This is an alternate method of secret writing that’s completely different from encoding and decoding message ciphers. It involves using special inks that are invisible until something is done to make them appear on the paper. There are hundreds of formulas to make these special inks and some formulas even have multiple ways to develop the ink. Some recipes involve special chemicals, but many invisible inks can be made using materials that you have in your home. Watch the video and I’ll share a few recipes and teach you more about this method.

Some of these are really simple, right?  I like the wet and dry method a lot. When using the milk writing method, how do you think you would get the milk to change color so that the message could be read?

  4. I’ll give you a hint… milk comes from a living thing (a cow), so can you find a way to heat it a little so that it browns before the paper does? (Do not use a flame.)
