Experimenting with colour – #minicreations

IMG 1748

Recently it’s been mostly dry and sunny enough to go out in the garden or to the park after Joel’s afternoon nap. Yesterday, however, it was pouring with rain, so I had to think of something we could do indoors other than the usual toys that Andrew had been playing with whilst little brother was asleep. We’d done baking recently, and so had Granny so we have an abundance of cakes/biscuits, so that was less appealing. The other day when I was browsing Pinterest for something, I can’t even remember what exactly, I came across a cool science experiment to teach kids about colour mixing (it certainly was nothing to do with what I’d searched for at least). I didn’t pin it at the time, but remembered the concept, and recalled it just at the right moment.

When searching for it again last night, I found the pin! As you can see, the simple experiment involves filling two glasses with water and putting a small amount of different colour food colourings in each one, then sticking a piece of kitchen roll into each glass and the other end of each piece into a third glass. Over time the coloured water seeps up into the kitchen roll and down into the empty glass, where the colours mix and create a new colour.

The two colours that I could find in the cupboard were red and blue. The boys were fascinated to see what I was doing during the setting up, and to see that the colours were soaking up into the kitchen roll. We talked about odours and Andrew heaped me position the glasses whilst Joel flapped his arms in the high chair. It was quite a wait, however, until there was any sign of a new colour in the third glass, so we left it and went back to playing, and it had even stopped raining enough to go in the garden for a bit.

By tea time there was enough coloured water in the third glass to see its colour, and by bedtime it was a lovely deep purple, which I dipped a piece of kitchen roll into and it came out an almost Cadbury colour (purple is on my brain at the moment 😉 ) This morning when I shows him at breakfast what had happened, Andrew was very impressed! The magic of colour mixing.

This was an educational activity to spend some time on during a rainy afternoon. I’ve since started a ‘rainy days activities’ board on Pinterest, and will look for some more fun activities to pin. Give me a shout if you have any on Pinterest that I could add.

  2. What a great experiment! My 4yo is fascinated with colour mixing and we’ve done various things with paint, but I love this idea 🙂 #MiniCreations

    i am loving this experiment!! its super 🙂 xx

  4. Thats a good idea, I have a cupboard full of old food colouring!! it also works well with white flowers, they turn coloured over time.

    • Ruth says:

      Yes it’s great for old food colouring. Will try the flowers some time too, I’ve seen it before but I don’t think the boys have

    Lucas says – AWESOME!! It also means we get to do messy play as well……. That red water looks a bit like the Mummy juice the Mother always drinks!!!
    The Mother says – Lucas………..
