Patriotic Crystal Making in a Dish

This very exciting lab uses our new crystal collecting paper to grow and contain beautiful, large crystals for study. The chemicals provided make brilliant red (potassium ferricyanide), white (epsom salts), and blue (copper II sulfate) cyrstals from non-hazardous salts. Crystal paper can also be purchased separately. Developed by Ron Williams. Includes materials for 10 student groups and instructions.
