Invisible Ink Markers The purpose in which I was trying the use the pens did for not quite meet my expectations. However, I was still able to use them in my presentation to make a point. I wanted to be able to have the students write a group of words down on a piece of paper (without them knowing it was invisible ink), fold it up and set it aside to hear the message and then pull it back out to have the words they had written to have disappeared. The yellow definitely didn’t work; the blue not so much either…
