Invisible Ink Activity

Making invisible ink is a fun & easy summer activity for kids.  You can write secret messages for them to decode or vice-versa!


You will need:

• 1 teaspoon Baking Soda
• 2 Tablespoons Water
• Cotton Swab
• Blank White Paper
• Grape Juice
• Small Paintbrush (like a watercolor paintbrush)

First, mix together the water & baking soda in a small bowl or cup.  Dip the cotton swab in the solution and write your message on a blank white piece of paper.  Let the paper dry for 3-4 hours or overnight.

To decode the secret message, pour a small amount of grape juice in a small bowl or cup and use a small paint brush to paint over the secret message.  Your message will appear!  The message will become clearer once the grape juice dries.

The message I wrote in invisible ink for Connor was our scripture memory verse for this week:

Remind them to be subject to rulers, to authorities, to be obedient, to be ready for every good deed- Titus 3:1
