For kicks, I made a special Jupiter with yellow, white, and orange plus the famous red spot! I used a butter knife to get the striped effect and hung it in front of our Christmas tree so the lights look like stars. By this time, my son had already moved on to playing trains in his room, but I was still enjoying exploring the colors and textures! He was pretty interested in my Jupiter the next day at breakfast though, so we explored more.
The nice thing about this project is that if you want, you can match the color of each planet, and the relative sizes by using large and small plates and by cutting each accordingly.
