Make Invisible Ink
If anything is a prime example of a Sneaky Use project, it’s using everyday things to make invisible ink. (Sneaky fact: Casinos now use cards marked with symbols that are only visible when viewed with a special lens.) You can use a large variety of liquids to write secret messages. In fact, some prisoners of war used their own saliva and sweat to make invisible ink.
What’s Needed
Milk or lemon juice or equal parts baking soda and water
Small bowl
Cotton swab or toothpick
Paper
