Rainbow in a Glass


Rainbow in a Glass

By Anne Marie Helmenstein, Ph.D.

This is a simple and fun experiment for demonstrating liquid density

This experiment takes advantage of density to create a rainbow in a glass. When you add sugar to a liquid, it causes the solution to become more dense. The more sugar you add, the more dense the solution is. If you have different solutions that are all different colors and densities, the colors will layer on top of each other — the denser, more sugary solutions will sit on the bottom and the lightest will sit on the top! Check it out here >
