Introduction: Analog Text Encryption-Compression Technique

Using only a rubber band and permanent marker or ink pen, it is possible to encrypt and decrypt a text message using only the muscle power in your fingers.

Step 1: Let's Stretch Before Begining

Take a rubber band that is wide enough to write on, and stretch it tightly around a flat surface. The surface could be a book, or in this case, a roll of duct tape. The tighter the stretch, the better the results.

Step 2: The Pen Is Mightier

With the band stretch to its limit, place your message carefully on the band. It helps to place the letters close together. Neatness doesn't count.

Step 3: Time to Relax

With the message complete, we can take the rubber band off the roll, and let it relax. The message will be unreadable to all but the keenest of eyes.

Step 4: Reading Is Fundamental!

To read the message, one need only stretch the band, and voila!

Reminds me of when there is written text on a ballon that it extremely small before you blow it up. Fun!

I remember doing this as a kid. I think I saw it on The Littles.

The littles? That show with those tiny, mouse/people things? Wow, I thought I was the only one.

This is how we used to write our names on swimming goggle straps when I was a kid- it looks neat even if the letters are only slightly compressed.

I saw this on the news awhile ago because college students were using this technique to cheat on tests

the problem with a balloon, though, is the fact that you have to blow up the entire balloon to read the text. If the idea is only to transmit a message covertly, then a balloon is fine. However, if you want the message to be read with minimal detection, a rubber band is more fitting.

I remember seeing something like this on Zoom's detective show within a show--The Bloodhound Gang--back when I was a kid. They used a walking stick and a leather belt. The belt was wrapped around the walking stick, and then the message was written so one letter was on each wrap of the belt. Since the message spanned several rows around the stick, the message was "encrypted" unless you rewrapped it around the stick.

They also used to use that technique in wars. They used different sized objects at different stations, so the messages would be useless if they fell into the wrong hands.
