Colors of Skittles Experiment

Colors of Skittles Experiment | Science Fair Projects | STEM Projects
Let's find the secret rainbow inside the Skittles! We'll take different colored Skittles candy, add some water, and watch the colors separate.


The hypothesis is that the colors in the candy will separate out when water is added.

Method & Materials

You will cut a piece of filter paper into a circle, place a candy in the center, and add water to the candy. You can do this for each color of Skittles to see how many colors are actually inside each Skittle!
You will need filter paper, Skittles, a small cup of water, and a plate.


After a few minutes, you should be able to see rings of color around the candy. The colors that migrate the furthest from the candy have less of a mass than the ones closest to the candy.

Why do this project?

This science project is a fantastic way to introduce the concept of chromatography, while also providing a fun and engaging activity with colorful and delicious candies.

Also Consider

Experiment variations to consider include using different colors of candy, such as M&M's, and doing an experiment with dots of the candies' colors on a piece of filter paper, dangled above a cup of water (see video below).
