Liesegang Rings

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates. This activity is recommended for upper-level chemistry learners and requires observations over a period of days weeks and months. It's been documented that these reactions will last for up to 30 years. The operating guide details the chemical composition of the five different chemicals and gels, and provides documentation for articles to research for more recipes and background information.
