Don't destroy the highlighter trying to get it open. You can use lemon juice, milk, baking soda, cornstarch and iodine, and a white crayon. Invisible ink with lemon juice making invisible ink is a lot of fun, you can pretend you are a secret agent as you keep all your secret codes and messages hidden from others.

To make an invisible ink message that will be revealed by heat, first pour 1 teaspoon (5 ml) of lemon juice into a small bowl.

I’m putting that to the test. Using invisible ink is a cool way to hide your messages until its time for them to be read. Set the iodine aside for later. Painting the tonic water on paper under a uv blacklight and testing with a uv flashlight occasionally.
