Crypto with Crayons

Now let's add some color to the art of hiding messages! This technique is so simple, even a 3 year old can do it.

• Get a piece of white paper, a color pen/marker and some wax crayons.
  
• Write your message on the paper with the marker.
  
• Now let's encrypt it! Color over the message with the crayons. Make sure that no part of the message is visible when you do this. (Tip: Darker colors do the trick faster!)
  
• Finally, when it's time to decrypt the message, take a coin and scratch over the colored portion and viola! Your message has appeared again. It is that simple!
