Your kids may think you're a real live wizard when they see the colorful results of this Skittles science experiment. What they won’t know is that there is actually a lot of science behind those swirls and whirls of color.
The different colors in Skittles are composed of slightly different properties. When the warm water dissolves these colors, kids witness a phenomenon called water stratification. The different densities of each ingredient create a barrier between the colors and thus a very cool and colorful pattern.
