An easy-to-implement outreach chemistry activity showing the synthesis, isolation, and use of a copper-based pigment, malachite, with three paint binders is described. This activity is adapted from a traditional chemistry laboratory experiment and can be performed in a sandwich bag using plastic utensils within a 15 min time frame. Student group size is kept at five students maximum, allowing interaction between a large number of students over the course of a 3 h outreach event. This Science Technology Engineering Arts and Mathematics (STEAM) experiment combining chemistry with art has the advantage of demonstrating a chemical reaction by the observation of a precipitate and evolution of a gas, which most students find highly intriguing. Discussions about chemical reactions, physical and chemical changes observed, and the interplay of chemistry and art took place between the authors and the students, who were highly engaged.
