Here you are a cool experiment you can do at home. It’s very simple but I recommend you to use whole milk. The main reason is because the fat in the milk makes the experiment work.
You just need cotton swabs, dish washer, milk and food coloring. You first have to fill a plate with milk. Soap causes the molecules of fat to move. Colors combine in different ways and the effects are very beatiful!
Try to do it at home using other types of milk. Compare then the results with different types of milk: almond, cow, rice or coconut. Does it work?
