This project is way fun and turns out soooo cooool! I did it with my 6th graders when teaching about color, but I think it could be done with younger grades as well. This could be done with any size paper, I decided to make mine small because I used small containers to create them in. We made 4 (1 using primary colors, 1 warm, 1 cool, and 1 complimentary) and then glued them all onto a black sheet of paper. Here is how to create this cool marbling effect:
1. Layer about 1 inch of Shaving Cream onto a paper dish (or trays) *I bought my shaving cream at the dollar store. They had huge cans for just $1!
2. Level it out with a piece of cardboard as a scraper
3. Use water based paint. I used the water colors. Paint directly on top of the shaving cream. Use different compositions like concentric circles, stripes, half moons, etc.
4. Then using the back of the brush or a pointed stick or tooth pick. Swirl the paint. Do not push it down deep into the shaving cream. The paint will stay on the top.
5. Cut paper small about 6"x4." Lay paper on top of the design and press down (printing technique). Pull the paper off. The shaving cream will appear to be all smeared but wait.
6. Use the piece of Posterboard to squeeze off the excess shaving cream. Like magic, the design stays on the paper.
You can reuse the shaving cream until it gets drab. Just mix it in and paint again and again.
