Science: Milk and food colouring

When we first added the food coloring to the milk the food colouring spread a little but not enough to notice. When we added the dish washing liquid the food colouring spread throughout the milk and moved in a motion. The more dish washing liquid we added the more  it would ripple. The closer we put the dish washing liquid the faster the dish washing liquid would react to the food colouring forcing it to move faster. We have seen a variety of colours being mixed together forming other colours. There is a chemical reaction that causes the colours to move. This relates to our every day life as we use dish washing liquid to remove grease from pans. To make this an interesting science fair we could use different milks like soy milk and others to see if we get the same reaction.
