The Skittles Rainbow Experiment: A Wee Science Activity Your Kids Will Love

Looking for something to keep the wee ones entertained that's actually a bit class? This one's a guaranteed winner — it takes about five minutes to set up, uses things you probably already have in the house, and the results are pure magic. We do this regularly at Ladybirds and every single time, the children's faces are an absolute picture.

Say hello to the Skittles Rainbow Experiment. 🌈

The finished result — a stunning rainbow pattern that forms right before your eyes!

What You'll Need

•  1 bag of Skittles (the original ones work best)

•  A white plate

•  Warm water

That's it! Dead simple.

How to Do It

1. Arrange your Skittles in a circle around the edge of the plate — you can group them by colour or mix them up for a more dramatic effect.

2. Slowly pour warm water into the centre of the plate until it just reaches the Skittles. Don't pour it directly onto the sweets.

3. Now — step back and watch the magic happen!

Pure delight — watching the rainbow form is the best bit!

What Actually Happens?

The sugar and food colouring in the Skittles dissolve into the water and start moving towards the centre of the plate. Because each sweet is a different colour, you get beautiful streaks of colour flowing inward — creating a gorgeous rainbow pattern.

The reason the colours don't mix in the middle? Each stream of coloured sugar water has roughly the same density, so they kind of push against each other rather than blending together. Pretty brilliant, wha'?

Every plate turns out slightly different — which makes it even more exciting to see!

Make It Even More Fun

Want to turn it into a wee science lesson? Ask your child these questions before and after:

•  What do you think will happen when you add the water?

•  Which colours do you think will move the fastest?

•  Why do you think the colours don't mix in the middle?

There's no wrong answer — it's all about getting them curious and thinking. You might be surprised what they come out with!

Proud of their creation — as they should be! Science has never looked so good.

Tips for the Best Results

•  Use warm water — not boiling, not cold. Warm works best.

•  Pour slowly and steadily around the inside of the Skittles ring.

•  Don't move or tilt the plate once the water is in.

•  The more Skittles you use, the more dramatic the rainbow!
