A dramatic demonstration of surface tension, density, and insolubility. When this clear maze is inverted, a brightly-colored liquid drips down in unpredictable directions, ultimately pooling together at the bottom. The droplets' travel path is a-mazing, never the same! Great as a discussion or inquiry starter. Why do the drops change shape as they fall? What makes some of them 'hesitate' before flowing downward? What can you infer about the density of the liquids in the maze? Not for children under three years.
