Create your very own invisible ink!
- Baking soda
- Cotton swab
- Grape juice or grape juice concentrate
- Cotton round/pad
Using a small bowl or cup, mix together ¼ of a cup of baking soda with ¼ of a cup of water.
Using the cotton swab or paint brush, begin to write your sentence on a piece of paper. Use the baking soda and water mixture as ink!
Allow your piece of paper to dry before revealing the secret message.
Gently wipe grape juice over your dry piece of paper using a cotton round\pad or paintbrush.
Your secret message should appear on the paper!
Good luck, Detectives!
