We took paints and milk and created marble milk paper in the classroom this week. It was a lot of fun to see the designs that created with each sheet we ran through the milk/paint mixture. It's a simple process of one cup of milk and water colors, food coloring, or paint applied to the milk surface and a plain sheet of paper laid on top. We think the process would have been more uniform with acrylic paints/oil-based paints, but it was still a fun activity with what we used. We allowed the paper to dry in the sunshine.
