Fun with colour changing - milk experiment

We started off with 4 colours in a shallow plate of milk.
We placed a cotton bud dipped in dishwashing liquid into the middle of the colours and waited for 10-15 seconds.

The colours rushed out to the edges of the plate.

We then made some adjustments to our experiment, e.g. placed the colours on the outside of the plate - they zoomed inwards. We are now thinking about what made this happen and why.
