Message in a... spy pen?

Message in a... spy pen?

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 1Pick your weapon of mass secrecy!

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!

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? :-)

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.

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.

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.

I remember doing this in high school 20 years ago... I just figured it was a widespread thing kids did. :)
