No Ink Invisible Clue  

Materials: 

  • 2 blank sheets of white paper 
  • Pen or Pencil 

Instructions: 

  1. Begin with overlapping the two sheets of white paper. 
  2. Using the pencil, write a message on the piece of paper that is on top. Make sure you press firmly while writing. The pressure will overlap onto the sheet below. 
  3. Remove the top paper with the code, but be sure to hide it so your secret message is not revealed! 
  4. Gently begin shading with the pencil over top of the bottom sheet of paper to reveal the message and secrete code.
