Colour Changing Milk Activity

We had expired milk the other day, so before we let it go down the drain, it was first put to good use :)

We got ourselves a flat bowl and poured some milk into it. I then put some drops of blue and yellow food colouring onto the milk. Interestingly, in the milk, the colours did not dissolve. It just stayed there on the surface in the form of drops.

Next, I took a cotton bud, smeared the tip with some dish washing liquid, and handed it to Aishah for her to touch the tip on the drops of colours on the milk. 

Here starts the fun and magical part! The colour then moved away from the cotton bud and swirled around. I don't know whether you can imagine it from my description, you just have to try it yourself to understand! The pictures I put here just don't do justice for the actual magical swirling sensation!

Here's another picture clearly showing the blue and yellow colours starting to mix to become green. I then asked the girls to stir the milk until the colours really mix and the milk became green. The girls then started to paint on the newspaper using the cotton buds :)

Then we took another bowl and experimented with red and yellow. 

The girls really enjoyed watching the colours swirling around. And then came the mixing time! Stir, stir, stir!

Orange it is, followed by another round of painting. I think this activity made the ummi as amazed as the kids, if not more!
