Skittles Rainbow Science Experiment for Kids

We love it when an activity involves minimal use of things, especially when we already have that at home.  Your little one will love this simple Science experiment that takes a few minutes.

Things you will need: 

  • Skittles or M& M or Gems. You can use any candies from any brand.
  • A White Plate
  • Water

These are all you need to make this fun Experiment.


Place Skittles in a circle along the rim of the plate.  Create patterns by alternating colours.

Kids will get to practice using their fingers together to pick up and place the skittles on the plate. This action strengthens their fine motor skills. It’s both fun and helpful, especially if your child is a Toddler!

Add warm water to the middle of the plate such that it also touches the outer edge of the candies.

Now, Wait 30 seconds to watch the colours dissolve into the water.

Hot water releases colour faster than cold water. When you use cold water for this experiment, it takes longer for the colours to dissolve in water.

The results are stunning!  You will see all the colours dissolve and move to the centre. When you mix paints, you can form new colours. Experiment with your finger to mix, swirl and create a whole range of new colours. Discover the magic of colour mixing!

The Science Behind this Rainbow Science Experiment

Skittles are colourful candy treats that are coated with sugar and food colouring. When you add warm water, the sugar and colour start to dissolve.

The sugar molecules move around to areas of lower concentration, so each Skittle will dissolve evenly and stay in its own lane. It’s like a tiny science experiment that’s fun to watch!
