No matter what age you are, receiving a Halloween party invitation written in invisible ink is intriguing and mysterious. It may take some practice with the invisible ink before you are ready to mail Halloween party invitations. Once the invitations are finished and distributed, you will need to give your guests the key or clues to make the ink visible.

Instructions

  1. 1

    Pour lemon juice into the bowl.

  2. 2

    Put the tip of the cotton swab into the lemon juice. The lemon juice acts as the invisible ink. Write a message on the white paper about the Halloween party.

  3. 3

    Let the lemon juice message dry for 10 minutes.

  4. 4

    Mail or give the Halloween party invitations to the guest. Include instructions on a separate sheet of paper as to how to read the invisible ink.

  5. 5

    To read the invisible ink message, hold up the Halloween party invitation to a heat source, such as a light bulb or sunshine. An iron on the cotton setting can be used to display message. The invisible message will begin to take form as it darkens to a pale brown colour, according to Science Fair Adventure.

Tips and warnings

  • Invisible ink mixture also can be made by mixing one teaspoon of baking soda mixed with one teaspoon of water.
  • Be careful not to be burnt or catch the paper on fire when trying to read the invisible message by the heat source.
