Easy Invisible Ink

Paint over your drawing and your picture magically appears!

We recently threw a science themed birthday party for my older daughter. We set up 3 rotating stations with experiments for the kids to do, and concluded with a dry ice show by my real-life-scientist husband. One of the stations was invisible ink. It involved mess, a hair dryer and soggy paper. Here is the version we should have done instead. It’s easy and can be kept fairly clean and of course, hair dryer free.

If you draw with a white crayon, it seems to be invisible. When you paint over the crayon drawing, the paint slides off the waxy crayon residue, revealing your message or drawing. Any paint will work, but for ease and less mess, we used dot paints, which the kids love. They had a blast revealing their messages.

Looks like nothing is there? Just wait!

This technique can be used for any theme. My kids wanted to do “winter” pictures but it could just as well be about anything. Scribbles are great too! You could do this to represent the first day of creation, (light and dark) using black paint over the white crayon. It could also work for the second day of creation (when the waters are separated). Color a large block of white in the center of the page. Paint over it with blue and voila! The waters split with white in between. The blue paint would go well with Kriyat Yam Suf too.  Share any other ideas you have, or photos of what you came up with!

Time:
Active: 30 minutes

Age: 2-8

Materials:
white  paper
paint (we used dot paint but any will work)
white crayons

materials

Process:

Color with the white crayon on the white paper. Make sure to press down firmly for best results. Words are fun if your kid knows how to write but pictures are just as good. Make sure you have drawn everything you want before starting to paint, as you cannot go back and draw more on that page once the paint is applied.

Paint over the areas you colored. Watch as the paint slides off the crayon and your message is revealed!
