Our science experiment 2

Today we did another experiment my question was what did the coloring attach to? with very fatty milk, food coloring(the milk has to be whole milk with the dark blue cap or it wont work)  and dish washing detergent 

•  we put whole milk in a bowl and and added: pink, blue and green food coloring I suspect that the food coloring attached to the fat in the milk, we added dish washing detergent  and the colors started to PARTY! dancing and going bazookers, they were spinning and going all over the milk, here are some cool photos,
