Invisible ink messages are a fun and easy way to send secret messages to friends. They can be made using a variety of household items, and they are surprisingly difficult to detect. To send an invisible ink message, you will need:

• A lemon or lime
• A cotton swab or paintbrush
• A piece of paper

To write your message, simply dip the cotton swab or paintbrush into the lemon or lime juice and write your message on the paper. The juice will not be visible at first, but it will become visible when the paper is heated. To read the message, simply hold the paper over a light bulb or other heat source.
