Candy science is a fantastic way to demonstrate scientific principles using something kids love, candy! With these simple Colorful Candy Science Experiments, the biggest challenge is not eating all of your science supplies. These easy science projects are perfect for preschool, pre-k, kindergarten, first grade, 2nd grade, 3rd grade, 4th grade, 5th grade, and 6th grade students.
With Halloween coming there is a lot of extra candy around and if you are like me, you want to find ways to use up some of that candy without adding to your waistline. Thankfully, candy science is a fantastic way to explore science principles. Not only are these candy science experiments fun, but these hands-on simple science projects smell amazing, but the results are often beautiful and colorful! These science experiments using candy are perfect for preschoolers, kindergartners, grade 1, grade 2, grade 3, grade 4, grade 5, and grade 6 students.
For this set of candy science activities we wanted to explore what happens to different candies in water. The results were stunning rainbows that elicited lots of exclamations and wows from the kids! You will use lollipops, skittles, M and M’s, and other hard candy!
Candy Science Experiments
To do this Colorful Candy Science activity you will need the following materials. Chances are you have most of these supplies already in your home:
- A white shallow bowl or dish (or a clear one on a white cloth works, we want to be able to really see what is happening).
- Warm water
For our first test we decided to see what Skittles would do in the warm water. After some testing we discovered that it was best to have the Skittles on the plate, then add water to get the most beautiful designs and separation of colors.
Simple Science Experiments
Next we wanted to see if other candies would do the same thing, so we tested it in the same way, but using lollipops. The colors were not as intense but they behaved in the same way, with beautiful patterns emerging.
Next up we tested another favorite candy of ours, M&Ms. Again the colors behaved in the same way.
The science behind why the colors do not mix is known as water stratification. Each color creates a water solution that has slightly different properties such as density, salinity, and oxygenation. This creates a barrier that prevents the water from mixing and is why salt water and fresh water do not mix.
Candy Science Race
Next up we decided it was time for a Candy Science race! We wanted to see which would dissolve faster, the Skittles or the M&Ms.
We lined up our candies on opposite sides of our dish, then carefully added our warm water. Instantly, we saw a difference. The Skittles were much brighter.

Then after about a minute we had a clear winner. The Skittles created brighter colors and reached the middle of the dish faster.
Candy science projects
After all of this Candy Science we were inspired to create another experiment using dissolved lollipops. They smelled so good, we had to keep experimenting!
