Valentine STEM skittles experiment for kids

My daughter loves experimenting with Skittles and we had fun experimenting with the classic Skittles experiment, and adapting it for a little Halloween science, Christmas science and New Year STEM fun. We thought it would work just as well for Valentine’s Day so designed this Valentine’s Day Skittles experiment for kids, perfect for a little STEM exploration at home.

You don’t need much equipment. Just a big bag of Skittles, a white plate, and a jug of cold water. You could also find a timer if you want to record how quickly the colour changes.

The first thing to do is take out the red skittles from the bag and then make them into a heart shape on the plate.

Then pour a little water onto the plate, slowly enough that the skittles don’t move out of place, but enough to cover the sweets.

Quite quickly you can watch the colours leech from the Skittles. The food colouring in the Skittles is very strong and creates a pretty pattern, drawn to the centre of the plate.

So why does this happen? Well the Skittles are covered in sugar and food colouring which dissolve as the water touches them. The coloured water then slowly moves towards the centre of the plate.

The above process took about 2 minutes but we left the experiment out a little longer. Eventually all the colour come away from the sweets but the coloured water stays the same.

    This is such a cool little experiment, nothing something I’d have thought of doing myself. I’ve only used skittles in drinks before to make them colourful haha x

    What a great idea and a great way of making science fun for kids. I didn’t even think you could do anything with skittles other than eat them!
