Skittles Rainbow Ring

Colored stripes spread inward. Ask students to predict what will happen. Arrange candies in ring and add shallow water. Key idea: Candy coatings dissolve and pigments diffuse through water. Ask: Why do the colors stay in lanes for a while? Safety and cleanup: No eating after demo. https://static1.squarespace.com/static/5e41c4ed5ae4ac656412e50f/t/66d8866331669e32ea8ebdbd/1725466212693/Skittles%2BRainbow%2BExperiment.pdf
