Science at the Library – Chromatography and Forensic Science

How many colors make black? Be amazed as black magically turns into vibrant purples, blues, greens, magenta, and more with just a drop of water! This hands-on science activity for children 5 and older introduces the concept of chromatography. Chromatography comes from the Greek word chroma meaning "color" and graphia meaning "writing". Chromatography is a fun way to explore the separation of color pigments.
