How To Make Invisible Ink

 

These are our 5 favorite ways to make homemade invisible ink.  Some require adult supervision because of the need for heat to make the writing appear. 

 

 

Lemon Juice Invisible Ink
1 Lemon cut in half
Small bowl
Small paint brush or cotton swab
Paper
Squeeze a lemon half into the small bowl.  Dip the paint brush or Q-tip into the lemon juice and then write your secret message on the paper with the brush.  Let the juice dry completely. To read the message hold the paper 6" from a light bulb.  The heat of the light bulb (can not be an LED bulb) will make the message appear! You can also have an adult use an iron to iron over the message. 

 

 

 

Vinegar or Baking Soda Invisible Ink

Vinegar or Baking Soda
Water
Small Bowl
Small paint brush or Q-tip
Paper
Sponge or larger paint brush
Grape juice

 

Choose if you will be using Vinegar or Baking Soda.  In the small bowl mix 1 Tablespoon of Vinegar (or Baking Soda) with 1 Tablespoon of water.  Mix the two ingredients together.  Dip a small paint brush or cotton swab in the mixture and write your secret message on the paper.  Let the writing dry.  To reveal the message use a sponge or larger paint brush and paint the paper with grape juice.

 

If you need to make a larger quantity of the invisible ink for a birthday party simply mix the ingredients in a 1/1 ratio.  For example: 1/2 Cup of baking soda with 1/2 Cup of water. 

 

 

 

 

Milk Secret Messages

Milk
Small bowl
Paintbrush or Q-tip
Paper
Light that gives out heat or an iron

 

Paint or swab a message onto paper with Milk.  Let the paper dry.   To see the message hold next to a candle, light bulb or swipe over the paper with an iron. 

 

 

No Ink/span
Lay a piece of paper on top of another piece of paper.   Using a pencil write your message on the top piece of paper.   Remove the top piece of paper.  To reveal the message use a pencil to lightly color over the bottom piece of paper.

 

Crayon or Candle

White Crayon or a white candle
Paper
Colored markers or water colors

 

Write your secret message on a piece of paper using  a white crayon or white candle.  When you want to reveal the message color over the message with a darker marker or water colors.  Your secret writing will appear like magic!
