Valentines Skittles Science Project | Little Bins for Little Hands

Science, Valentine’s Day, and candy all in one perfectly simple activity to try with the kiddos this month. Our Valentines Skittles science project is a fun twist on the classic experiment. You will love how easy it is to set up and try with kids of all ages for this special day. Quick results make it super fun for kids to observe and try over and over again. Simple science and STEM makes everyday learning and lesson planning easy.



Of course, you need to try out candy science projects for Valentine’s Day! Do you remember our Skittles Science Activity?  I thought it would be fun to give the kids a heart themed science activity so we changed up the original a bit with colors and patterns.

Our Valentines skittles science project is an awesome example of water density, and kids love this fascinating candy science! The candy science experiment uses a classic candy, Skittles! You could also try M&M’s compare the results! Check out our floating M’s here too.



We have a whole season of fun Valentine’s Day theme science activities to try. Repeating experiments in different ways really helps to solidify understanding of the concepts being presented. Holidays and seasons present numerous occasions for you to re-invent some of these classic activities like this simple Skittles activity.

Check out our classic skittles video to watch the action before trying yours!

The perfect, simple to set up science for any occasion or holiday.


You will want to set this up someplace where it won’t be bumped into but where you can easily watch the process unfold! Kids will have so much fun creating their own arrangements and patterns with the skittles. You should definitely have multiple plates handy!

Open the cupboards and get set for a little kitchen science…

  • Purple, Pink, and Red Skittles Candy
  • Water
  • White Plates or Baking Dishes (flat bottom is best)
  • Heart Theme Cookie Cutters


Check out the photo process in the following pictures and then find the written steps for this simple Valentines Skittles science project below. A cookie cutter isn’t necessary but adds a fun addition to the theme.


You can also try arranging the Skittles into a Valentine theme shape like hearts or arrows! It’s a great hands-on activity for kids of multiple ages to enjoy (especially if there’s a bit of tasting involved).  Remember you can try this with M&M’s too and compare or contrast the results.


You can easily turn this into an experiment by changing some variables. Remember to only change one thing at a time.

  • You can experiment with both warm and cold water or other liquids like vinegar and oil. Encourage the kids to make predictions and really observe the differences!
  • Or you can experiment with different types of candies!

Keep your eyes peeled for the results!


  • Set out a bowl of skittles or you can let the kids sort them out themselves!
  • Let your child have fun arranging them in a pattern around the plate alternating colors in any number they like- singles, doubles, triples, etc…
  • Pop in a Valentine shaped cookie cutter to the center of the plate just to add a little more of the theme and some additional color.
  • Before pouring in the water ask your child to form a hypothesis- What will happen to the candy when it is wet?  This is a great time to work in a little deeper learning, you can find information to teach your child about the scientific method here.
  • Carefully pour water into the center of cookie cutter until it just covers the candy. Be careful not to shake or move the plate once you add the water or it will mess up the effect.

Watch as the colors stretch and bleed out away from the Skittles, coloring the water. What happened? Did they mix?  What if you used clear soda instead would that change the outcome?

Note: After a while, the colors do begin to bleed together.


Skittles Science demonstrates a process called stratification. The simple definition is that stratification is the arrangement of something into groups. Specifically, this is water stratification, and water has different masses with different properties that create the barriers you see within the different colors of candies.


While we were looking up information about stratification online some sources said that each color of Skittles have the same amount of food coloring that is being dissolved off the shell and so as it spreads it doesn’t mix when they meet. You can read about this concentration gradient here.

This experiment is quick and gives kids that instant gratification they so crave! Being curious, trying different theories, investigating, and exploring are all important when it comes to science. Not every science experiment needs to be deep and probing!

While this Valentines skittles science project is a simple activity for the kids, they are usually in awe of it (especially the first time they see it).  Hands-on, easy to grasp, and pretty to look at it is really a great activity/experiment to include in your holiday/special occasion lesson plans.

Mix up easy Valentine’s Day science with heart oobleck!
