    Can secret message come in color other than brown ? Let's see.

    What you will need
    Ingrediants

    1. 1 teaspoon (4.9 ml ) cornstarch
    2. 1/2 cup (.12 l )water , divided
    3. iodine


    Equipment's
    1. measuring cups & spoons
    2. microwave-safe bowl
    3. spoon
    4. cotton swab
    5. white paper
    6. small bowl
    7. sponge





    1. place the corn starch and 1/4 cup ( .06 l ) water in a microwave-safe bowl and stir.
    2. have an adult microwave the mixture on the high settings for 40 seconds
    3. stir again , then allow the liquid to cool
    4. use your ink and cotton swab to write a secret message on a piece of white paper and place it somewhere to dry.
    5. have an adult put several drops of iodine in a bowl and add remaining 1/4 cup ( .06 l ) water. IODINE IS POISONOUS , SO DO NOT TASTE OR DRINK THE LIQUID. dip a sponge in iodine mixture and lightly wipe the sponge over dried paper .Can you read your message? What color is it
