Have you ever wanted to send your friend a secret message that no-one else can read? Create your own “invisible ink” and write your own secret messages! For this program you will need Cardstock (or another thick paper). Measuring spoons, 3 cups or small bowls, a spoon, Q-tips or a small paint brush, old newspaper or cardboard, Paper Towels. Ingredients for Method 1: Water, Lemon or lemon juice, Iron (used with parental supervision) Ingredients for Method 2: Baking soda, water, turmeric, and rubbing alcohol. Note: Instead of rubbing alcohol another high percentage alcohol (40 percent or more) can be used. Water does work as well but the results won't be as intense.
