Invisible Ink Formula Revealed

"What The F!*@ Does It Say"?

The secret is out!  The CIA recently released the formula for invisible ink.

Do you want to know how to make it? 

I am embarrassed to admit that I thought “invisible ink” was just for mystery books and spy movies.  Not true.

History buffs know that  invisible ink was actually used during World War One by German soldiers.

The directions are as follows:

1.

2.

3.

4.

I wrote them in invisible ink!  It actually seems pretty easy.

For real this is how you make it:

  • Mix 1 tablespoon of starch into a “tumbler” of boiling water.  Once water cools add ten grams of nitrate mix.

So the next question is how do you read invisible ink?

No clue.

For more information visit the CIA website.

Now that I know invisible ink is real, I am doing all my work in it!
