Suggested Family Activity 💌 Message in a Bottle
Have your family make a Message in a Bottle today. Grab an empty plastic water bottle and have each person write out a secret message to put inside. They can write it in code, such as using a simple number substitution of 1=A, 2=B, and so on. It is also very easy to make your own invisible ink. You can find several simple recipes online that use baking soda mixtures and liquids such as milk, lemon juice, vinegar, and water. Use a cotton swab to write out a message, roll it up, and send if off in your bottle. When they are ready to reveal their messages, have an adult help hold the paper over a candle flame to cause the chemical reaction that makes the writing visible.
