White Crayon (or a taper candle)
Step 1: Using your white crayon, write your message on your paper. This may be tricky because it will be hard to see where you wrote. Make sure you are using a good firm pressure when you write otherwise you might not get a clear message. I like to write over my words a couple of times to make sure there is enough crayon down.
Step 2: Add watercolor paint right over top and the message will reveal itself! It’s fun to write a message and then give it to a parent or sibling to paint!
Why do you think this works? The wax in the crayon is acting as a resist and pushing the watercolor away so the paint won’t stick to it. Cool huh?
