How Does it Work?
Invisible ink is a substance that can only be seen under specific conditions or with the use of certain tools. There are several types of invisible ink, such as lemon juice, milk, or specialized pens and markers. Each type of ink has its own activation method, which can include heat, UV light, or chemical reactions.
Creating Invisible Ink Messages

Once you’ve written your message, you’ll need to reveal the invisible ink. There are a few ways to do this:

- Chemical Method: Apply a solution of iodine or grape juice to the paper using a cotton swab or brush. The solution will react with the lemon juice, making the invisible ink appear.
Other Applications of Invisible Ink
In addition to secret messages, invisible ink can be used for various purposes:
- Security: Invisible ink can be used to mark valuable items or documents as a security measure. Only those who know how to reveal the ink will be able to identify the marks.
