Want to write a secret message to see if your friends can crack the code and read the message? This is an easy and quick way to produce invisible ink. All of the supplies can be found in anyones house.
Obtain: Baking Soda, class of water, piece of paper, and grape juice.
Procedures: Mix some baking soda into the water, add enough that the water appears cloudy. Dip your fingers into the class and write out the desired message on the piece of paper. Allow the paper to dry. Spill a small amount of grape juice on the paper so that it covers the entire message. The message text should chance color and you should be able to read the message. If this does not work try increasing the amount of baking soda in the water.
To see if your friends can crack the code, tell them you left them a note and lead them to only the black piece of paper and a glass of grape juice. See if they are clever enough to find the hidden message.
Stay tuned for a video demonstration and an explanation of the chemistry involved.
