Analog Text Encryption-Compression Technique





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!

    i'm illiterate. this helps me with my illiteracy.

    This is really cool... Suprisingly, i never thought about doing this. lol

    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.

    its actually still on here. so bizarre to watch after you haven't slept.

    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
