What You Need:
- Baking soda
- Cotton balls or swabs
- White paper
- Watercolor set
- Measuring spoons
What You Do:
- Help your students measure out 4 tablespoons of baking soda and 4 tablespoons of water into a bowl and mix thoroughly to create a "secret mixture."
- Set down a sheet of paper and allow students to dip a cotton swab or ball into the mixture.
- Encourage students to paint their invisible picture or message onto the white paper. Allow the "magical paint" to dry completely.
- Have students use the watercolors to paint over the entire paper to reveal their secret painting!
Helpful Hint: Invisible messages make a great gift! Include directions on how the recipient can reveal the secret message.
