Invisible ink has been used for centuries for secret messages! The most common types include lemon juice (which appears when heated), baking soda solutions, and special chemical inks. Modern invisible inks are used in security applications like watermarks on currency and sensitive documents. Of course, drinking any ink is not recommended!
