Published by Library Staff on

Did you know you can write secret, invisible messages using lemon juice? Squeeze some lemon juice into a bowl and mix in a few drops of water. Using a cotton Q-tip dipped in the liquid, write a message on a blank sheet of white paper. After your message has completely dried and canโ€™t be seen anymore, heat the paper by holding it close to a light bulb.
