I love the Skittles rainbow experiment and have done it many times over the years. I really wanted to give my kindergarten students the opportunity to try it out. All you need are Skittles and water! Since I did this with a group of kindergarten children at school, I incorporated some math into our experiment.

I let students choose a variety of colours of Skittles and create a pattern on their plate. We placed a roll of tape in the middle of the plate. This helped keep the Skittles in a circle as they created their pattern. The tape helped students by allowing them to focus on creating their math pattern by keeping the Skittles in place.

Once the tape is removed, the pattern of Skittles already looks beautiful! Next we added some warm water onto the plate. Make sure to pour enough water to touch all of the Skittles.

Within a few seconds, the water begins to dissolve the Skittles and the colour begins to run to the middle of the plate. This creates a beautiful rainbow of colours! When the Skittles begin to dissolve and the colours create their pattern, students were quickly able to see if they had missed a Skittle in their pattern.

I love the endless number of patterns possible with the Skittles for this rainbow experiment. My students loved watching their rainbow form right before their eyes. I plan to try it out again and next time my students want to check the difference between using warm and cold water.
