Skittles Rainbow Experiment: Delicious At-Home Science
If you love color, you'll LOVE this Skittles rainbow experiment! It's a science and math activity all in one. The perfect way to use up left over holiday candy or a tasty way to teach your kiddos at home.
Candy Science Experiment Supplies
- Choose candies with a hard colorful coating.
- White plates
Skittles Rainbow Experiment Set Up
To get your experiment set up you'll want a white background, like a plate. Arrange your candies in a color pattern. Rainbow color orders give the prettiest outcome but you can play around with others as well.
- M&Ms: Laid out in repeating rainbows
- Fruit Mentos: Alternating colors
- Skittles: Instead of a Skittle rainbow my kids wanted to see how the warm and cool colors would work together. We had WAY less green ones to work with.
- Gobstoppers: Single candy and rainbow plate
Candy Rainbow Experiment
First record your hypothesis. What do you think is going to happen?
- Which candy color will move fastest?
- Which will be brightest?
- How long will the rainbow stay intact before mixing?
- What do you expect to see?
Add Water and Watch the Rainbow
Once you have your candies set up on plates, slowly add a little water to the center of each, making sure the water reaches the candy but doesn't submerge it.
Does the waxy chocolate affect the dissolving shell? What happens to the chocolate in water? How long will the color rainbow stay intact before mixing?
How quickly does the color run? Do any colors move faster than others? How is the candy center affected by the water?
The Gobstoppers were interesting. knowing they are made up of different layers of color we hoped to create a ring of colors using a single piece of candy on the plate.
A little disappointing in the multiple color results, we tried them in a full ring and they performed much better! Turns out there's only 2 colors in the Gobstoppers now.
Candy Rainbow Scientific Review
After you've recorded the progress over a 5 minute period, come back and see what's become of the candy itself.
- How much has dissolved in the water?
- How much color still remains? Has it blended or it is still a distinct rainbow?
- Are colors created that weren't originally there?
- Is the candy still edible?
Candy Science Is Colorful
Would you enjoy making a few candy rainbows at home? Which candy will you choose and how will you decide to arrange them? The big question is after your Skittles rainbow experiment are you going to EAT it?
