Science experiments are incredibly fun with kids. We did this cool science project with Skittles today to help with weather week.

Spoiler: it produces a rainbow!

It’s incredibly easy and you can get kids as young as 2 involved with putting together the entire experiment!

My 4-year-old loved taking part in the experiment and I even let her eat some Skittles at the end!

Super cool Skittles experiment

This science experiment is budget-friendly too. If you have Skittles in your house, you have all the ingredients you need!

I’ve even included some tips on other candies and ideas you can do with this experiment to really get your child’s brains working.

They all can be done with kids ages 2 and up and are a great way to keep kids occupied while you’re at home.

How to Put Together A Science Project with Skittles

Grab either a big bag of Skittles or two small fun packs of them. I used four because we experimented twice today.

Have your child place the Skittles around the inside of a circular plate.

Poor just a little warm water in the inside of the plate. You need just enough water to fill the bottom of the plate completely.

Wait and watch! The colors will start to spread to the middle and create a cool pattern in a matter of minutes!

It’s okay if the kids bump the table slightly. The Skittles science experiment will still work great! Trust me, my daughter has bumped the table a few times when we do this.

Why Does This Experiment Work?

Skittles are coated with sugar and food coloring. What happens when you get sugar wet? It absorbs in the water!

The same effect is happening during this science experiment. The water hits the Skittles and the sugar coating melts into the water. Since the water is all in the middle of the plate, it only has one way to go.

Does This Skittles Science Experiment Work with Milk?

I have tried this experiment with milk, and it does not work. The Skittles just sit there. You can even move the plate slightly back and forth and they still will not dissolve.

Sprite, on the other hand, will create the same effect!

What Other Candies Can I Use?

This experiment also works great with M&Ms and Smarties. The M&Ms will create a similar effect while the Smarties will melt a little slower and will be more faded because of its colors.

Other Ideas to Make This Experiment

Here is a quick list of other ideas you can do to keep kids entertained with this simple science experiment.

– Use a square plate instead of a round plate

– Use a toothpick or small paintbrush to create a design once the Skittles have dissolved their colors

– Group the Skittles by color to make a big rainbow

– Put Skittles inside the middle of the plate to create a face or design to see how they react

Do you think this would work on a thick paper plate?

If there is wax or plastic on the top, it could work, but paper may soak up the water and colors so it doesn't work as well.
