuspecting enemies.
note: Remember activating the emergency self destruct feature will not only create a diversion, but hopefully erase any readability of the message by soaking it through with the ruptured ink well.

Watch the awesomeness unfold!

If you are reading this you have successfully completed your mission, or umm... are just still reading through the instructable. It's now time to let the device of mass secrecy cause all sorts of havoc and enjoy countless hours of note passing with no one being the wiser.

Or in my case score points with my wife for passing her love notes! Thanks for your interest, hope it was worth at least a few minutes of your time.

    that would be good to hide an messege in.sorry abour that..

    That would be goodnto hid messege in.

    Actually, i wudnt think it advisable to put the ink on your skin. if u do, it will look like you got into a street fight with a pro kick boxer.

    It is like a message in a bottle! I use to put my name inside my pens on the ink cartridge to try and catch pen thieves.

    Ha! What a coincidence, I had that idea a few days ago!
    Have you noticed that people sometimes come up with ideas at the same time? :-)

    Actually, I have! I design products for a living. And, I can't tell you the number of times where I think of something that I think would make an amazing product! Then after researching I find out it was indeed so awesome that somebody has made it and is selling it to make lots of money.

    Real Funny Dude... The Reading of the Instructions is more enjoyable than the Doing of it...
    Will try it out with my wife too sometime soon. I just hope it doesn't come back with a list of Grocery Items in the Sense of Ultimate Secrecy.

    This is so epic! I HAVE to try this one. The way you wrote the instructable was really cool as well. Thank you for posting this, + 5* rating!

    Thanks. More than anything I did this to practice my instructable writing skills. Sometimes it's good to do something simple and focus on the presentation. On the more complex instructables I've done I find it harder to spend as much time on the style of the write-up because I am so focused on trying to make it reproducible and get all the technical information out.

    I did this once. I think I have an 'ible for it... but the pictures and stuff were bad... lol

    Yes I see what you are saying, more simple it is the easy it is to understand. Also you mind doesn't get crowded or overloaded with unnecessary info.

    The clear "crystal" pens make good non-secret message holders, too.
    Roll it outside-out to make sure the message can be seen. I put "This Pen Was Stolen From My Desk, Please Return It." it gets a laugh and relieves some of the shame of being a pen thief.

    Ooh, yes: name and shame the guilty parties, eh? Very good idea which I will try at work :) I will have the "stolen" text part inside and set the rolled up note showing outside just saying "Read me". Extra surprise, evil grin.

    That is a good idea. I should do that with some. My 4 year old son and wife are always making pen raids from my office desk. I'll buy a box of 20 and a few weeks later will be wondering where they all went.

    Of course it will probably just encourage them more because they'll think it's funny. I guess I will be picking up a box of clear pens to leave a "This pen was stolen from Dad's desk. Please return it." so they can have extra fun laughing as they steal them from my desk.

    Jeje, I used to do something very similar for the final exams in elementary school, I would make the exam first, then write everything I could about the exam in very tiny letters and pass it to my not so smart frends. I'ts quite curious how they turned out to be grat businessmen!
    Nice simple instructable that really just makes me nostalgic.
