Even though slime is one of the popular DIY projects, there is something that might interest you if you like art, which also combines chemistry since there is a change in chemicals. It is called DIY foam paint. Here’s what you need to make it:

1) Three cups of Shaving Cream(preferably foam, not gel)
2) 1 cup of flour (I had best results not using the full cup)
3) 1 cup of white glue (preferably Elmer’s glue)
4) Food coloring or paint
5) Ziploc sandwich bags
6) Sturdy paper or board (poster board, tag board, cardboard, watercolor paper, or paper plates)

First, measure out all the ingredients, except for any coloring, into a large mixing bowl.
Next, mix the shaving cream, flour, and glue together without over mixing. (You want to keep the air bubbles in the shaving cream.)

After that, divide the white puffy paint mixture between 3 to 4 small bowls and add a few squirts of food coloring or paint to each bowl, stirring in, but again being careful not to over mix. Now, spoon the puffy paint into sandwich bags. Seal each bag, then cut a small corner off.
Then, squeeze the foam paint through the small hole onto your paper or board, making puffy lines, dots, and designs as desired.

Finally, let dry overnight. You’ll notice the foam paint gets even puffier over time then sets, but is still puffy to the touch even after it dries.
Now, your foam paint should be as foamy as soap in a bathtub. Have fun!
