Magic rainbow milk: a simple science experiment to delight kids!
At the Mud Mates headquarters, we are big fans of messy play. My kids just love getting messy, and of course it provides such a great opportunity to learn.
However….. I’m all for quick and easy, and to be honest, not TOO much mess. My littlies (particularly Miss 2’s) attention spans are very limited, so I’m not too keen to spend copious amounts of time setting up an activity only for them to be bored after 5 minutes.
So when a friend introduced me to Magic Rainbow Milk I thought ‘this is right up my alley’. And I was right. This is really cool, and Miss 2 thought it was pretty darn awesome too!
It’s also cheap, quick and easy to set up and if you do it outside (highly recommended!), there’s not that much mess to clean up afterwards.
What you’ll need to create rainbow milk:
– Milk – full fat not skim
– Shallow dish or bowl
– Food colouring
– Dishwashing liquid (in a small bowl)
– Cotton buds
For the extension of the activity (see below) you’ll also need:
– baking soda
– vinegar (and a dropper or spoon or cup to pour it out of)
Pour a thin layer of milk into your dish.
Add a couple of drops of food colouring onto the surface of the milk (one colour or a couple of different colours).
Dip a cotton bud into the dishwashing liquid and then in the milk, aiming for the centre of a spot of food colouring.
Watch and enjoy.
Miss 2 loved watching the colours explode so we repeated the steps a few times until we had muddy milk. Then we emptied it out and started again, and again, and again. 🙂
And this is why your child needs their Mud Mates on, as inevitably a bowl of rainbow milk will end up down their front.
But never fear, their clothes underneath will be clean and dry. Simply pop your Mud Mates through the wash to clean them and they’re quick to dry so you’ll be ready for more messy play in no time at all.
After some time when Miss 2’s attention was starting to wane, in order to keep the activity going for a bit longer, I introduced some good ole’ baking soda and vinegar.
Miss 2 had fun sprinkling (actually, dumping is more accurate) the baking soda onto the milk then adding the vinegar – first with a dropper, then a teaspoon, then just by pouring it on. It was fun to watch the Magic Rainbow Milk foam and bubble away.
But, why stop there! I grabbed a straw and let Miss 2 have a blast making bubbles by blowing into the coloured milk.
If you haven’t done this before, just do it! So simple yet effective and fun for all ages.
