We're Peter, Emma, Aaron, Ixchel, and Kaitlyn, and we're in our school's science club. Our teacher gave us a special assignment. We need to come up with a colorful art display that doesn't use paints! We went to the most colorful place we know in San Francisco, a cool museum called the Exploratorium. Our question: how can we produce colorful art, without using paint?
